Cannot create a file when that file already exists when using Directory.Move

Question

I am trying to move the directory from one location to another location on the same drive. I am getting \"Cannot create a file when that file already exists

Answer 1

You don't need to create Directory first, it will throw IO Exception, if destination directory exists, Move method automatically creates it for you:

string sourcedirectory = @"F:\source";
string destinationdirectory = @"F:\destination";

if (Directory.Exists(sourcedirectory))
{
    if (!Directory.Exists(destinationdirectory))
    {
         Directory.Move(sourcedirectory, destinationdirectory);
    }
}
