Question

以下代码抛出“未将对象引用设置为对象的实例”。错误，我无法弄清楚为什么。当我调试时，我的模型有我期待的数据。看起来很简单，不确定我做错了什么。

@using(BeginRenderLink(Model, x => x.Page, isEditable: true))
{
    @RenderImage(Model, x => x.IconImage, isEditable: true);
    @Editable(Model, x => x.Headline);
}

更新：如果我从BeginRenderLink块中取出以下两行，它们将按预期工作。希望这对你们其中一个人有意义......

@RenderImage(Model, x => x.IconImage, isEditable: true);
@Editable(Model, x => x.Headline);
