我有这个典型的标签'XXX'在XML命名空间'clr-namespace:XXX'问题中不存在,但我真的找不到我做错的地方。
以下是错误消息:
d:\ CUI \项目\ FijiLauncherTester \ FijiLauncherTester \ Window1.xaml(9,14): 错误MC3074:XML中不存在标记'BoolToValueConverter' namespace'clr-namespace:FijiLauncherTester'。第9行位置14.完成 建设项目“FijiLauncherTester.csproj” - 失败
xmal中的local:BoolToValueConverter
是混乱的地方,但我已经在xaml后面的C#代码中定义了它。
XAML:

我想知道这里发生了什么?我想念什么?我该怎么改变它?感谢。
答案 0 :(得分:3)
问题是你的BoolToValueConverter
类是泛型类。 WPF正在寻找非通用的BoolToValueConverter
,而不是BoolToValueConverter<T>
。
由于这是一个转换器,您可以删除泛型,只需使用System.Object
和TrueValue
的{{1}}属性,FalseValue
和Convert
无论如何工作ConvertBack
:
System.Object
