使用WebBrowser自动登录阿里妈妈网站

窗体上放一个WebBrowser，其Url属性设置为http://www.alimama.com/membersvc/member/login.htm，其他属性为默认

再放一个Button，默认

Button按钮的代码如下（方法一）

view plaincopy to clipboardprint?
private void button1_Click( object sender, EventArgs e )   
{   
    System.Windows.Forms.HtmlDocument document =this.webBrowser1.Document;   
    if ( document == null )   
    {   
        return;   
    }   
    document.All["logname"].SetAttribute( "Value", "用户名" );            //用户名   
    document.All["originalLogpasswd"].SetAttribute( "Value", "密码" );      //密码   
    document.All["dologin"].InvokeMember( "click" );    //登录按钮的click方法         
}  
        private void button1_Click( object sender, EventArgs e )
        {
            System.Windows.Forms.HtmlDocument document =this.webBrowser1.Document;
            if ( document == null )
            {
                return;
            }
            document.All["logname"].SetAttribute( "Value", "用户名" );            //用户名
            document.All["originalLogpasswd"].SetAttribute( "Value", "密码" );      //密码
            document.All["dologin"].InvokeMember( "click" );    //登录按钮的click方法      
        }

方法二

view plaincopy to clipboardprint?
private void button1_Click( object sender, EventArgs e )   
{   
    System.Windows.Forms.HtmlDocument document =this.webBrowser1.Document;   
    if ( document == null )   
    {   
        return;   
    }   
    document.All["logname"].SetAttribute( "Value", "用户名" );            //用户名   
    document.All["originalLogpasswd"].SetAttribute( "Value", "密码" );      //密码   
  
    document.All["dologin"].RaiseEvent( "onClick" );        //登录按钮的click事件   
    document.All["formRegStep1Main"].InvokeMember( "submit" );  //提交表单   
}  
        private void button1_Click( object sender, EventArgs e )
        {
            System.Windows.Forms.HtmlDocument document =this.webBrowser1.Document;
            if ( document == null )
            {
                return;
            }
            document.All["logname"].SetAttribute( "Value", "用户名" );            //用户名
            document.All["originalLogpasswd"].SetAttribute( "Value", "密码" );      //密码
      
            document.All["dologin"].RaiseEvent( "onClick" );        //登录按钮的click事件
            document.All["formRegStep1Main"].InvokeMember( "submit" );  //提交表单
        }
