Access to path is denied when string is defined and not when using quotes

Question

I am having a very strange issue right now. I am attempting to get the files of a directory by using this code:

public static string[] fileList = Directory.GetFiles(@File.ReadAllText(Settings.localdir.Trim()));

However, when I do this, I get this error:

Access to the path 'C:\Users\lazho\Desktop' is denied.

But when I do this code:

public static string[] fileList = Directory.GetFiles(@"C:\Users\lazho\Desktop");

It works without any errors. I have no idea why one would throw an error when they both equal the same value. Any Ideas?

PS I have already tried this:

public static string dir = @File.ReadAllText(Settings.localdir.Trim());
    public static string[] fileList = Directory.GetFiles(dir);

Your SecurityException is from File.ReadAllText method. you can not read drive C without permission.
