標記'XXX'不存在於XML命名空間'clr-namespace：XXX'

我有這個典型的標記'XXX'不存在於XML命名空間'clr-namespace：XXX'問題，但我真的找不到我犯錯的地方。標記'XXX'不存在於XML命名空間'clr-namespace：XXX'

以下是錯誤消息：

d：\ CUI \項目\ FijiLauncherTester \ FijiLauncherTester \ Window1.xaml（9,14）：錯誤MC3074：標記 'BoolToValueConverter' 中不存在XML 命名空間'clr-namespace：FijiLauncherTester'。第9行14位完成建設項目「FijiLauncherTester.csproj」 - 失敗

在Xmal位的是其中搞砸了，但我在XAML後面的C＃代碼中定義它。

我想知道是怎麼回事

    </Grid> 
</Window>

C＃？我想念什麼？我應該如何改變它？謝謝。

問題是你的BoolToValueConverter類是泛型類。 WPF正在尋找非通用BoolToValueConverter，而不是BoolToValueConverter<T>。

由於這是一個轉換器，你可以刪除仿製藥，而只使用一個System.Object屬性爲TrueValue和FalseValue，爲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; 
    } 
}

你的意思是將其移動空間外面FijiLauncherTester {}？不，它不像我嘗試那樣工作。 –

@NickXTsui不，我的意思是你需要擺脫類上的'';）XAML不喜歡泛型，不理解尋找泛型類。 –

你可以在這裏粘貼修改後的C＃代碼嗎？我不是C＃專家，如果我理解正確，看起來不會有太大變化嗎？謝謝。 –
