How to get the current project directory from C # code when creating a custom MSBuild task?

Question

Instead of running an external program with a hard path code, I would like to get the current Dir project. I am calling an external program using a process in a user task.

How should I do it? AppDomain.CurrentDomain.BaseDirectory just gives me the location of VS 2008.

Answer 1

You can try one of these two methods.

string startupPath = System.IO.Directory.GetCurrentDirectory(); string startupPath = Environment.CurrentDirectory; 

Tell me which one is better for you?

Answer 2

 using System; using System.IO; // This will get the current WORKING directory (ie \bin\Debug) string workingDirectory = Environment.CurrentDirectory; // or: Directory.GetCurrentDirectory() gives the same result // This will get the current PROJECT directory string projectDirectory = Directory.GetParent(workingDirectory).Parent.FullName; 

Answer 3

If the project is running in IIS Express, Environment.CurrentDirectory may indicate where IIS Express is located (the default path will be C: \ Program Files (x86) \ IIS Express), and not where your project is located.

This is probably the most suitable directory path for various projects.

 AppDomain.CurrentDomain.BaseDirectory 

This is the definition of MSDN.

Gets the base directory that the assembly recognizer uses to search for assemblies.

Answer 4

It will also give you the project directory by moving two levels up from the current executable directory (this will not return the project directory for each assembly, but this is the most common option).

 System.IO.Path.GetFullPath(@"..\..\") 

Of course, you will want to include this in some kind of error / error handling logic.

Answer 5

If you want to know what the directory where your solution is located, you need to do the following:

  var parent = Directory.GetParent(Directory.GetCurrentDirectory()).Parent; if (parent != null) { var directoryInfo = parent.Parent; string startDirectory = null; if (directoryInfo != null) { startDirectory = directoryInfo.FullName; } if (startDirectory != null) { /*Do whatever you want "startDirectory" variable*/} } 

If you only allow the GetCurrrentDirectory() method, you get the build folder regardless of whether you debug or release it. Hope this help! If you forget about checks, it will be like this:

 var startDirectory = Directory.GetParent(Directory.GetCurrentDirectory()).Parent.Parent.FullName; 

Answer 6

I was looking for this too. I have a project that runs HWC, and I would like to leave the website outside the application tree, but I do not want to store it in the debug (or release) directory. FWIW, the decision made (and this too) defines only the directory in which the executable is executed.

To find this directory, I used

 string startupPath = System.IO.Path.GetFullPath(".\\"). 

Answer 7

Another way to do it

 string startupPath = System.IO.Directory.GetParent(@"./").FullName; 

If you want to get the path to the bin folder

 string startupPath = System.IO.Directory.GetParent(@"../").FullName; 

Maybe there is a better way =)

Answer 8

Another imperfect solution (but perhaps a little closer to perfection than some others):

  protected static string GetSolutionFSPath() { return System.IO.Directory.GetParent(System.IO.Directory.GetCurrentDirectory()).Parent.Parent.FullName; } protected static string GetProjectFSPath() { return String.Format("{0}\\{1}", GetSolutionFSPath(), System.Reflection.Assembly.GetExecutingAssembly().GetName().Name); } 

This version will return the current projects folder, even if the current project is not a Startup Project for the solution.

The first drawback is that I missed all the error checks. This can be fixed quite easily, but it should only be a problem if you save your project to the root of the drive or use the connection in your path (and this connection is a descendant of the solution folder), so this scenario is unlikely, I don’t I'm quite sure that Visual Studio can work with any of these settings anyway.

Another (more likely) problem that you may encounter is that the project name must match the folder name for the project so that it is found.

Another problem that may arise is that the project must be located inside the solution folder. This is usually not a problem, but if you used the Add Existing Project to Solution option to add a project to the solution, it may not be how your solution is organized.

Finally, if you application will modify the working directory, you must save this value before you do this, because this value is determined relative to the current working directory.

Of course, all this also means that you should not change the default values ​​for the parameters of your projects Build → Output path or Debug → Working directory in the project properties dialog box.

Answer 9

Try it, it's just

 HttpContext.Current.Server.MapPath("~/FolderName/"); 

Answer 10

I had a similar situation, and after the futile Googles, I announced a public string that modifies the string value of the debug / release path to get the project path. The advantage of using this method is that since it uses the currect project directory, it does not matter if you are working from the debug directory or the release directory:

 public string DirProject() { string DirDebug = System.IO.Directory.GetCurrentDirectory(); string DirProject = DirDebug; for (int counter_slash = 0; counter_slash < 4; counter_slash++) { DirProject = DirProject.Substring(0, DirProject.LastIndexOf(@"\")); } return DirProject; } 

Then you can call it whenever you want, using only one line:

 string MyProjectDir = DirProject(); 

This should work in most cases.

Answer 11

After I finally finished my first answer regarding public lines in order to get an answer, it became clear to me that you can probably read the value from the registry to get the desired result. As it turned out, this route was even shorter:

First, you must enable the Microsoft.Win32 namespace so that you can work with the registry:

 using Microsoft.Win32; // required for reading and / or writing the registry 

Here is the main code:

 RegistryKey Projects_Key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\VisualStudio\9.0", false); string DirProject = (string)Projects_Key.GetValue(@"DefaultNewProjectLocation"); 

Note on this:

I am using Visual Studio 2008 Professional Edition. If you are using a different version (i.e. 2003, 2005, 2010, etc.), then you may need to change part of the "version" of the SubKey line (i.e. 8.0, 7.0, etc.).

If you use one of my answers, and if it is not so much to ask, I would like to know which of my methods you used and why. Good luck.

Answer 12

Use this to get the project directory (worked for me):

 string projectPath = Directory.GetParent(Directory.GetCurrentDirectory()).Parent.FullName; 

Answer 13

I used the following solution to get the job done:

 string projectDir = Path.GetFullPath(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"..\..")); 

Answer 14

Based on Gucu112 answer , but for a .NET Core Console / Window application, it should be:

 string projectDir = Path.GetFullPath(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"..\..\..")); 

I use this in an xUnit project for Windows.

Answer 15

Try:

 var pathRegex = new Regex(@"\\bin(\\x86|\\x64)?\\(Debug|Release)$", RegexOptions.Compiled); var directory = pathRegex.Replace(Directory.GetCurrentDirectory(), String.Empty); 

This solution, which differs from others, also takes into account the possible assembly of x86 or x64.

Answer 16

This solution works well for me, on Develop, and also on TEST and PROD servers with ASP.NET MVC5 through C # :

 var projectDir = Path.GetDirectoryName(AppDomain.CurrentDomain.BaseDirectory); 

If you need the project directory in the project configuration file, use:

 $(ProjectDir) 

Answer 17

The best decision

 string PjFolder1 = Directory.GetParent(AppDomain.CurrentDomain.BaseDirectory). Parent.Parent.FullName; 

Another solution

 string pjFolder2 = Path.GetDirectoryName(Path.GetDirectoryName(Path.GetDirectoryName( System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase))); 

Check it out, AppDomain.CurrentDomain.BaseDirectory worked for me in the last project, now I get the debug folder .... the selected good answer just DOES NOT WORK!.

 //Project DEBUG folder, but STILL PROJECT FOLDER string pjDebugFolder = AppDomain.CurrentDomain.BaseDirectory; //Visual studio folder, NOT PROJECT FOLDER //This solutions just not work string vsFolder = Directory.GetCurrentDirectory(); string vsFolder2 = Environment.CurrentDirectory; string vsFolder3 = Path.GetFullPath(".\\"); //Current PROJECT FOLDER string ProjectFolder = //Get Debug Folder object from BaseDirectory ( the same with end slash) Directory.GetParent(pjDebugFolder). Parent.//Bin Folder object Parent. //Project Folder object FullName;//Project Folder complete path 

Answer 18

If you really want to make sure you get the project source directory, no matter what bin output path is set to:

1. Add the command line of the event before assembly (Visual Studio: Project Properties → Assembly Events):

   echo $(MSBuildProjectDirectory) > $(MSBuildProjectDirectory)\Resources\ProjectDirectory.txt

2. Add the ProjectDirectory.txt file to the Resources.resx of the project (if it does not already exist, right-click the project → Add new item → Resource file)

3. Access from code using Resources.ProjectDirectory .

Answer 19

 using System; using System.IO; // Get the current directory and make it a DirectoryInfo object. // Do not use Environment.CurrentDirectory, vistual studio // and visual studio code will return different result: // Visual studio will return @"projectDir\bin\Release\netcoreapp2.0\", yet // vs code will return @"projectDir\" var currentDirectory = new DirectoryInfo(AppDomain.CurrentDomain.BaseDirectory); // On windows, the current directory is the compiled binary sits, // so string like @"bin\Release\netcoreapp2.0\" will follow the project directory. // Hense, the project directory is the great grand-father of the current directory. string projectDirectory = currentDirectory.Parent.Parent.Parent.FullName; 

Answer 20

This works on VS2017 configurations with the MSBuild Core SDK.

You need NuGet in EnvDTE / EnvDTE80 packages.

Do not use COM or interoperability. nothing .... bullshit !!

  internal class Program { private static readonly DTE2 _dte2; // Static Constructor static Program() { _dte2 = (DTE2)Marshal.GetActiveObject("VisualStudio.DTE.15.0"); } private static void FindProjectsIn(ProjectItem item, List<Project> results) { if (item.Object is Project) { var proj = (Project) item.Object; if (new Guid(proj.Kind) != new Guid(Constants.vsProjectItemKindPhysicalFolder)) results.Add((Project) item.Object); else foreach (ProjectItem innerItem in proj.ProjectItems) FindProjectsIn(innerItem, results); } if (item.ProjectItems != null) foreach (ProjectItem innerItem in item.ProjectItems) FindProjectsIn(innerItem, results); } private static void FindProjectsIn(UIHierarchyItem item, List<Project> results) { if (item.Object is Project) { var proj = (Project) item.Object; if (new Guid(proj.Kind) != new Guid(Constants.vsProjectItemKindPhysicalFolder)) results.Add((Project) item.Object); else foreach (ProjectItem innerItem in proj.ProjectItems) FindProjectsIn(innerItem, results); } foreach (UIHierarchyItem innerItem in item.UIHierarchyItems) FindProjectsIn(innerItem, results); } private static IEnumerable<Project> GetEnvDTEProjectsInSolution() { var ret = new List<Project>(); var hierarchy = _dte2.ToolWindows.SolutionExplorer; foreach (UIHierarchyItem innerItem in hierarchy.UIHierarchyItems) FindProjectsIn(innerItem, ret); return ret; } private static void Main() { var projects = GetEnvDTEProjectsInSolution(); var solutiondir = Path.GetDirectoryName(_dte2.Solution.FullName); // TODO ... var project = projects.FirstOrDefault(p => p.Name == <current project>); Console.WriteLine(project.FullName); } } 

Answer 21

Directory.GetParent (Directory.GetCurrentDirectory ()). Parent.Parent.Parent.Parent.FullName

Gives you a project directory.
