玻璃映射器异常:不能将值PermanentRedirect转换为枚举类型

Question

我在我的项目解决方案中得到玻璃映射器异常，如下

stack trace:

我的渲染类如下所示，

 public class Redirection : RenderingModel
    {
        [SitecoreField("Destination")]
        public virtual Glass.Mapper.Sc.Fields.Link Destination { get; set; }
        [SitecoreField("Type")]
        public virtual StatusCodes Type { get; set; }
    }
    public enum StatusCodes
    {
        Permanent = 301,
        Temporary = 302
    }

我的控制器方法是这样的，

public ActionResult Redirect()
        {
            var context = new SitecoreContext(IdpTemplates.CurrentContext);
            var redirection = context.GetCurrentItem<Redirection>();
            return new RedirectResult(redirection.Destination.Url, Convert.ToInt32(redirection.Type) == 301);
        }

在上面的方法中，我在var重定向= context.GetCurrentItem()中得到异常;线。

Answer 1

您的字段值包含'PermanentRedirect'，但您的enum没有该值。它有:"永久"one_answers"临时"。

名称必须精确匹配(区分大小写)。也许你在某个时间点改变了它?或者你有一个错误的默认值?
