我有項目,將文件複製到共享網絡路徑。當我的應用程序驗證此路徑時,用戶也可以使用文件資源管理器訪問此文件夾。如何防止用戶可以使用文件資源管理器訪問此路徑而無需用戶名和密碼提示?我正在使用NetworkCredential類進行身份驗證。訪問與憑據信息的共享文件夾沒有窗口訪問

這是我的代碼:

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 
}

您可以設置連接選項與WNetAddConnection2函數的最後一個參數。這個例子提示用戶登錄。

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

0x00000008 =如果該標誌被設置時,操作系統可以與用戶爲了認證目的交互。

0x00000010 =此標誌指示系統不使用用戶名或密碼的任何默認設置,也不提供用戶提供替代品的機會。除非CONNECT_INTERACTIVE也被設置,否則該標誌被忽略。

如果應用程序以不同的 用戶運行,則也可以使用此標誌。

0x00000004 =網絡資源連接不應該被記住。如果設置了此標誌,則當用戶再次登錄時,操作系統不會嘗試恢復連接。

或者組合這些標誌

0x00002000 =如果這個標誌設置,並且操作系統會提示輸入憑證,憑證是由憑證管理器復位。除非設置了CONNECT_COMMANDLINE標誌,否則該標誌將被忽略。

0x00000800 =如果設置了此標誌,則操作系統將使用命令行而不是圖形用戶界面(GUI)提示用戶進行認證。除非CONNECT_INTERACTIVE也被設置,否則該標誌被忽略。
