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;  

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);//选择的目录信息  

        DirectoryInfo[] dic = dicInfo.GetDirectories("*.*", SearchOption.TopDirectoryOnly);
        foreach (DirectoryInfo temp in dic)
        {
          Console.WriteLine(temp.FullName);
        }  

        Console.WriteLine("---------------------------");
        FileInfo[] textFiles = dicInfo.GetFiles("*.*", SearchOption.TopDirectoryOnly);//获取所有目录包含子目录下的文件
        foreach (FileInfo temp in textFiles)
        {
          Console.WriteLine(temp.Name);
        }
      }
      Console.ReadKey();
    }
  }
}
