回答by Martin Harris
There is a string format property available when you are declaring the binding:
声明绑定时，有一个字符串格式属性可用：
<TextBox Text="{Binding Path=DateTimeValue, StringFormat=dd-MM-yyyy}" />
(You need to be on .NET 3.5 SP1 for this property to exist)
（您需要在 .NET 3.5 SP1 上才能存在此属性）

If you want to use a common format stringbetween bindings, you could declare the binding like this:
如果要在绑定之间使用通用格式字符串，可以像这样声明绑定：
<Textbox Text={Binding Path=DateTimeValue, StringFormat={x:Static local:Constants.DateTimeUiFormat}} />
With your constants class like this:
使用这样的常量类：
public static class Constants
{
public const string DateTimeUiFormat = "dd/MM/yyyy";
//etc...
}

May be helpful to someone:
可能对某人有帮助：
<TextBlock Text="{Binding Source={x:Static sys:DateTime.Now},
StringFormat='{}{0: Today is dddd, MMMM dd, yyyy, hh:mm:ss}'}"/>
or 24h and 2digits month and year format:
或 24h 和 2digits 月份和年份格式：
<TextBlock Text="{Binding Source={x:Static sys:DateTime.Now},
StringFormat='{}{0: Today is dddd, MM.dd.yy, HH:mm:ss}'}"/>
