写个多线程，调用webClient.DownloadFile()，就好了。
我有代码，回家找找看。

加
using System.Net;

    public void GetFileFromUrl(string FromUrl, string toPath)

    {

        WebClient webClient = new WebClient();

        Uri uri = new Uri(FromUrl);

        webClient.DownloadFile(uri, toPath);

        webClient.Dispose();

    }

mark

顶...
