用Directory.Delete删除一个目录下大量文件时，出现超时的问题

Question

最近做了个windows服务，让它在预定的时间里，开始执行一个删除文件的动作.如删除文件夹A，而且A文件夹下有大量文件（6万多个），用Directory.Delete作删除时，怀疑出现操作超时，不知为何？下面是我的删除代码。
                               try
                            {
                                DirectoryInfo dirPath = new DirectoryInfo(statePath);
                                string dirName = dirPath.Name;                                
                                DateTime dFileTime = Convert.ToDateTime(dirName);
                                if (dFileTime <= dTime)
                                {
                                    Directory.Delete(statePath, true);
                                    WriteLog("删除文件[" + dirPath.Name + "]时成功：");
                                    Thread.Sleep(2000);
                                }
                            }
                            catch(Exception delEx)
                            {
                                WriteLog("删除文件时出错：" + delEx.Message);
                                continue;
                            }

Answer 1

Directory.Delete(statePath, true); 删除根目录就可以了呀
看看Exception提示说的啥吧,

Answer 2

直接删除要删目录就可以了,Directory.Delete(FolderPath, true);
