C#利用WebClient两种方式下载文件

关键词：c#,webclient

WebClient client = new WebClient();
 
第一种
 
string URLAddress = @"http://files.gaodaima.com/x4646/tree.zip";
 
string receivePath=@"C:\";
 
client.DownloadFile(URLAddress, receivePath + System.IO.Path.GetFileName(URLAddress));
 
就OK了。
 
第二种
 
　Stream str = client.OpenRead(URLAddress);
   StreamReader reader = new StreamReader(str);
   byte[] mbyte = new byte[1000000];
   int allmybyte = (int)mbyte.Length;
   int startmbyte = 0;
 
   while (allmybyte > 0)
   {
 
    int m = str.Read(mbyte, startmbyte, allmybyte);
    if (m == 0)
     break;
 
    startmbyte += m;
    allmybyte -= m;
   }
 
   reader.Dispose();
   str.Dispose();
 
   string path = receivePath + System.IO.Path.GetFileName(URLAddress);
   FileStream fstr = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write);
   fstr.Write(mbyte, 0, startmbyte);
   fstr.Flush();
   fstr.Close();
