用于多门户结构的ASP.NET MVC5自定义RazorViewEngine

public class CustomRazorViewEngine : RazorViewEngine
{
    public CustomRazorViewEngine()
    {
        // 添加自定义的视图查找规则
        ViewLocationFormats = new[]
        {
            "~/Views/{1}/{0}.cshtml",
            "~/Views/Shared/{0}.cshtml",
            "~/Views/Portals/{1}/{0}.cshtml" // 多门户结构中的视图路径
        };
    }

    protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)
    {
        // 自定义视图创建逻辑
        // 可以在此处添加一些额外的逻辑，如权限验证等
        return base.CreateView(controllerContext, viewPath, masterPath);
    }

    protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)
    {
        // 自定义部分视图创建逻辑
        return base.CreatePartialView(controllerContext, partialPath);
    }
}

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        // 注册自定义的RazorViewEngine
        ViewEngines.Engines.Clear();
        ViewEngines.Engines.Add(new CustomRazorViewEngine());

        // 其他应用程序启动逻辑
        // ...
    }
