C#一个下载类，支持断点下载，多线程之类的

可能一下代码会比较长，看起来比较麻烦，我大概说一下用法，这个类我自己测试过是没有问题的

代码

1 Download load = new Download(dr["SourceUrl"].ToString());
2 load.ThreadCount = 5;
3 load.Filename = dr["FileName"].ToString();
4 load.DirectoryName = dr["Dest"].ToString();
5 load.Progress += new Download.ProgressEventHandler(load_Progress);
6 load.Finished += new Download.FinishedEventHandler(load_Finished);
7 load.Speed += new Download.SpeedHandler(load_Speed);
8 load.Start();

下面是全部代码

Download

  1 public class Download
  2     {
  3         public Download(string url)
  4         {
  5             this.Url = url;
  6             this.ThreadCount = 5;
  7         }

11         public delegate void ExceptionEventHandler(Download sender, Exception e);
12         public delegate void ConnectedEventHandler(Download sender, string filename, string contentType);
13         public delegate void ProgressEventHandler(Download
