Better way to check if a Path is a File or a Directory?

by

From How to tell if path is file or directory: 

// get the file attributes for file or directory
FileAttributes attr = File.GetAttributes(@"c:\Temp");

//detect whether its a directory or file
if ((attr & FileAttributes.Directory) == FileAttributes.Directory)
    MessageBox.Show("Its a directory");
else
    MessageBox.Show("Its a file");

Update for .NET 4.0+

Per the comments below, if you are on .NET 4.0 or later (and maximum performance is not critical) you can write the code in a cleaner way:

// get the file attributes for file or directory
FileAttributes attr = File.GetAttributes(@"c:\Temp");

if (attr.HasFlag(FileAttributes.Directory))
    MessageBox.Show("Its a directory");
else
    MessageBox.Show("Its a file");
