XML命名空间'clr-namespace:XXX'中不存在标记'XXX'

标签: c# wpf xaml ivalueconverter

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:

    public class BoolToValueConverter<T> : IValueConverter
    {
        public T FalseValue { get; set; }
        public T TrueValue { get; set; }

        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            if (value == null)
                return FalseValue;
            else
                return (bool)value ? TrueValue : FalseValue;
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return value != null ? value.Equals(TrueValue) : false;
        }
    }
}

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。

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.ObjectTrueValue的{​​{1}}属性,FalseValueConvert无论如何工作ConvertBack

System.Object
