ASP.NET中的几种弹出框提示基本实现方法

using System; 
using System.Web; 
namespace ShowMessage 
{ 
/// <summary> 
/// Msg 的摘要说明。 
/// </summary> 
public class ShowMessage 
{ 
public ShowMessage() 
{ 
// 
// TODO: 在此处添加构造函数逻辑 
// 
} 
public static void ShowMessage(string strMsg) 
{ 
System.Web.HttpContext.Current.Response.Write("<Script Language='JavaScript'>window.alert('"+strMsg+"');</script>"); 
} 
public static void ShowMessage(System.Web.UI.Page page, string strMsg) 
{ 
page.Response.Write("<Script Language='JavaScript'>window.alert('"+strMsg+"');</script>"); 
} 
public static void ShowMessage( string strMsg, string Url) 
{ 
System.Web.HttpContext.Current.Response.Write("<Script Language='JavaScript'>window.alert('"+strMsg+"');window.location.href='"+Url+"'</script>"); 
} 
public static void ShowMessage( System.Web.UI.Page page,string strMsg, string Url) 
{ 
page.Response.Write("<Script Language='JavaScript'>window.alert('"+strMsg+"');window.location.href='"+Url+"'</script>"); 
} 
public static void ShowConfirm(string strMsg, string strUrl_Yes, string strUrl_No) 
{ 
System.Web.HttpContext.Current.Response.Write("<Script Language='JavaScript'>if ( window.confirm('"+strMsg+"')) { window.location.href='" + strUrl_Yes + 
"' } else {window.location.href='"+ strUrl_No +"' };</script>"); 
} 
} 
}
