App_Code下的类中运用ClientScriptManager弹出窗口解决方法

App_Code下的类中运用ClientScriptManager弹出窗口

C# code

public class Class1 : System.Web.UI.Page{    public Class1()    {    }    public void aa(string strMessage)    {        ClientScriptManager cs = Page.ClientScript;        Type cstype = this.GetType();        string csstring = "PopupScript";        string cstext = "alert('" + strMessage + "');";        cs.RegisterStartupScript(cstype, csstring, cstext, true);    }}

如上边的代码，我想将alert("....")写到一个类中然后再某些页面需要探出提示窗口的时候直接调用，但是在执行的时候没有出现问题，只是不会出现么messagebox
我想请问一下是不是Page.ClientScript的问题，个位帮忙解答一下！

[解决办法]
类a
public static void Alert(string str, Page page)
{
str = Regex.Replace(str,"['|\r|\n]*", "");
page.ClientScript.RegisterStartupScript(page.GetType(), "alert", string.Format("alert(\"{0}\")", str), true);
}
调用:
a.Alert("xxx", Page);
[解决办法]
this.Page.RegisterStartupScript("alert", "<script language=javascript>alert('" + strMessage + "');</script>");
用这个 传一个page对象进去试试
我没用 只是猜想

C# code

public class Class1{    public Class1()    {    }    public void aa(string strMessage)    {        Page page = (Page)System.Web.HttpContext.Current.Handler;        ClientScriptManager cs = page.ClientScript;        Type cstype = this.GetType();        string csstring = "PopupScript";        string cstext = "alert('" + strMessage + "');";        cs.RegisterStartupScript(cstype, csstring, cstext, true);    }}
[解决办法]
C# code
        /// <summary>        /// 警告框        /// </summary>        /// <param name="_Msg">警告字串</param>        /// <param name="_Page">this</param>        /// <returns>警告框JS</returns>        public static object Alert(string _Msg, Page _Page)        {            string StrScript;            StrScript = ("<script language=javascript>");            StrScript += ("alert('" + _Msg + "');");            StrScript += ("</script>");            _Page.ClientScript.RegisterStartupScript(_Page.GetType(), "MsgBox", StrScript.ToString());            return StrScript;        }
[解决办法]
C# code
public void aa(string strMessage)    {         string cstext = "alert('" + strMessage + "');";         ((Page)HttpContext.Current.Handler).ClientScript.RegisterStartupScript(this.GetType(), Guid.NewGuid().ToString(), cstext, true);    }
