C#学习教程:从C#访问远程目录分享


从C#访问远程目录

我试图从asp.net中的C#程序访问远程网络共享。 我需要的是类似的东西

function download(dirname) { directory = (This is the part I don't know how to do) for dir in directory: download(dir); for file in directory: copyfile(file); } 

我的问题是该目录需要用户名和密码才能访问,我不知道如何提供它们。 谢谢你尽你所能的帮助。

使用此类进行身份validation,而不仅仅是使用简单的文件操作:

 ///  /// Represents a network connection along with authentication to a network share. ///  public class NetworkConnection : IDisposable { #region Variables ///  /// The full path of the directory. ///  private readonly string _networkName; #endregion #region Constructors ///  /// Initializes a new instance of the  class. ///  ///  /// The full path of the network share. ///  ///  /// The credentials to use when connecting to the network share. ///  public NetworkConnection(string networkName, NetworkCredential credentials) { _networkName = networkName; var netResource = new NetResource { Scope = ResourceScope.GlobalNetwork, ResourceType = ResourceType.Disk, DisplayType = ResourceDisplaytype.Share, RemoteName = networkName.TrimEnd('\') }; var result = WNetAddConnection2( netResource, credentials.Password, credentials.UserName, 0); if (result != 0) { throw new Win32Exception(result); } } #endregion #region Events ///  /// Occurs when this instance has been disposed. ///  public event EventHandler Disposed; #endregion #region Public methods ///  /// Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. ///  public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } #endregion #region Protected methods ///  /// Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. ///  /// true to release both managed and unmanaged resources; false to release only unmanaged resources. protected virtual void Dispose(bool disposing) { if (disposing) { var handler = Disposed; if (handler != null) handler(this, EventArgs.Empty); } WNetCancelConnection2(_networkName, 0, true); } #endregion #region Private static methods ///  ///The WNetAddConnection2 function makes a connection to a network resource.

用法:

 using(new NetworkConnection(_directoryPath, new NetworkCredential(_userName, _password))) { File.Copy(localPath, _directoryPath); } 

你需要冒充用户看到这个问题

有效地,您需要调用登录来创建可用于访问文件系统的Windows标识
