将程序文件夹复制并粘贴到映射的网络驱动器中

我正在尝试在映射的网络驱动器上复制文件夹（不是文件而是整个目录），并在同一位置粘贴其新版本的不同名称。 如果我使用本地驱动器，下面的代码很有用; 但是，使用网络驱动器时出现身份validation错误。

DirectoryCopy(@"\\mappedserver\test", @"\\mappedserver\test2", true); 

“mscorlib.dll中发生了’System.IO.IOException’类型的未处理exception

附加信息：用户名或密码不正确。“

我使用了以下MSDN文档： 链接并稍微修改它以满足我的需要。

  private static void DirectoryCopy( string sourceDirName, string destDirName, bool copySubDirs) { DirectoryInfo dir = new DirectoryInfo(sourceDirName); DirectoryInfo[] dirs = dir.GetDirectories(); // If the source directory does not exist, throw an exception. if (!dir.Exists) { throw new DirectoryNotFoundException( "Source directory does not exist or could not be found: " + sourceDirName); } // If the destination directory does not exist, create it. if (!Directory.Exists(destDirName)) { Directory.CreateDirectory(destDirName); } // Get the file contents of the directory to copy. FileInfo[] files = dir.GetFiles(); foreach (FileInfo file in files) { // Create the path to the new copy of the file. string temppath = Path.Combine(destDirName, file.Name); // Copy the file. file.CopyTo(temppath, false); } // If copySubDirs is true, copy the subdirectories. if (copySubDirs) { foreach (DirectoryInfo subdir in dirs) { // Create the subdirectory. string temppath = Path.Combine(destDirName, subdir.Name); // Copy the subdirectories. DirectoryCopy(subdir.FullName, temppath, copySubDirs); } } } 

一个流行的解决方案似乎是给文件夹完全访问权限，但不幸的是，这没有什么区别。

我如何提供用户名和密码？ 我真的不想在应用程序的任何地方放置管理员用户名和密码，这样做怎么办？ 我的搜索大多是空的。

一旦我需要从远程PC复制文件。 我找到了这堂课：

当您拥有凭据时，它将帮助您连接远程PC。 你可以使用它：

  using (NetworkShareAccesser.Access("1.1.1.1","domain","login","password")) { //Here you have access to remote pc and you can perform your actions } 

希望这是你正在寻找的。
