我尝试实现IValueConverter类并将其映射为xaml文件中的资源。在某些原因,我总是得到错误“名称TypeConverter在命名空间clr-namespace中不存在:MyApp”
但是我找不到那里的问题,我的转换器类已经正确设置了命名空间等等。
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>
我的转换器类
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;
}
}
}
答案 0 :(得分:0)
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
修复此问题后,编译器(和)设计器不再提供命名空间错误。
