处理页：
1.得到List列表
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string result = "";
string Title = context.Request["page"]; string a = Title;
if (a == "")
{
IList<QuestionModel> Infos = new QuestionBLL().GetModelList(" id<10 ");
result = JsonConvert.SerializeObject(Infos);
}
else
{
IList<QuestionModel> Infos = new QuestionBLL().GetModelList("id>9 and id<100 ");
result = JsonConvert.SerializeObject(Infos);
}
//总记录数total
//构造json
result = "{\"total\":100,\"rows\":"+result+"}";
context.Response.Write(result);
}
2.增加修改删除

using System.Linq;

using Wzh.BLL;
using Wzh.Model;

{
