Question

Is there any difference between these two methods of moving a file?

System.IO.FileInfo f = new System.IO.FileInfo(@"c:\foo.txt");
f.MoveTo(@"c:\bar.txt");

//vs

System.IO.File.Move(@"c:\foo.txt", @"c:\bar.txt");

Take a look at “Remarks” section in this MSDN page http://msdn.microsoft.com/en-us/library/akth6b1k.aspx :

If you are going to reuse an object several times, consider using the instance method of FileInfo instead of the corresponding static methods of the File class, because a security check will not always be necessary.

I think this difference is most significant between File (Directory) and FileInfo (DirectoryInfo) classes.
