我嘗試實現IValueConverter類並將其映射爲xaml文件中的資源。在某種原因,即時獲得永諾錯誤「的名稱類型轉換器不會在命名CLR的命名空間中:MyApp的」IValueConverter資源,命名空間問題
但我找不到什麼問題出現,我的轉換器類已命名空間設定正確等。
我的XML文件
<phone:PhoneApplicationPage
x:Class="MyApp.Page"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:MyApp"
FontFamily="{StaticResource PhoneFontFamilyNormal}"
FontSize="{StaticResource PhoneFontSizeNormal}"
Foreground="{StaticResource PhoneForegroundBrush}"
SupportedOrientations="Portrait" Orientation="Portrait"
mc:Ignorable="d"
shell:SystemTray.IsVisible="True">
...
<ListBox ItemsSource="{Binding items}" ScrollViewer.VerticalScrollBarVisibility="Disabled">
<ListBox.Resources>
<local:TypeConverter x:Name="TypeConverter"/>
</ListBox.Resources>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding type, Converter={StaticResource TypeConverter}}" Margin="0,0,12,0" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
我的轉換器類
namespace MyApp
{
public class TypeConverter: IValueConverter
{
public object Convert(object value, Type targetType, object parameter, String culture)
{
return "-";
}
public object ConvertBack(object value, Type targetType, object parameter, String culture)
{
return null;
}
}
}
錯誤出現在設計器或編譯時? –
