我是说.cs的文件，不是.aspx.cs的文件，在这里面Response不好用，请问怎样才能弹出提示框呢
------解决方案--------------------------------------------------------
System.Web.HttpContext.Current.Response.Write("<script>alert('sss');</script>");
------解决方案--------------------------------------------------------
- C# code
HttpContext.Current.Response.Write("<script>alert('asdaksdjlaksd');location.href=location.href</script>");//要这样子的不?

给你个类~
- C# code
using System;using System.Text;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 Show(System.Web.UI.Page page, string msg) { page.RegisterStartupScript("message", "<script language='javascript' defer>alert('" + msg.ToString() + "');</script>"); } /// <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) { StringBuilder Builder = new StringBuilder(); Builder.Append("<script language='javascript' defer>"); Builder.AppendFormat("alert('{0}');", msg); Builder.AppendFormat("location.href='{0}'", url); Builder.Append("</script>"); page.RegisterStartupScript("message", Builder.ToString()); } public static void ShowAndRedirect(System.Web.UI.Page page, string msg, string url, bool top) { StringBuilder Builder = new StringBuilder(); Builder.Append("<script language='javascript' defer>"); Builder.AppendFormat("alert('{0}');", msg); if (top == true) { Builder.AppendFormat("top.location.href='{0}'", url); } else { Builder.AppendFormat("location.href='{0}'", url); } Builder.Append("</script>"); page.RegisterStartupScript("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.RegisterStartupScript("message", "<script language='javascript' defer>" + script + "</script>"); }}
------解决方案--------------------------------------------------------
那是因为类里面缺少引用 using System.Web.HttpContext.Current；
或者直接这么写
System.Web.HttpContext.Current.Response.Write("<script>alert('提示');</script>");
