C# - "Access Denied" for App Data

Question

I have written a application with C#.But,I continually get an error message of "access denied" for "App Data" under my user profile (password protected user account).BTW,I'm using Win7.

Here is my code:

string path = string.Concat(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), "//Programım//");

Since we can't assume the obvious, `path` does exist when you put a breakpoint on this line and navigate to that path manually, right? — Austin Salonen, Sep 01 '11 at 17:11
From what operation are you getting this? That 'I' looks funny, what culture is the app/OS using? — leppie, Sep 01 '11 at 17:17
Side note: "//Programım//" is not valid path/portion of a path. You either want "\\Programım\\" or @"\Programım\". — Alexei Levenkov, Sep 01 '11 at 17:18
@Alexei Levenkov: If you knew better, you would realize it makes absolutely no difference... — leppie, Sep 01 '11 at 17:22
@Selo: Are you trying to delete that directory with `File.Delete`? Please provide more info. — leppie, Sep 01 '11 at 17:24
@Selo, if you are using File.Delete, it won't work for a directory. It will also throw "access denied" if the file is read-only. http://msdn.microsoft.com/en-us/library/system.io.file.delete.aspx — Tangurena, Sep 01 '11 at 17:25

I would use System.IO.Path.Combine(...) instead of string.Conact(...) in this situation. Like this...

string path = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), "Programım");

The result of path in your original code might not be what you are actually expecting.

Once you are sure your path value is correct then call System.IO.Directory.Delete(...) like...

Directory.Delete(path, true);

If that still is not working, then there may be some other security permission problems with files in that directory, or with the directory itself. See the MSDN page for all of the exceptions that can be thrown from the Delete method and the reasons why.
