C# File.ReadAllText() throws "wrong" exception when dir path given - why?

C# method File.ReadAllText(string filePath) does not accept a directory path as argument - it needs a path to a file. I understand that.

But why does it in this case throw an UnauthorizedAccessException instead of an ArgumentException? I think this is not intuitive.

Has anybody an explanation that makes me feel better about this?

This happens when your final exe file needs some privilleges.

Try to run as an admin.
