Folder Creation and Deletion in C#

Here I am going to create and delete folder in the Software installation Directory. Delete Directory with containing files and folders

--------------------------------------------------------------------
if (Directory.Exists(String.Format(@"{0}\Temp\", Environment.CurrentDirectory)))
{
   System.IO.DirectoryInfo downloadedMessageInfo = new DirectoryInfo(String.Format(@"{0}\Temp\", Environment.CurrentDirectory));
   foreach (DirectoryInfo dir in downloadedMessageInfo.GetDirectories())
   {
      dir.Delete(true);
   }
   System.GC.Collect();
   System.GC.WaitForPendingFinalizers();
   Directory.Delete(String.Format(@"{0}\Temp\", Environment.CurrentDirectory), true);
}
------------------------------------
To create directory

Directory.CreateDirectory(string.Format(@"{0}\Temp", Environment.CurrentDirectory));
