  这个是类

 

调用的时候：  
   
  NetResource   nr;  
  nr.dwDisplayType=ResourceDisplayType.RESOURCEDISPLAYTYPE_GENERIC;  
  nr.dwScope=ResourceEnumerationScope.RESOURCE_GLOBALNET;  
  nr.dwType=ResourceType.RESOURCETYPE_DISK;  
  nr.dwUsage=ResourceUsage.RESOURCEUSAGE_CONNECTABLE;  
  nr.lpComment="";  
  nr.lpLocalName="z:";  
  nr.lpProvider="";  
  nr.lpRemoteName=@"//192.168.1.126/XingDong";  
   
  if(CopyFileByNet.WNetAddConnection2(ref   nr,"密码","用户名",ConnectionOption.CONNECT_INTERACTIVE)==WNetAddConnection2ReturnCode.NO_ERROR)  
  {  
  MessageBox.Show("mapped   succeed");  
  }  
  else  
  {  
  MessageBox.Show("mapped   failure");  
  }  
   
  if(CopyFileByNet.WNetCancelConnection2("z:",0,true)==WNetCancelConnection2ReturnCode.NO_ERROR)  
  {  
  MessageBox.Show("cancel   succeed");  
  }  
  else  
  {  
  MessageBox.Show("cancel   error");  
  }  
  在映射后可以访问电脑A
