CustomStart Engine中未呈现ViewStart.cshtml

Question

我已如下定义我的客户视图引擎，只是为了添加更多要搜索的位置。

public class CustomViewEngine : RazorViewEngine
    {
        private static string[] AdditionalViewLocations = new[]
        {
            "~/{1}/{0}.cshtml"
        };

        public CustomViewEngine() : base()
        {
            MasterLocationFormats = MasterLocationFormats.Union(AdditionalViewLocations).ToArray();
            PartialViewLocationFormats = PartialViewLocationFormats.Union(AdditionalViewLocations).ToArray();
            ViewLocationFormats = ViewLocationFormats.Union(AdditionalViewLocations).ToArray();

        }
    }

我现在面临的问题是，布局未应用于_ViewStart.cshtml页面中设置的任何视图。感谢您的帮助。
