Copy method can't be used with folder name arguments, and also your argument order is wrong.

Definition of the method is

public static void Copy (string sourceFileName, string destFileName);

both arguments should be filenames, not directories.

So you can use

File.Copy(mypath, folder+"\\" + Path.GetFileName(mypath));

You're trying to copy a directory using File.Copy(sourceFilename,destFilename). On top of that, the destination can't be a directory path

destFileName String

The name of the destination file. This cannot be a directory or an existing file.

To copy a file into a new directory you need to construct the new full file path and reverse the order of the arguments:

Directory.CreateDirectory(folder);

...

var fileName=Path.GetFileName(myPath);
var destPath=Path.Combine(folder,fileName)

File.Copy(myPath,destPath);
