XAML找不到轉換器類

我顯示彈出下面的代碼：XAML找不到轉換器類

<Popup PlacementTarget="{Binding ElementName=categoryTagEditorControl}" 
     Placement="Bottom"> 
    <Popup.IsOpen> 
     <MultiBinding Mode="OneWay" Converter="{StaticResource BooleanOrConverter}"> 
      <Binding Mode="OneWay" ElementName="categoryTagEditorControl" Path="IsMouseOver"/> 
      <Binding RelativeSource="{RelativeSource Self}" Path="IsMouseOver" /> 
     </MultiBinding> 
    </Popup.IsOpen> 
    <StackPanel> 
     <TextBox Text="Some Text.."/> 
     <DatePicker/> 
    </StackPanel> 
</Popup>

這裏的BooleanOrConverter的代碼：

public class BooleanOrConverter : IMultiValueConverter 
{ 
    public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
    { 
     foreach (object booleanValue in values) 
     { 
      if (booleanValue is bool == false) 
      { 
       throw new ApplicationException("BooleanOrConverter only accepts boolean as datatype"); 
      } 
      if ((bool)booleanValue == true) 
      { 
       return true; 
      } 
     } 
     return false; 
    } 
    public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture) 
    { 
     throw new NotSupportedException(); 
    } 
}

其放入PopupTest.InfoPanels。 Windows命名空間

當我運行這個，我得到以下異常：

Cannot find resource named 'BooleanOrConverter'. Resource names are case sensitive.

我該怎麼改變才能工作？

嘗試增加你的轉換器類的對象到相關資源字典，然後使用'DynamicResource ' – nakiya 2012-04-20 02:51:33

這聽起來像你的Multibinding不知道在哪裏尋找轉換器。您是否將轉換器定義爲staticresource？您可以在控件資源中或在附帶的ResourceDictionary中指定轉換器。添加對轉換器名稱空間的引用，然後爲其定義ResourceKey。喜歡的東西：

<UserControl 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:converters="clr-namespace:MyConverters"> 

    <UserControl.Resources> 
      <converters:BooleanOrConverter x:Key="BoolOrConverter"/> 
    </UserControl.Resources> 

    ... // use converter as you were before 

</UserControl>

使用<轉換器：BooleanOrConverter X：鍵= 「BooleanOrConverter」/>。改變鑰匙只是爲了避免混淆。 – 2012-04-20 06:30:13
