如何使用StringFormat强制显示'+'符号

Is there a way to force showing the + sign in front of positive numbers when using StringFormat?

使用StringFormat时，是否有办法强制在正数前面显示+号?

For example:

例如:

<TextBlock Text="{Binding Path=PercentAgainstBudget, 
                          StringFormat={}{0:0.00}%}" />

If PercentAgainstBudget is negative I see the - sign. But if its positive, it does not. Since this number is an offset, I'd like to force showing +/-. I could make a ValueConverter but I'm wondering if there's a way to do it through the StringFormat property.

如果百分之一的预算是负数，我看到了。但如果它是正数，它就不是。由于这个数字是一个偏移量，我想强制显示+/-。我可以做一个ValueConverter，但是我想知道是否可以通过StringFormat属性来实现它。

The format string can be made of two parts separated by a semicolon. First part is the format of positive numbers, second of negative. You'll want this: +0.0%;-0.0%

格式字符串可以由分号分隔的两部分组成。第一部分是正数的格式，第二部分是负数的格式。你需要的是这样的:+ 0.0%;-0.0%

PS C:\Users\jachymko> '{0:+0.0%;-0.0%}' -f 2.45
+245,0%
PS C:\Users\jachymko> '{0:+0.0%;-0.0%}' -f -2.45
-245,0%
