C#访问网络共享文件夹的方法

本文实例为大家分享了c#访问网络共享文件夹的具体代码，供大家参考，具体内容如下

using system.runtime.interopservices; 
 
public enum error_id 
 { 
  error_success = 0, // success 
  error_busy = 170, 
  error_more_data = 234, 
  error_no_browser_servers_found = 6118, 
  error_invalid_level = 124, 
  error_access_denied = 5, 
  error_invalid_password = 86, 
  error_invalid_parameter = 87, 
  error_bad_dev_type = 66, 
  error_not_enough_memory = 8, 
  error_network_busy = 54, 
  error_bad_netpath = 53, 
  error_no_network = 1222, 
  error_invalid_handle_state = 1609, 
  error_extended_error = 1208, 
  error_device_already_remembered = 1202, 
  error_no_net_or_bad_path = 1203 
 } 
 
 public enum resource_scope 
 { 
  resource_connected = 1, 
  resource_globalnet = 2, 
  resource_remembered = 3, 
  resource_recent = 4, 
  resource_context = 5 
 } 
 
 public enum resource_type 
 { 
  resourcetype_any = 0, 
  resourcetype_disk = 1, 
  resourcetype_print = 2, 
  resourcetype_reserved = 8, 
 } 
 
 public enum resource_usage 
 { 
  resourceusage_connectable = 1, 
  resourceusage_container = 2, 
  resourceusage_nolocaldevice = 4, 
  resourceusage_sibling = 8, 
  resourceusage_attached = 16, 
  resourceusage_all = (resourceusage_connectable | resourceusage_container | resourceusage_attached), 
 }

  resourcedisplaytype_file = 4, 
  resourcedisplaytype_group = 5, 
  resourcedisplaytype_network = 6, 
  resourcedisplaytype_root = 7, 
  resourcedisplaytype_shareadmin = 8, 
  resourcedisplaytype_directory = 9, 
  resourcedisplaytype_tree = 10,

 } 
 
 [structlayout(layoutkind.sequential)] 
 public struct netresource 
 { 
  public resource_scope dwscope; 
  public resource_type dwtype; 
  public resource_displaytype dwdisplaytype; 
  public resource_usage dwusage; 
 
  [marshalas(unmanagedtype.lpstr)] 
  public string lplocalname; 
 
  [marshalas(unmanagedtype.lpstr)] 
  public string lpremotename; 
 
  [marshalas(unmanagedtype.lpstr)] 
  public string lpcomment; 
 
  [marshalas(unmanagedtype.lpstr)] 
  public string lpprovider; 
 } 
 
 public class networkconnection 
 { 
 
  [dllimport("mpr.dll")] 
  public static extern int wnetaddconnection2a(netresource[] lpnetresource, string lppassword, string lpusername, int dwflags); 
 
  [dllimport("mpr.dll")] 
  public static extern int wnetcancelconnection2a(string sharename, int dwflags, int fforce); 
 
 
  public static int connect(string remotepath, string localpath, string username, string password) 
  { 
   netresource[] share_driver = new netresource[1]; 
   share_driver[0].dwscope = resource_scope.resource_globalnet; 
   share_driver[0].dwtype = resource_type.resourcetype_disk; 
   share_driver[0].dwdisplaytype = resource_displaytype.resourcedisplaytype_share; 
   share_driver[0].dwusage = resource_usage.resourceusage_connectable; 
   share_driver[0].lplocalname = localpath; 
   share_driver[0].lpremotename = remotepath; 
 
   disconnect(localpath); 
   int ret = wnetaddconnection2a(share_driver, password, username, 1); 
 
   return ret; 
  } 
 
  public static int disconnect(string localpath) 
  { 
   return wnetcancelconnection2a(localpath, 1, 1); 
  } 
 
} 

测试方法：

public void testnetworkconnection() 
  { 
   string localpath = "x:"; 
   //int status = networkconnection.connect(@"//192.168.0.2/test", localpath, @"test", "test"); 
   int status = networkconnection.connect("////192.168.0.2//test", localpath, @"test", "test"); 
   if (status == (int)error_id.error_success) 
   { 
    filestream fs = new filestream(localpath + @"//123.txt", filemode.openorcreate); 
    using (streamwriter stream = new streamwriter(fs)) 
    { 
     stream.writeline("你好呀，成功了"); 
     stream.flush(); 
     stream.close(); 
    } 
    fs.close(); 
   } 
   else 
   { 
    console.writeline(status); 
   } 
   networkconnection.disconnect(localpath); 
  }
