Check Drive Exists(string path)

Question

How to check the drive is exists in the system from the given string in WPF. I have tried the following

Ex: FileLocation.Text = \"K:\\TestDriv

Answer 1

string drive = Path.GetPathRoot(FileLocation.Text);   // e.g. K:\

if (!Directory.Exists(drive))
{
     MessageBox.Show("Drive " + drive + " not found or inaccessible", 
                     "Error", MessageBoxButton.OK);
     return;
}

Of course, additional sanity checks (does the path root have at least three characters, is the second one a colon) should be added, but this will be left as an exercise to the reader.
