.net 使用JQuery 调用Ashx 后面直接写方法名，通过反射找到对应的方法

using System.Reflection;

public class Industry_Manager : IHttpHandler

{

    HttpRequest gRequest = null;

    HttpContext gContext = null;

    HttpResponse gResponse = null;

    string func = string.Empty;

    string result = string.Empty;

    string pageUrl = string.Empty;



    public void ProcessRequest(HttpContext context)

    {

        context.Response.ContentType = "text/plain";

        gContext = context;

        gRequest = context.Request;

        gResponse = context.Response;

        func = gRequest["func"];

        MethodInfo method = typeof(Industry_Manager).GetMethod(func);

        if (method != null)

        {

            object[] args = new object[] { result };

            method.Invoke(this, args);

            result = (string)args[0];

        }

        gResponse.Write(result);

    }

js 代码

  url: "http://www.cnblogs.com/Ashx/Industry_Manager.ashx?func=GetIndustryList", //请求数据的页面,后面参数直接跟方法名就可以了，后台通过反射自动查找，并返回数据

 public void GetIndustryList(out string result)

    {

        int count = 0;

        string sort = string.IsNullOrEmpty(gRequest["sort"]) ? "rectime_11022" : gRequest["sort"];

        string order = string.IsNullOrEmpty(gRequest["order"]) ? "desc" : gRequest["order"];

        string sector = gRequest["sector"];

        string name = gRequest["name"];

        string sWhere = "";



        if (!string.IsNullOrEmpty(sector) && sector != "请选择")

        {

            sWhere += " and  f002v_10202='" + sector + "'";

        }



        if (!string.IsNullOrEmpty(name))

        {

            sWhere += " and  f004v_10202 like '" + name + "%'";

        }

        sWhere = sWhere.TrimStart(" and".ToCharArray());

        BLL.vm_dms_allIndustry bll = new BLL.vm_dms_allIndustry();

        List<Model.vm_dms_allIndustry> list = bll.GetListRowNumber("vm_dms_allIndustry", "", sWhere, GetPageIndex(), sort, order, GetPageSize(), "*", "f001g_10202", ref count);

        string strResult = Newtonsoft.Json.JsonConvert.SerializeObject(list);

        strResult = JsonHelper.JsonReplaceDate1(strResult);

        strResult = "{ \"total\":" + count + ",\"rows\":" + strResult + "}";

        result = strResult;

    }

这样就可以避免写一堆 的switch  case 了

类似于这种代码的可以不用写了

public class News_Manager : IHttpHandler

{



    HttpRequest gRequest = null;

    HttpContext gContext = null;

    HttpResponse gResponse = null;

    string func = string.Empty;

    string result = string.Empty;

    string pageUrl = string.Empty;



    public void ProcessRequest(HttpContext context)

    {

        context.Response.ContentType = "text/plain";

        gContext = context;

        gRequest = context.Request;

        gResponse = context.Response;

        pageUrl = gRequest.UrlReferrer.AbsolutePath;      

        func = gRequest["func"];

        if (!string.IsNullOrEmpty(func))

        {

            switch (func)

            {

                case "Get_News_General_List":

                    Get_News_General_List(out result);

                    break;

                case "News_General_Stock_Edit":

                    News_General_Stock_Edit(out result);

                    break;

                case "Get_News_General_ById":

                    Get_News_General_ById(out result);

                    break;

                case "News_General_Stock_Delete":

                    News_General_Stock_Delete(out result);

                    break;

                case "Get_News_General_ByGuid":

                    Get_News_General_ByGuid(out result);

                    break;

                case "News_General_Indus_Edit":

                    News_General_Indus_Edit(out result);

                    break;

                case "News_General_Industry_Delete":

                    News_General_Industry_Delete(out result);

                    break;

                case "Save":

                    Save(out result);

                    break;

                case "GetNewsById":

                    GetNewsById(out result);

                    break;

                case "Get_News_General_Industry_ById":

                    Get_News_General_Industry_ById(out result);

                    break;

                case "CreateGuid":

                    CreateGuid(out result);

                    break;

                case "GetStockByIndustry":

                    GetStockByIndustry(out result);

                    break;

                case "GetPLByNewsIDAndType":

                    GetPLByNewsIDAndType(out result);

                    break;

                default:

                    break;

            }

        }

        gResponse.Write(result);

    }
