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 = @"\192.168.1.101c$";  
  
 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();  
    }  
  }  
}
