C # to format (indent, align) C #

Question

We have a code generator that prints the schema of this database to automate our internal n-tier architecture. The result is several C # classes, one for each file.

In the code, in order to execute all the lines, we try to adhere to indentation and formatting as much as possible, but whenever you open a file in Visual Studio, formatting is a mistake. The quick ctrl-k, ctrl-d fixes it, but obviously this reformatting is lost the next time the class is created.

What I would like to know is there a way that I can somehow automatically format the contents of a text file in the same way as Visual Studio does?

Pseudo code

Create "code" object, passing text file to constructor Invoke "format" method Re-save text file 

Any help is greatly appreciated.

EDIT: I have to clarify - I want to be able to call formatting from my C # code, which creates a text file containing my generated C #. The code format can be standardized (not required for each developer), and I do not want to install any third-party applications.

It seems that I remember there a namespace containing many classes for creating C # in C #: http://msdn.microsoft.com/en-us/library/system.codedom(VS.80).aspx , but I'm not sure if it contains any classes that could help.

FURTHER EDITION: My code generator is a winforms application deployed through a one-time installation. It is used by many developers within the company. I need a solution that does not require each developer to have the tool installed on their machine.

Expand answer to Cherian:

NArrange will allow you to do a lot of code formatting. It is open source and the source is available on their website, so you can potentially integrate and reinstall it using your tool.

You only need a DLL and just look at exe how to call formatting. It will also back up formatted code. This is a really good tool if it suits your needs.

Answer 2

Take a look at Narrange . You probably need to automate these things as part of the assembly.
Not sure if it meets all your requirements. Quote:

NArrange is a .NET code decoder. which automatically organizes the code of members and elements inside .NET. classes.

Answer 3

You can use CodeDOM and CSharpCodeProvider. This is all in the Microsoft.CSharp and System.CodeDom namespaces.

She is an example of a property:

 StringWriter writer = new StringWriter(); CSharpCodeProvider provider = new CSharpCodeProvider(); CodeMemberProperty property = new CodeMemberProperty(); property.Type = new CodeTypeReference(typeof(int)); property.Name = "MeaningOfLifeUniverseAndEverything"; property.GetStatements.Add(new CodeMethodReturnStatement(new CodePrimitiveExpression(42))); provider.GenerateCodeFromMember(property, writer, null); Console.WriteLine(writer.GetStringBuilder().ToString()); 

This code will generate:

 private int MeaningOfLifeUniverseAndEverything { get { return 42; } } 

CodeDOM is a fairly common way to generate code. It’s good that you can create several languages. Perhaps you can find CodeProvider Erlang.NET?

You may be able to make multiple shortcuts using CodeSnippetExpression.

Answer 4

To correctly retreat the code programmatically, you will need the Microsoft.CodeAnalysis.CSharp nuget package and the .NET framework 4.6+. Code example:

 public string ArrangeUsingRoslyn(string csCode) { var tree = CSharpSyntaxTree.ParseText(csCode); var root = tree.GetRoot().NormalizeWhitespace(); var ret = root.ToFullString(); return ret; } 

Single line:

 csCode = CSharpSyntaxTree.ParseText(csCode).GetRoot().NormalizeWhitespace().ToFullString(); 

You can also use NArrange to sort methods in your cs file, organize usage, create regions, etc. Note that NArrange does not indent.

Answer 5

Only if you use the code generator as a complement to VS - each developer will have different settings.

Answer 6

Here's how to do it from a macro or add-in context:

 var dte = (EnvDTE80.DTE2)System.Runtime.InteropServices.Marshal.GetActiveObject("VisualStudio.DTE.8.0"); dte.ExecuteCommand("File.OpenFile", filename); dte.ExecuteCommand("Edit.FormatDocument", filename); dte.ActiveDocument.Close(vsSaveChanges.vsSaveChangesYes); 

A warning. As @Greg Hurlman says, the output will depend on the current user settings.

Edit:

Unfortunately, your method requires that I have a VS instance running next to my winforms application. Can you come up with a way to create a VS instance from my application (if possible)?

I think it is possible to do this from your Win.Form application. However, you will have to have Visual Studio installed on the computer with the code.

Try the following:

 var dte = (EnvDTE80.DTE2)Microsoft.VisualBasic.Interaction.CreateObject("VisualStudio.DTE.8.0", ""); dte.ExecuteCommand("File.OpenFile", filename); dte.ExecuteCommand("Edit.FormatDocument", filename); dte.ActiveDocument.Close(vsSaveChanges.vsSaveChangesYes); 

Keep in mind that you will need references to the assembly of EnvDTE80.dll.
