内置的 WPF I 值转换器

好的，发现在 系统，视窗，控制名称空间中已经有一个 BooleToVisibilityConverter，这是一个很好的惊喜(在写了几次之后)。

也许还有更多这样隐藏的节省时间的方法。

有人有吗？

Before 3.5 SP1, an IValueConverter was required for string formatting. Now, you can use the StringFormat property on Binding to do this.

From the MSDN page:

<DataTemplate>
<TextBlock>
<TextBlock.Text>
<MultiBinding  StringFormat="{}{0} -- Now only {1:C}!">
<Binding Path="Description"/>
<Binding Path="Price"/>
</MultiBinding>
</TextBlock.Text>
</TextBlock>
</DataTemplate>

I did a quick trawl using the Object Browser and this is what I have.

Derived from IValueConverter:

System.Windows.Controls.AlternationConverter
System.Windows.Controls.BooleanToVisibilityConverter
System.Windows.Documents.ZoomPercentageConverter
System.Windows.Navigation.JournalEntryListConverter

Xceed.Wpf.DataGrid.Converters.CurrencyConverter
Xceed.Wpf.DataGrid.Converters.DateTimeToStringConverter
Xceed.Wpf.DataGrid.Converters.GreaterThanZeroConverter
Xceed.Wpf.DataGrid.Converters.IndexToOddConverter
Xceed.Wpf.DataGrid.Converters.IntAdditionConverter
Xceed.Wpf.DataGrid.Converters.InverseBooleanConverter
Xceed.Wpf.DataGrid.Converters.LevelToOpacityConverter
Xceed.Wpf.DataGrid.Converters.MultimodalResultConverter
Xceed.Wpf.DataGrid.Converters.NegativeDoubleConverter
Xceed.Wpf.DataGrid.Converters.NullToBooleanConverter
Xceed.Wpf.DataGrid.Converters.SourceDataConverter
Xceed.Wpf.DataGrid.Converters.StringFormatConverter
Xceed.Wpf.DataGrid.Converters.ThicknessConverter
Xceed.Wpf.DataGrid.Converters.TypeToBooleanConverter
Xceed.Wpf.DataGrid.Converters.TypeToVisibilityConverter
Xceed.Wpf.DataGrid.Converters.ValueToMaskedTextConverter

Derived from IMultiValueConverter:

System.Windows.Controls.BorderGapMaskConverter
System.Windows.Navigation.JournalEntryUnifiedViewConverter
System.Windows.Controls.MenuScrollingVisibilityConverter

Microsoft.Windows.Themes.ProgressBarBrushConverter
Microsoft.Windows.Themes.ProgressBarHighlightConverter

Note the Xceed ones (no connection) are available free with their DataGrid. As well as those there's some clever stuff around like the debugging converter. I've also used the last IValueConverter and I'm sure there's some further lambda function goodness to be found, too.
