看不明白啊，有没有System.Net里面的实现方法？

Dim mywebclient As New WebClient
Dim i As Integer
mywebclient.DownloadFile("http://image2.sina.com.cn/home/images/sina_logo2.gif", "d:\down\sina_logo2.gif")
Messagebox.show("下载完成","")

[wsxcy66668888]

Imports System.Net

Dim mywebclient As New WebClient
mywebclient.DownloadFile("http://image2.sina.com.cn/home/images/sina_logo2.gif", "d:\down\sina_logo2.gif")
Messagebox.show("下载完成","")

}
catch(Exception ex)
{
Console.WriteLine(ex.Message);
}
}
}
}

以前写了测试测试的。
