WPF中后端bool是否可见字段转换为前端Visibility

1.编写转换类Bool2VisibilityConverter，继承自IValueConverter（using System.Windows.Data;）

  public class Bool2VisibilityConverter : IValueConverter
  {
      public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
      {
          if (value != null && bool.TryParse(value.ToString(), out bool result) && result)
              return Visibility.Visible;

          return Visibility.Collapsed;
      }

      public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
      {
          throw new NotImplementedException();
      }
  }

 

2.前端页面在UserControl.Resources节点中进行转换器的引用定义

    <UserControl.Resources>
        <converter:Bool2VisibilityConverter x:Key="Bool2VisibilityConverter"/>
    </UserControl.Resources>

 

3.根据bool字段绑定判断是否显示

            <Grid VerticalAlignment="Top" Margin="15,0" 
                  Visibility="{Binding PageModel.IsShowDetail,
                  Converter={StaticResource Bool2VisibilityConverter}}">
            </Grid>
