ASP.NET MVC 是否有任何 DateTime 路由约束？

ASP.NET MVC 是否包含任何嵌入到代码中的路由约束？如果是这样，我如何定义日期时间约束？

例如。网址:

http://mydomain.com/{versionDate}/{controller}/{action}
http://mydomain.com/2010-01-20/search/posts

干杯:)

does ASP.NET MVC contain any route contraints baked into the code? if so, how do i define a date-time constraint?

eg. url:

http://mydomain.com/{versionDate}/{controller}/{action}
http://mydomain.com/2010-01-20/search/posts

cheers :)

我最终制定了自己的路线限制。只花了几分钟。

using System;
using System.Web;
using System.Web.Routing;

namespace Whatever.Your.Funky.Cold.Medina.Namespace.Is
{
    public class DateTimeRouteConstraint : IRouteConstraint
    {
        #region IRouteConstraint Members

        public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values,
                          RouteDirection routeDirection)
        {
            DateTime dateTime;

            return DateTime.TryParse(values[parameterName] as string, out dateTime);
        }

        #endregion
    }
}

简单：P

I ended up making my own route constraint. only took a few mins.

using System;
using System.Web;
using System.Web.Routing;

namespace Whatever.Your.Funky.Cold.Medina.Namespace.Is
{
    public class DateTimeRouteConstraint : IRouteConstraint
    {
        #region IRouteConstraint Members

        public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values,
                          RouteDirection routeDirection)
        {
            DateTime dateTime;

            return DateTime.TryParse(values[parameterName] as string, out dateTime);
        }

        #endregion
    }
}

simple :P

您还可以对路线设置约束，类似这样。使用的正则表达式不是很健壮，因此您应该对其进行改进。

routes.MapRoute( 
    "Version", "
    {versionDate}/{controller}/{action}", 
    new {controller="Search", action="Posts"}, 
    new {versionDate= @"\d\d\d\d-\d\d-\d\d" } 
    );

信息来自此处。

You could also set up a constraint on the route, something like so. The regular expression used is not very robust, so you should refine it.

routes.MapRoute( 
    "Version", "
    {versionDate}/{controller}/{action}", 
    new {controller="Search", action="Posts"}, 
    new {versionDate= @"\d\d\d\d-\d\d-\d\d" } 
    );
