爱上MVC~在Views的多级文件夹~续~分部页的支持

回到目录

之前写的一篇文章，主要针对View视图，它可以放在N级目录下，不必须非要在views/controller/action这种关系了，而在程序运行过程中，发现分页视图对本功能并不支持，原因很简单，在RazorViewEngine有不同的属于来修饰这两个东西，对于View的查找，通过ViewLocationFormats来定义，而分部视图的查找通过PartialViewLocationFormats来定义，它们定义了视图的查询范围，如~/Views/LindAdmin/{1}/{0}.cshtml就可以表示在Views下面的LindAdmin下的目录。

对于分部页的多级目录结构

  /// <summary>
    /// 后台路由
    /// </summary>
    public class admin_routing : RazorViewEngine
    {
        public admin_routing()
        {
            //视图位置
            ViewLocationFormats = new[]
            {
              "~/Views/{1}/{0}.cshtml",
                "~/Views/LindAdmin/{1}/{0}.cshtml"//自定义汽车销售的试图
            };

            //分部视图位置
            PartialViewLocationFormats = new[]
            {
              "~/Views/{1}/{0}.cshtml",
                "~/Views/LindAdmin/{1}/{0}.cshtml"//自定义汽车销售的试图
            };
        }

        public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache)
        {
            return base.FindView(controllerContext, viewName, masterName, useCache);
        }

        public override ViewEngineResult FindPartialView(ControllerContext controllerContext, string partialViewName, bool useCache)
        {
            return base.FindPartialView(controllerContext, partialViewName, useCache);
        }
    }

我们通过上面的代码看到了FindView和FindPartialView两个方法，它们就是在渲染视图时的查找方法，即你的action要去渲染哪个视图，我们可以把自己的逻辑重写在这两个

方法里！

看一下大家的通用后台项目，将后台的一些View都放到了LindAdmin里，而这也是为了打包考虑的，以后哪个具体的项目希望用后台，直接NUGET安装即可，边页面都不用做了，哈哈！
