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();  
    }  
  }  
}
