C#如何访问共享文件夹或者磁盘

本文实例为大家分享了C#访问共享文件夹或者磁盘的具体代码，供大家参考，具体内容如下

SharedTool：

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Runtime.InteropServices;

    static extern bool LogonUser(string pszUsername, string pszDomain, string pszPassword,  
      int dwLogonType, int dwLogonProvider, ref IntPtr phToken);  
  
    // closes open handes returned by LogonUser     
    [DllImport("kernel32.dll", CharSet = CharSet.Auto)]  
    extern static bool CloseHandle(IntPtr handle);  
  
    [DllImport("Advapi32.DLL")]  
    static extern bool ImpersonateLoggedOnUser(IntPtr hToken);

    static extern bool RevertToSelf();  
    const int LOGON32_PROVIDER_DEFAULT = 0;

    private bool disposed;

    {  
      // initialize tokens

        if (bImpersonated)

      finally

          CloseHandle(pDuplicateTokenHandle);  
      }  
    }  
  
    protected virtual void Dispose(bool disposing)
