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

bubuko.com,布布扣
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);
