asp.net-mvc - 为什么 ASP.NET MVC 路径会出现变量？

Question

在我的 MVC 应用程序中，为什么

Return RedirectToAction("Edit", "Forms", New With {.member = "123"})

返回

http://localhost:13/Forms/Edit?member=123

代替

http://localhost:13/Forms/Edit/123

?

为什么

<%=Html.ActionLink("MyLink", "Edit", "Forms", New With {.member = "123"}, Nothing)%>

做同样的事情？

正如 tvanfosson 所说，“id”是默认路由引擎设置为查找的内容。任何其他作为第三个参数的东西，它都会被当作查询字符串。

为什么？由于 Global.asax 中的这种方法:

routes.MapRoute(
    "Default",
    "{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = "" }
);

您可以通过添加额外的 routes.MapRoute() 行来更改此设置，如下所示:

routes.MapRoute(
    "Default",
    "{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = "" }
);

routes.MapRoute(
    "Default2",
    "{controller}/{action}/{member}",
    new { controller = "Home", action = "Index", member = "" }
);
