一般处理程序代码：
using System;
using System.Web;
using Ajax无刷新删除.DataSetDeleteDataTableAdapters;
namespace Ajax无刷新删除
{
/// <summary>
/// DeleteDataById 的摘要说明
/// </summary>
public class DeleteDataById : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
int id = Convert.ToInt32(context.Request["id"]);
new T_CommentTableAdapter().DeleteDataById(id);
}
public bool IsReusable
{
get
{
return false;
}
}
}
