DirectoryInfo d = new DirectoryInfo(@"E:\Images\");
FileInfo[] infos = d.GetFiles("*");
int i = 0;
foreach (FileInfo f in infos)
{
    i = i + 1;
    File.Move(f.FullName, Path.Combine(f.Directory.ToString(), Convert.ToString(i)) + f.Extension);
}

DirectoryInfo di = new DirectoryInfo("Folder_of_interest");

foreach (FileInfo fi in di.GetFiles())
{
    fi.MoveTo("new_file_name");
}

那应该让您开始.

That should get you started.
