  1.   

    察看button1_Click实践是否注册了,简单的方法就是双击Button1 让其自动生成事件。
    根据你的实际开发情况,考虑是否可以将Page_load事件修改为
       private void SanGuo_Load(object sender, EventArgs e) 
            { 
               if (!IsPostBack)            {
                webBrowser1.Navigate("http://s1.sanguo.yeeyoo.com"); 
                }
            }
