Asp.net MVC學習筆記3----Route的限制

假如在Gloable.ascx文件中定義瞭如下的Route,

 

 routes.MapRoute( "Product", "Product/{productId}", new {controller="Product", action="Details"} ); using System.Web.Mvc; namespace MvcApplication1.Controllers { public class ProductController : Controller { public ActionResult Details(int productId) { return View(); } } }

 

如果輸入的參數不能轉化整形的話，就會出錯，

 

The route defined in Listing 1 will match any of the following URLs:

• /Product/23
• /Product/7

Unfortunately, the route will also match the following URLs:

• /Product/blah
• /Product/apple

如果是第二個的話就會出錯，

routes.MapRoute( "Product", "Product/{productId}", new {controller="Product", action="Details"}, new {productId = @"/d+" } );

 

使用正則表達式
