我有一个xaml文件,我在其中导入转换器,但是当我尝试编译时 Visual Studio引发异常,并显示消息“无法解析程序集:'X'”。该转换器在同一个项目中,我从同一个项目中导入了一个行为,并且运行良好。我不知道我做错了什么,还是xamarin或Visual Studio的问题。
这是我的转换器
namespace YogaMobileApp.Converters
{
public class BoolNegation:IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if (targetType != typeof(bool))
throw new InvalidOperationException("The target must be a boolean");
return !(bool)value;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
if (targetType != typeof(bool))
throw new InvalidOperationException("The target must be a boolean");
return !(bool)value;
}
}
}
在我的Xaml中

When I try to compile vs throw an error "Failed to resolve assembly: 'YogaMobileApp' "
答案 0 :(得分:0)
此行似乎是错误的,可能导致此类错误,应该是:
<converters:BoolNegation x:Key="negation" />
