土司论坛看到的,测试了一下很好用,以后下载工具资料什么的就方便了

代码如下

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.IO;
using System.Text.RegularExpressions; 
namespace csdn
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        public void getpage()
        {
            string  Url = downurl.Text;
            string[] sun = Url.Split('/');
            string id = sun[sun.Length - 1];
            WebClient Client = new WebClient();
            Client.Credentials = CredentialCache.DefaultCredentials;
            byte[] PageData = Client.DownloadData(@Url);
            string data = Encoding.UTF8.GetString(PageData);
            int a = data.IndexOf("http:\\/\\/");
            int b=data.IndexOf("\"}");
            string temp=data.Substring(a,b-a);
            temp = temp.Replace("\\""");
            webBrowser1.Navigate(temp);
         
          
        }
        private void button1_Click(object sender, EventArgs e)
        {
            getpage();
        }
    }
}
