Message in Chinese (Simplified) (中文(简体))
无法确定集合类型“<var>Type Name</var>”的项类型，因为它有多个 Add 方法或 ICollection<t> 实现。若要使此集合类型可在 XAML 中使用，请添加一个公共的 Add(object) 方法，并实现 System.Collections.IList 或单个 System.Collections.Generic.ICollection<t>。</t></t>
Unlocalized message
Cannot determine the item type of collection type '<var>Type Name</var>' because it has more than one Add method or ICollection<t> implementation. To make this collection type usable in XAML, add a public Add(object) method, implement System.Collections.IList or a single System.Collections.Generic.ICollection<t>.</t></t>
