Coping files to a directory

Question

Good evening teachers. Could you please tell me why i can't copy two or more files to this directory. Thanks again for your relentless eye opener.

 DirectoryInfo myDr = new DirectoryInfo(@"G:\Elias");

            if (!myDr.Exists)

            {

                myDr.Create();

            }

            FileInfo myF1 = new FileInfo(@"G:\test9.txt");

            myF1.CopyTo(myDr.FullName + (@"\tet9.txt" + @"\test.xml"));

            //myDr.Delete(true );

            Console.ReadKey();
