c# - JavaScript:来自 ASP.NET 代码隐藏的 Alert.Show(message)

Question

我正在读这个JavaScript: Alert.Show(message) From ASP.NET Code-behind

我正在尝试实现相同的功能。所以我创建了一个这样的静态类:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data;
using System.Data.SqlClient;
using System.Web;
using System.Text;
using System.Web.UI;

namespace Registration.DataAccess
{
    public static class Repository
    {
        /// <summary> 
        /// Shows a client-side JavaScript alert in the browser. 
        /// </summary> 
        /// <param name="message">The message to appear in the alert.</param> 
        public static void Show(string message) 
            { 
               // Cleans the message to allow single quotation marks 
               string cleanMessage = message.Replace("'", "\'"); 
               string script = "<script type="text/javascript">alert('" + cleanMessage + "');</script>"; 

               // Gets the executing web page 
               Page page = HttpContext.Current.CurrentHandler as Page; 

               // Checks if the handler is a Page and that the script isn't allready on the Page 
               if (page != null && !page.ClientScript.IsClientScriptBlockRegistered("alert")) 
               { 
                 page.ClientScript.RegisterClientScriptBlock(typeof(Alert), "alert", script); 
               } 
            } 
    }
}

在这一行:

string script = "<script type="text/javascript">alert('" + cleanMessage + "');</script>"; 

它向我显示错误:；预计

还有在

page.ClientScript.RegisterClientScriptBlock(typeof(Alert), "alert", script); 

错误:找不到类型或命名空间名称“Alert”(是否缺少 using 指令或程序集引用？)

我在这里做错了什么？

这里有一个简单的方法:

Response.Write("<script>alert('Hello');</script>");
