待研究的代码

public void MessageBox(string Message, System.Web.UI.Page page, bool IsClose)
        {
            Type cstype = page.GetType();
            if (IsClose)
            {
                page.ClientScript.RegisterStartupScript(cstype, "MessageBox", string.Format("<script>alert('{0}');top.window.opener=null;top.window.close();</script>", Message));
            }
            else
            {
                page.ClientScript.RegisterStartupScript(cstype, "MessageBox", string.Format("<script>alert('{0}');</script>", Message));
            }
        }
