TimeSpan 的 MultiBinding StringFormat [英] MultiBinding StringFormat of TimeSpan

问题描述

我这辈子都无法让它发挥作用.我需要从文本块中的一对时间跨度对象中显示 hh:mm ，但它不起作用.这是我目前所拥有的:

I cannot for the life of me get this to work. I need to display hh:mm from a pair of timespan objects in a textblock and it is just not working. This is what I have so far:

<TextBlock>
    <TextBlock.Text>
        <MultiBinding StringFormat="{}From {0:hh\\:mm} to {1:hh\\:mm}">
            <Binding Path="StartTime"/>
            <Binding Path="EndTime"/>
        </MultiBinding>
    </TextBlock.Text>
</TextBlock>

文本块显示为空白.我也尝试了以下相同的结果:

The text block shows up blank. I've also tried the following with the same results:

<TextBlock>
    <TextBlock.Text>
        <MultiBinding StringFormat="{}From {0} to {1}">
            <Binding Path="StartTime" StringFormat="hh\\:mm"/>
            <Binding Path="EndTime" StringFormat="hh\\:mm"/>
        </MultiBinding>
    </TextBlock.Text>
</TextBlock>

如果我将字符串格式设置为 hust "hh" 那么我只需要几个小时，所以我想我可以用 4 块来构建它，但这感觉不对.任何帮助表示赞赏.

If I have the string format as hust "hh" then I get just the hours, so I suppose I could build it out of 4 pieces but that just does not feel right. Any help is appreciated.

推荐答案

在格式字符串中使用 hh':'mm 似乎有效:

Using hh':'mm in the format string seems to work:

<TextBlock>
    <TextBlock.Text>
        <MultiBinding StringFormat="{}From {0:hh':'mm} to {1:hh':'mm}">
            <Binding Path="StartTime"/>
            <Binding Path="EndTime"/>
        </MultiBinding>
    </TextBlock.Text>
</TextBlock>

此外，这只适用于 .NET 4

Also, this only works in .NET 4
