WPF 读ResouceDictionary 报错的问题

场景：在WPF中读取ResouceDictionary中自定义的对象

例子：

1<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
2    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
3    xmlns:list="clr-namespace:Disappearwind.BlogSolution.BlogTools">

错误描述："Missing XmlNamespace, Assembly, or ClrNamespace in Mapping instruction. Line '3' Position '5'."

原因：自定义对象的引用有问题，除了要引用对象的类型信息外还需要引用程序集信息：

1<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
2    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
3    xmlns:list="clr-namespace:Disappearwind.BlogSolution.BlogTools;assembly=Disappearwind.BlogSolution.BlogTools">

 

注意assembly=后面的就是程序集的信息。
