小5聊C# 遵守路由设置规则，否则报错

Posted 2022-11-23 小5聊

1、路由设置

public class RouteConfig

    public static void RegisterRoutes(RouteCollection routes)
    
        routes.IgnoreRoute("resource.axd/*pathInfo");

        routes.MapRoute(
            name: "Default",
            url: "controller/action/id",
            defaults: new  controller = "Home", action = "Index", id = UrlParameter.Optional ,
            namespaces: new[]  "Test.Controllers" 
        );
    

2、请求地址

假设请求地址为：/Area/Test/List/123

3、错误写法

不能直接使用TestID来接受参数

public async Task<ActionResult> TestItem(int TestID)

    return View();

4、正确写法

public async Task<ActionResult> TestItem(int id)

    int TestID = id;
    return View();
