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);
