Glass.Mapper.MapperException: 未能创建类型 - 没有为此对象定义无参数构造函数
Glass.Mapper.MapperException: Failed to create type - No parameterless constructor defined for this object
继之前的 post 之后，我正在 Sitecore 中实施 this YouTube Video Picker - 这涉及创建自定义字段类型 (YouTubeVideoField)。控件本身没有问题但是当试图在页面上获取视频时 (@Html.Sitecore().Field("YouTube Video")) 我收到以下错误.有什么想法吗？

您可能需要实施自定义数据处理程序。如果您想使用提供的自定义字段，请参阅这些示例：
