用 + 和 - 符号格式化数字 [英] Format number with + and - sign

问题描述

我想对堆栈面板中的一些 WPF 文本块进行数据绑定和格式化.

I have some WPF textblocks in a stackpanel that I want to databind and format.

例如以下格式不带秒部分的日期 24 小时样式:

E.g. the following formats a date 24h style without the seconds part:

<TextBlock Text="{Binding MyCustomObject, StringFormat={}{0:HH:mm}}" />

现在，我想绑定一个整数并显示 + 和 - 符号(即 +6 或 -4).

Now, I would like to bind an integer and also display the + and - sign (i.e. +6 or -4).

<TextBlock Text="{Binding MyOtherCustomObject, StringFormat={}{0:+#}}" />

然而，这不起作用.这是可能的还是我必须为此编写一个完整的转换器?

This however, does not work. Is this possible or do I have to write a complete converter just for this?

编辑

Nikolays 的帖子让我找到了答案:

Nikolays post led me to the answer:

<TextBlock Text="{Binding MyOtherCustomObject, StringFormat={}{0:+#;-#;''}}" />

本质上，您提供了正数、负数的格式以及如何处理零的可选部分.在这种情况下，我说零应该显示为空字符串.

In essence you provide a format for positive numbers, negative numbers and an optional part what to do with zero. In this case I stated that a zero should be displayed as an empty string.

问候，

推荐答案

试试这个:

<TextBlock Text="{Binding MyOtherCustomObject, StringFormat={}{0:+#;-#;''}}" />
