本文介绍通过Windows Management Instrumentation (WMI) 来管理共享目录的方法，包括检查共享目录是否存在、建立及断开信任连接、远程创建和删除共享目录。

本文主要介绍如何使用WMI来查看共享目录是否存在、如何建立信认、如何断开信认、如何远程建立共享目录，删除共享目录

代码如下：

using System;
using System.Collections.Generic;
using System.Text;
using System.Management;
using System.Diagnostics;
using System.Threading;

            get { return timeout; }
            set { timeout = value; }
        }

        string wqlSelect = string.Empty;
