另一种选择是您可以以编程方式访问NET USEwindows 的 api 并对共享进行身份验证，就像您在资源管理器中访问它并输入凭证一样。

你使用它就像
DisconnectFromShare(@"\\server-a\DBFiles", true); //Disconnect in case we are currently connected with our credentials;
ConnectToShare(@"\\server-a\DBFiles", username, password); //Connect with the new credentials
if (!Directory.Exists(@"\\server-a\DBFiles\"))

File.Copy("C:\Temp\abc.txt", @"\\server-a\DBFiles\");
DisconnectFromShare(@"\\server-a\DBFiles", false); //Disconnect from the server.
