MVC与Webform混合开发

在实际项目中我们会想到用Asp.net MVC 做前台，WebForm做后台。既有性能又有开发效率。在MVC中实现两者混合开发也很容易。

我们这里介绍两种方：

第一种：设置路由忽略对WebForm的.aspx文件的控制访问

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

            routes.MapRoute(
                "Account",
                "Account/{action}",
                new { controller = "LoinAccount", action = "Index" }

           );

            routes.MapRoute(
                "ads",
                "Ads/{action}/{id}/{num}",
                new { controller = "Ads", action = "ListAd" },
                new { num = @"\d+" }
            );

            routes.MapRoute(
                "News",
                "News/Get_{newsId}/{year}/{month}/{day}.htm",
                new { controller = "News", action = "Index" }
            );

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

        }

第二种：自已实现一个RouteHandler

/// <summary>
    /// 对WebForms文件夹的路径处理
    /// </summary>
    public class WebFormsRouteHandler : IRouteHandler
    {
        private string _pageName = string.Empty;


        public IHttpHandler GetHttpHandler(RequestContext requestContext)
        {
            // 从URL中获取page参数
            _pageName = requestContext.RouteData.GetRequiredString("page");
            IHttpHandler hander = BuildManager.CreateInstanceFromVirtualPath("/WebForms/" + this._pageName + ".aspx", typeof(System.Web.UI.Page)) as IHttpHandler;
            return hander;
        }
    }

    /// <summary>
    /// 对WebForms里的子文件夹路径处理
    /// </summary>
    public class WebFormsFolderRouteHandler : IRouteHandler
    {
        private string _folderName = string.Empty;
        private string _pageName = string.Empty;

        public IHttpHandler GetHttpHandler(RequestContext requestContext)
        {
            // 从URL中获取folder参数
            _folderName = requestContext.RouteData.GetRequiredString("folder");
            // 从URL中获取page参数
            _pageName = requestContext.RouteData.GetRequiredString("page");

            IHttpHandler hander;
            // 创建实例
            // 根据folder 和 page 参数拼接成类似/WebForms/folder/page.aspx地址来访问WebForms页面
            hander = BuildManager.CreateInstanceFromVirtualPath("/WebForms/" + this._folderName + "/" + this._pageName + ".aspx", typeof(System.Web.UI.Page)) as IHttpHandler;
            return hander;

        }
    }

接下来新建WebForms文件夹，在其文件夹或子文件夹里添加aspx页面

最后再设置路由

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

            // 添加一个用WebFormsRouteHandler进行处理的路由
            // 其中URL中{page}所占的部分会被在WebFormsRouteHandler中当做参数使用
            routes.Add(new Route("web/{page}", new WebFormsRouteHandler()));
            // 其中URL中{folder}和{page}所占的部分会被在WebFormsRouteHandler中当做参数使用
            routes.Add(new Route("web/{folder}/{page}", new WebFormsFolderRouteHandler()));

            routes.MapRoute(
                "Account",
                "Account/{action}",
                new { controller = "LoinAccount", action = "Index" }

           );

            routes.MapRoute(
                "ads",
                "Ads/{action}/{id}/{num}",
                new { controller = "Ads", action = "ListAd" },
                new { num = @"\d+" }
            );

            routes.MapRoute(
                "News",
                "News/Get_{newsId}/{year}/{month}/{day}.htm",
                new { controller = "News", action = "Index" }
            );

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

        }

这样就行了，如果觉得URL不够漂亮还可以修改路由里的路径让URL好看点。
