更新時(shí)間：2018年05月21日 14:14:46 作者：邊界流浪者

這篇文章主要為大家詳細(xì)介紹了C#訪問共享文件夾或者磁盤，需要用戶名密碼，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了C#訪問共享文件夾或者磁盤的具體代碼，供大家參考，具體內(nèi)容如下

SharedTool：

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Runtime.InteropServices;  
  
namespace ConsoleApplication5  
{  
  public class SharedTool : IDisposable  
  {  
    // obtains user token     
    [DllImport("advapi32.dll", SetLastError = true)]  
    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);  
  
    [DllImport("Advapi32.DLL")]  
    static extern bool RevertToSelf();  
    const int LOGON32_PROVIDER_DEFAULT = 0;  
    const int LOGON32_LOGON_NEWCREDENTIALS = 9;//域控中的需要用:Interactive = 2     
    private bool disposed;  
  
    public SharedTool(string username, string password, string ip)  
    {  
      // initialize tokens     
      IntPtr pExistingTokenHandle = new IntPtr(0);  
      IntPtr pDuplicateTokenHandle = new IntPtr(0);  
  
      try  
      {  
        // get handle to token     
        bool bImpersonated = LogonUser(username, ip, password,  
          LOGON32_LOGON_NEWCREDENTIALS, LOGON32_PROVIDER_DEFAULT, ref pExistingTokenHandle);  
  
        if (bImpersonated)  
        {  
          if (!ImpersonateLoggedOnUser(pExistingTokenHandle))  
          {  
            int nErrorCode = Marshal.GetLastWin32Error();  
            throw new Exception("ImpersonateLoggedOnUser error;Code=" + nErrorCode);  
          }  
        }  
        else  
        {  
          int nErrorCode = Marshal.GetLastWin32Error();  
          throw new Exception("LogonUser error;Code=" + nErrorCode);  
        }  
      }  
      finally  
      {  
        // close handle(s)     
        if (pExistingTokenHandle != IntPtr.Zero)  
          CloseHandle(pExistingTokenHandle);  
        if (pDuplicateTokenHandle != IntPtr.Zero)  
          CloseHandle(pDuplicateTokenHandle);  
      }  
    }  
  
    protected virtual void Dispose(bool disposing)  
    {  
      if (!disposed)  
      {  
        RevertToSelf();  
        disposed = true;  
      }  
    }  
  
    public void Dispose()  
    {  
      Dispose(true);  
    }  
  }  
}

案例：

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.IO;  
  
namespace ConsoleApplication5  
{  
  class Program  
  {  
    static void Main(string[] args)  
    {  
      using (SharedTool tool = new SharedTool("administrator", "12345678", "192.168.1.101"))  
      {  
        string selectPath = @"\\192.168.1.101\c$";  
  
        var dicInfo = new DirectoryInfo(selectPath);//選擇的目錄信息  
  
        DirectoryInfo[] dic = dicInfo.GetDirectories("*.*", SearchOption.TopDirectoryOnly);  
        foreach (DirectoryInfo temp in dic)  
        {  
          Console.WriteLine(temp.FullName);  
        }  
  
        Console.WriteLine("---------------------------");  
        FileInfo[] textFiles = dicInfo.GetFiles("*.*", SearchOption.TopDirectoryOnly);//獲取所有目錄包含子目錄下的文件  
        foreach (FileInfo temp in textFiles)  
        {  
          Console.WriteLine(temp.Name);  
        }  
      }  
      Console.ReadKey();  
    }  
  }  
}
