datalist button得到了绑定值以后如何传给其他的类？求高手解答！

Question

 
后台：
public void Dlist_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.CommandName == "Delete")
        {
            string getinfoid = e.CommandArgument.ToString();
             response.write(getinfoid); //这里是传给本页！成功
            bool flag = InforBO.GetInstance().delete_infor(getinfoid);  //这里是作为参数传给其他的类！失败
            if (flag == true)
            {
                this.Response.Write("<script>alter('删除成功！！！')</script>");
            }
            
        }
       前台：

Answer 1

InforBO.GetInstance().delete_infor(getinfoid)
这是什么？
是否实例化？
是否是静态类方法？

Answer 2

InforBO.GetInstance()实例化成功了吗？出来的是什么类，报什么异常？

Answer 3

就是getinfoid这个参数传不过去 

Answer 4

你右键delete_infor查看所有引用  看方法里面是如何实现的，在该方法里面加断言调试吧

Answer 5

方法的实现没有问题  我在 bool flag = InforBO.GetInstance().delete_infor(getinfoid)设了一个断点   提示的错误就是参数传不过去 无法提供参数    求帮忙啊！！！
