我有项目,将文件复制到共享网络路径。当我的应用程序验证此路径时,用户也可以使用文件资源管理器访问此文件夹。如何防止用户可以使用文件资源管理器访问此路径而无需用户名和密码提示?我正在使用NetworkCredential类进行身份验证。访问与凭据信息的共享文件夹没有窗口访问

这是我的代码:

class Program 
{ 
    static void Main(string[] args) { 

     string path = @""; 
     string username = ""; 
     string password = ""; 


     try { 
      using (NetworkConnection nc = new NetworkConnection(path, new NetworkCredential(username, password))) { 
       Console.WriteLine("Connected successfully..."); 

       //copy files here ........ 
      } 
     } catch (Exception ex) { 
      Console.WriteLine(ex.Message); 
     } 

     Console.Read(); 
    } 
} 

public class NetworkConnection : IDisposable 
{ 
    string _networkName; 

    public NetworkConnection(string networkName, 
     NetworkCredential credentials) { 
     _networkName = networkName; 

     var netResource = new NetResource() { 
      Scope = ResourceScope.GlobalNetwork, 
      ResourceType = ResourceType.Disk, 
      DisplayType = ResourceDisplaytype.Share, 
      RemoteName = networkName 
     }; 

     var userName = string.IsNullOrEmpty(credentials.Domain) 
      ? credentials.UserName 
      : string.Format(@"{0}\{1}", credentials.Domain, credentials.UserName); 

     var result = WNetAddConnection2(
      netResource, 
      credentials.Password, 
      userName, 
      0); 

     if (result != 0) { 
      throw new Exception("Error connecting to remote share"); 
     } 
    } 

    ~NetworkConnection() { 
     Dispose(false); 
    } 

    public void Dispose() { 
     Dispose(true); 
     GC.SuppressFinalize(this); 
    } 

    protected virtual void Dispose(bool disposing) { 
     WNetCancelConnection2(_networkName, 0, true); 
    } 

    [DllImport("mpr.dll")] 
    private static extern int WNetAddConnection2(NetResource netResource, 
     string password, string username, int flags); 

    [DllImport("mpr.dll")] 
    private static extern int WNetCancelConnection2(string name, int flags, 
     bool force); 
} 

[StructLayout(LayoutKind.Sequential)] 
public class NetResource 
{ 
    public ResourceScope Scope; 
    public ResourceType ResourceType; 
    public ResourceDisplaytype DisplayType; 
    public int Usage; 
    public string LocalName; 
    public string RemoteName; 
    public string Comment; 
    public string Provider; 
} 

public enum ResourceScope : int 
{ 
    Connected = 1, 
    GlobalNetwork, 
    Remembered, 
    Recent, 
    Context 
}; 

public enum ResourceType : int 
{ 
    Any = 0, 
    Disk = 1, 
    Print = 2, 
    Reserved = 8, 
} 

public enum ResourceDisplaytype : int 
{ 
    Generic = 0x0, 
    Domain = 0x01, 
    Server = 0x02, 
    Share = 0x03, 
    File = 0x04, 
    Group = 0x05, 
    Network = 0x06, 
    Root = 0x07, 
    Shareadmin = 0x08, 
    Directory = 0x09, 
    Tree = 0x0a, 
    Ndscontainer = 0x0b 
}

您可以设置连接选项与WNetAddConnection2函数的最后一个参数。这个例子提示用户登录。

var result = WNetAddConnection2(
      netResource, 
      credentials.Password, 
      userName, 
      0x00000008 | 0x00000010); 

0x00000008 =如果该标志被设置时,操作系统可以与用户为了认证目的交互。

0x00000010 =此标志指示系统不使用用户名或密码的任何默认设置,也不提供用户提供替代品的机会。除非CONNECT_INTERACTIVE也被设置,否则该标志被忽略。

如果应用程序以不同的 用户运行,则也可以使用此标志。

0x00000004 =网络资源连接不应该被记住。如果设置了此标志,则当用户再次登录时,操作系统不会尝试恢复连接。

或者组合这些标志

0x00002000 =如果这个标志设置,并且操作系统会提示输入凭证,凭证是由凭证管理器复位。除非设置了CONNECT_COMMANDLINE标志,否则该标志将被忽略。

0x00000800 =如果设置了此标志,则操作系统将使用命令行而不是图形用户界面(GUI)提示用户进行认证。除非CONNECT_INTERACTIVE也被设置,否则该标志被忽略。
