My application is raising an unauthorized access error. While running my application, I try to access a directory in the following location: Application.UserAppDataPath.

The Problem: It says I do not have permission to access the Application.UserAppDataPath directory

Is there a way to set permissions within my application source code?

Something like:

Application.UserAppDataPath.SetPermissions()

Its probably a UAC issue, Try running your application as an elevated process, and see if the error persists

@RedEye: You can right-click on your program's shortcut and choose 'Run as Administrator'.

Looking at your comment, you say this is your code:

StreamReader sr = new StreamReader(Application.UserAppDataPath);

Application.UserAppDataPath is a directory, not a file. If you try to open that directly, it's the same as trying to open a file one level below the AppData folder, which you really don't have permission to do.

Use Path.Combine to construct a path to a file inside the AppData folder, i.e.

string fileName = Path.Combine(Application.UserAppDataPath, "settings.xml");
StreamReader sr = new StreamReader(fileName);

Of course this is just an example - in reality you should probably be using a sub-folder inside AppData specific to your application.

This is most likely the cause, and one that I've seen too often. You **definately** want to create a subdirectory underneath AppData that is specific to your application and use that.
