Asp.net MVC学习笔记3----Route的限制

假如在Gloable.ascx文件中定义了如下的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(); } }}

 

如果输入的参数不能转化整形的话，就会出错，

 

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

如果是第二个的话就会出错，

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

 

使用正则表达式
