public static void Empty(this System.IO.DirectoryInfo directory)

{

    foreach(System.IO.FileInfo file in directory.GetFiles()) file.Delete();

    foreach(System.IO.DirectoryInfo subDirectory in directory.GetDirectories()) subDirectory.Delete(true);

}

System.IO.DirectoryInfo directory = new System.IO.DirectoryInfo(@"C:\...");

directory.Empty();

System.IO.DirectoryInfo di = new DirectoryInfo("YourPath");

foreach (FileInfo file in di.GetFiles())

{

    file.Delete(); 

}

foreach (DirectoryInfo dir in di.GetDirectories())

{

    dir.Delete(true); 

}
