c# - 如何在 XAML 中将 FormatString 作为 ConverterParameter 传递

Question

我与转换器有绑定(bind)关系。我想将“#,,.0M”格式字符串作为转换器参数传递。

此 xaml 无效:

<local:SalesPerformanceControl FirstSalesVolume="{Binding Path=TodaySalesVolume, Converter={StaticResource ResourceKey=decimalToFormatedStringConverter}, ConverterParameter=#,,.0M}"/>

错误:

The type '' was not found.

如何正确传递这个字符串？

Answer 1

要么在要传递的字符串上使用单引号:

       <local:SalesPerformanceControl FirstSalesVolume="{Binding Path=TodaySalesVolume, Converter={StaticResource ResourceKey=decimalToFormatedStringConverter}, ConverterParameter='#,,.0M'}"/>

或者使用详细的语法来绑定(bind)，如下所示:

    <local:SalesPerformanceControl>
        <local:SalesPerformanceControl.FirstSalesVolume>
            <Binding Path="TodaySalesVolume" Converter="{StaticResource decimalToFormatedStringConverter}" ConverterParameter="#,,.0M" />
        </local:SalesPerformanceControl.FirstSalesVolume>
    </local:SalesPerformanceControl>
