asp.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);
