推荐答案

使用 System.IO.File 和 System.IO.Directory classes。

Eg

Use the System.IO.File and System.IO.Directory classes.
E.g.

string[] files = System.IO.Directory.GetFiles(sourcePath);

// Copy the files and overwrite destination files if they already exist.
foreach (string s in files)
{
    // Use static Path methods to extract only the file name from the path.
    fileName = System.IO.Path.GetFileName(s);
    destFile = System.IO.Path.Combine(targetPath, fileName);
    System.IO.File.Copy(s, destFile, true);
}

private void CopyFolder(string sourcePath, string DestPath, bool overWrite)
{
     DirectoryInfo dir = new DirectoryInfo(sourcePath);

     //iterate through all files
     foreach (FileInfo file in dir.GetFiles())
     {
           file.CopyTo(DestPath  + file.Name, overWrite);
     }
}

注意：处理一些可能的错误，如文件夹存在，路径格式等。

Note: Handle some possible errors by own like folder exists, path formats etc.

您需要使用模拟用户。使用该模拟用户，您将复制到第二台计算机

You need to use an Impersonated User. With that impersonated user you acn copy to the second machine

IntPtr admin_token = default(IntPtr);
                        IntPtr dupToken = default(IntPtr);

                        WindowsIdentity wid_current = WindowsIdentity.GetCurrent();
                        WindowsIdentity wid_admin = null;
                        WindowsImpersonationContext wic = null;
                        string[] split = new string[1];
                        split[0] = "\\";
                        string[] temp = ServerName.Split(split, StringSplitOptions.RemoveEmptyEntries);
                        string domain = String.Empty;
                        string userName = ServerUserName;
                        string password = Password;
                        if (LogonUser(userName, domain, password, LOGON32_LOGON_NEW_CREDENTIALS, LOGON32_PROVIDER_DEFAULT, ref admin_token) != 0)
                        {
                            if (DuplicateToken(admin_token, 2, out dupToken))
                            {
                                wid_admin = new WindowsIdentity(dupToken);
                                wic = wid_admin.Impersonate();
                                try
                                {
                                    // File.COPY thing
                                }
                                finally
                                {
                                    if (wic != null)
                                    {
                                        wic.Undo();
                                    }
                                    if (admin_token != default(IntPtr))
                                        CloseHandle(admin_token);

                                    if (dupToken != default(IntPtr))
                                        CloseHandle(dupToken);                             
                                }
                           }
