如何将桌面路径添加到app.config文件？

Question

I am creating an C# win form application where user can specify any location to save a file. But, in default I need to provide the desktop path. But the desktop path changes depend on the Windows version, I found that: Environment.GetFolderPath(Environment.SpecialFolder.Desktop); can get the desktop path of any windows version. But the problem is how do I add this code to App.config file? Is there are special xml code block for this.

Answer 1

You have to add a settings-file to your project. There you need to create a property in the application-scope. This property you can access by

string path = Properties.Settings.Default.Path;
if(string.IsNullOrEmpty(path))
{
   path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
}

Answer 2

Go through AppDomain.GetData and AppDomain.SetData
Have a constant like DESKTOP_DIRECTORY in you application & set its value to SpecialFolders.Desktop
You can then use AppDomain.GetData to retrieve it back.
You can then use it in your App.config file.
