Try this:

try
{
    string Path = @"C:\Users\William\Pictures\Documents\Apple iPhone\";
    DirectoryInfo di = new DirectoryInfo(Path);
    FileInfo[] fiArr = di.GetFiles("*.jpg");

    for (var i = fiArr.Length; i > 0; i--)
    {
        var fri = fiArr[i - 1];
        var path = Path + i.ToString() + ".jpg";

        fri.MoveTo(path);
    }
}
catch { }
