如何将文件夹复制到一个目录?

如何将文件夹复制到目录?

我几乎什么都试过了，但就是不行。

我从其他问题中得到了例子，但没有一个是有效的。

当我试图让我的应用程序复制一个文件夹时，它给了我一个错误:

File does not exist: C:'Users'Loko'Desktop'dir1'New folder (5)

在这一行:

Stopwatch stopwatch = Stopwatch.StartNew();

这可能与它无关。不管怎样，有人能帮我吗?只是文件夹出了点问题。

这是我的代码:

    using System;
    using System.IO;
    using System.Configuration;
    using System.Collections.Generic;

    using MySql.Data.MySqlClient;
    namespace ChaloSync
    {
    public partial class Form1 : Form
    {
        private bool pause = false;
        String source = ConfigurationManager.AppSettings[@"Directory1"];
        String target = ConfigurationManager.AppSettings[@"Directory2"];

        public static bool WaitForFileAvailable(string filePath, TimeSpan timeout)
        {
            if (!File.Exists(filePath))
                throw new InvalidOperationException("File does not exist: " + filePath);
            Stopwatch stopwatch = Stopwatch.StartNew();
            while (stopwatch.Elapsed <= timeout)
            {
                try
                {
                    using (new FileStream(filePath, FileMode.Open, FileAccess.Read))
                    {
                        return true;
                    }
                }
                catch { }
                Thread.Sleep(250);
            }
            return false;
        }

            }
            else // The file failed to become available within 10 seconds.
            {
                // Error handling.
            }
            }

        }

                Start.Text = "Pause";
