名称“StatusToStringConverter”在命名空间“clr-namespace：Editor”中不存在

Question

我正在尝试将数据绑定到WPF中的文本框。但它失败了。我在同一个应用程序中将Enum绑定到单选按钮，这很好用;但是当我尝试将Enum绑定到文本框时，它会失败。我做错了什么？

<Grid.Resources>
    <Style TargetType="{x:Type Button}" x:Key="formatTextStyle">
        <Setter Property="FontFamily" Value="Palatino Linotype"></Setter>
        <Setter Property="Width" Value="30"></Setter>
        <Setter Property="FontSize" Value ="14"></Setter>
        <Setter Property="CommandTarget" Value="{Binding ElementName=mainRTB}"></Setter>
    </Style>

    <Style TargetType="{x:Type MenuItem}" x:Key="formatImageStyle">
        <Setter Property="Width" Value="30"></Setter>
        <Setter Property="CommandTarget" Value="{Binding ElementName=mainRTB}"></Setter>
    </Style>
    <local:EnumToBooleanConverter x:Key="EnumToBooleanConverter" />
    <local:StatusToStringConverter x:Key="StatusToStringConverter" />
</Grid.Resources>

<RadioButton IsEnabled="False" Click="DisplayFormatChanged" Name="BinaryButton" Content="_Binary" IsChecked="{Binding Path=DisplayFormat, Mode=TwoWay, Converter={StaticResource EnumToBooleanConverter}, ConverterParameter={x:Static local:displayFormat.Binary}}" />
<RadioButton IsEnabled="False" Click="DisplayFormatChanged" Name="HexButton" Content="_Hex" IsChecked="{Binding Path=DisplayFormat, Mode=TwoWay, Converter={StaticResource EnumToBooleanConverter}, ConverterParameter={x:Static local:displayFormat.Hex}}" />

<TextBlock Name="Status"  IsEnabled="False" Text="{Binding Path=Status, Mode=TwoWay, Converter={StaticResource StatusToStringConverter}, ConverterParameter={x:Static local:Status.NotStarted}}"/>

背后的代码看起来像这样：

namespace Editor
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    { //rest of my code goes in here}

    [ValueConversion(typeof(displayFormat), typeof(Boolean))]
    public class EnumToBooleanConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

        {
            return value.Equals(parameter);
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return value.Equals(true) ? parameter : Binding.DoNothing;
        }
    }

    [ValueConversion(typeof(Status), typeof(String))]
    public class StatusToStringConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return value.ToString();
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return (Status)Enum.Parse(typeof(Status), value.ToString(), true);
        }
    }

}
