我的 .xaml 页面代码:
<phone:PhoneApplicationPage
x:Class="MVVM1Test.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:converter="clr-namespace:MVVM1Test.Resources.Converters"
mc:Ignorable="d"
SupportedOrientations="Portrait" Orientation="Portrait"
shell:SystemTray.IsVisible="True">
<phone:PhoneApplicationPage.Resources>
<converter:NotConverter x:Name="not"></converter:NotConverter>
</phone:PhoneApplicationPage.Resources>
<!--LayoutRoot is the root grid where all page content is placed-->
<Grid x:Name="LayoutRoot" Background="Gray">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
</Grid>
</phone:PhoneApplicationPage>
notconverter.cs
namespace MVVM1Test.Resources.Converters
{
public class NotConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return !(bool)value;
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return !(bool)value;
}
}
}
它显示错误
“名称 NotConverter 不存在于命名空间 clr-namespace:MVVM1Test.Resources.Converters”
但我也将转换器类添加到解决方案中。
