Hi Friend,

It is the default nature if you are deleting a subdirectory within your application, your app domain will restart. This removes all session data. To alleviate this issue, only add/remove directories outside your application home directory.

So keep the folder where you want delete operation to be performed out side application folder.

Hi,

if (Directory.Exists(folderPath))
                    Directory.Delete(folderPath, true);

----

Or Else Use This ....

System.IO.DirectoryInfo d = new System.IO.DirectoryInfo(folderPath);
                if (d.Exists)
                    d.Delete(true);
