Using Directory.GetFiles on my .net site

Question

When I built my .net site, I got the file paths using Directory.GetFiles (@ "D: \ project \ images");

But when I deployed it to an Internet server, I need to change the link of this folder, can you help me, how can I do this? can i use relative link in Directory.GetFiles () or how?

Answer 1

in the web.config file there is something like:

<configuration> <appSettings> <add key="ImagesFolder" value="\Images" /> </appSettings> </configuration> 

then in your ASP.NET C # code you can use:

 var ImagesFolder = ConfigurationManager.AppSettings["ImagesFolder"]; var files = Directory.GetFiles(Server.MapPath(ImagesFolder)); 

remember that you need to add a reference to the System.Configuration assembly or you cannot add a using statement and gain access to the ConfigurationManager .

this way there are no hard-coded values, and you can write down the value you want for this appsetting by editing the web.config file in the expanded folder on the web server.

Answer 2

Put the path in your web.config. In any case, you do not have to be hardwired coding methods. What if this changes in the future?

In your settings add:

 <appSettings> <add key="myPath" value="D:\project\images"/> </appSettings> 

... and then called from the application:

 var myPath = WebConfigurationManager.AppSettings["myPath"]; 

If you really want to go crazy, check out the web.config transforms so that when you publish, your release configuration will be converted and applied for you!

Answer 3

The correct way to do this is with Server.MapPath, which maps the virtual path in your web application to the physical path on the server.
