Respose.Write("<script     language='javascript'>window.open('"+     url     +"');</script>"); （打开简洁窗口）：
Respose.Write("<script     language='javascript'>window.open('"     +     url     +     "','','resizable=1,scrollbars=0,status=1,menubar=no,toolbar=no,location=no,     menu=no');</script>");

1. Response.Redirect("XXX.aspx",true)——直接转向新的页面，原窗口被代替;
2. Response.Write("<script>window.open('XXX.aspx','_blank')</script>")——原窗口保留，另外新增一个新页面;
3. Response.Write("<script>window.location='XXX.aspx'</script>")——打开新的页面，原窗口被代替;
4. Server.Transfer("XXX.aspx")——打开新的页面;
5. Response.Write("<script>window.showModelessDialog('XXX.aspx')</script>")——原窗口保留，以对话框形式打开新窗口;
6. Response.Write("<script>window.showModelDialog('XXX.aspx')</script>")——对话框形式打开新窗口，原窗口被代替;
也可以自己写方法：

复制代码代码如下:

public static void ShowMessage(System.Web.UI.Page page, string msg)
{
    page.ClientScript.RegisterClientScriptBlock(page.GetType(), "a", "alert('" + msg.ToString() + "');", true);
}

调用的时候：
ShowMessage(this,"要显示的消息");
下面是整个类的代码你可以挑着用

复制代码代码如下:

using System;
using System.Collections.Generic;
using System.Text;
namespace WorkLogic
{
    /// <summary>
    /// 显示消息提示对话框。
    /// </summary>
    public class MessageBox
    {
        private MessageBox()
        {
        }
        /// <summary>
        /// 显示消息提示对话框
        /// </summary>
        /// <param name="page">当前页面指针，一般为this</param>
        /// <param name="msg">提示信息</param>
        public static void ShowMessage(System.Web.UI.Page page, string msg)
        {
            //page.RegisterStartupScript("message", "alert('" + msg.ToString() + "');");
            page.ClientScript.RegisterClientScriptBlock(page.GetType(), "a", "alert('" + msg.ToString() + "');", true);
        }
        public static void ShowMessage(System.Web.UI.UserControl control, string msg)
        {
            control.Page.ClientScript.RegisterClientScriptBlock(control.Page.GetType(), "b", "alert('" + msg.ToString() + "');", true);
        }
        /// <summary>
        /// 控件点击 消息确认提示框
        /// </summary>
        /// <param name="page">当前页面指针，一般为this</param>
        /// <param name="msg">提示信息</param>
        public static void ShowConfirm(System.Web.UI.WebControls.WebControl Control, string msg)
        {
            //Control.Attributes.Add("onClick","if (!window.confirm('"+msg+"')){return false;}");
            Control.Attributes.Add("onclick", "return confirm('" + msg + "');");
        }
        /// <summary>
        /// 显示消息提示对话框，并进行页面跳转
        /// </summary>
        /// <param name="page">当前页面指针，一般为this</param>
        /// <param name="msg">提示信息</param>
        /// <param name="url">跳转的目标URL</param>
        public static void ShowAndRedirect(System.Web.UI.Page page, string msg, string url, string frame)
        {
            StringBuilder Builder = new StringBuilder();
            Builder.Append("<script language='javascript' defer>");
            Builder.AppendFormat("alert('{0}');", msg);
            Builder.AppendFormat("top." + frame + ".location.href='{0}'", url);
            Builder.Append("</script>");
            page.ClientScript.RegisterStartupScript(page.GetType(), "message", Builder.ToString());
        }
        /// <summary>
        /// 输出自定义脚本信息
        /// </summary>
        /// <param name="page">当前页面指针，一般为this</param>
        /// <param name="script">输出脚本</param>
        public static void ResponseScript(System.Web.UI.Page page, string script)
        {
            page.ClientScript.RegisterStartupScript(page.GetType(), "message", "<script language='javascript' defer>" + script + "</script>");
        }
        /// <summary>
        /// 显示消息提示对话框，并进行页面跳转
        /// <param name="page">当前页面指针，一般为this</param>
        /// <param name="msg">提示信息</param>
        /// <param name="url">跳转的目标URL</param>
        public static void ShowAndRedirect(System.Web.UI.Page page, string msg, string url)
        {
            StringBuilder Builder = new StringBuilder();
            Builder.Append("<script language='javascript' defer>");
            Builder.AppendFormat("alert('{0}');", msg);
            Builder.AppendFormat("top.location.href='{0}'", url);
            Builder.Append("</script>");
            page.ClientScript.RegisterStartupScript(page.GetType(), "message", Builder.ToString());
       }
}
