标记'XXX'不存在于XML命名空间'clr-namespace：XXX'

我有这个典型的标记'XXX'不存在于XML命名空间'clr-namespace：XXX'问题，但我真的找不到我犯错的地方。标记'XXX'不存在于XML命名空间'clr-namespace：XXX'

以下是错误消息：

d：\ CUI \项目\ FijiLauncherTester \ FijiLauncherTester \ Window1.xaml（9,14）：错误MC3074：标记 'BoolToValueConverter' 中不存在XML 命名空间'clr-namespace：FijiLauncherTester'。第9行14位完成建设项目“FijiLauncherTester.csproj” - 失败

在Xmal位的是其中搞砸了，但我在XAML后面的C＃代码中定义它。

C＃？我想念什么？我应该如何改变它？谢谢。

问题是你的BoolToValueConverter类是泛型类。 WPF正在寻找非通用BoolToValueConverter，而不是BoolToValueConverter<T>。

由于这是一个转换器，你可以删除仿制药，而只使用一个System.Object属性为TrueValue和FalseValue，为Convert和System.ObjectConvertBack工作反正：

public class BoolToValueConverter : IValueConverter 
{ 
    // Note that you're never setting this! 
    public object FalseValue { get; set; } 
    public object 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; 
    } 
}

你的意思是将其移动空间外面FijiLauncherTester {}？不，它不像我尝试那样工作。 –

@NickXTsui不，我的意思是你需要摆脱类上的'';）XAML不喜欢泛型，不理解寻找泛型类。 –

你可以在这里粘贴修改后的C＃代码吗？我不是C＃专家，如果我理解正确，看起来不会有太大变化吗？谢谢。 –
