WPF 绑定 StringFormat 短日期字符串 [英] WPF Binding StringFormat Short Date String

问题描述

我想在 WPF 中使用短日期命名字符串格式.

I would like to use Short Date named string format in WPF.

我尝试了类似的东西:

<TextBlock Text="{Binding Date, StringFormat='Short Date'}" />

如何做到这一点?

推荐答案

试试这个:

<TextBlock Text="{Binding PropertyPath, StringFormat=d}" />

这是文化敏感的，需要 .NET 3.5 SP1 或更高版本.

which is culture sensitive and requires .NET 3.5 SP1 or above.

注意:这是区分大小写的."d" 是 短日期格式说明符，而 "D"是长日期格式说明符.

NOTE: This is case sensitive. "d" is the short date format specifier while "D" is the long date format specifier.

但是，这有一个问题 - 它总是以美国格式输出日期，除非您自己将文化设置为正确的值.

However, there is one gotcha with this - it always outputs the date in US format unless you set the culture to the correct value yourself.

如果不设置此属性，绑定引擎将使用绑定目标对象的语言属性.在 XAML 中，这默认为en-US"或从页面的根元素(或任何元素)继承值(如果已显式设置).

If you do not set this property, the binding engine uses the Language property of the binding target object. In XAML this defaults to "en-US" or inherits the value from the root element (or any element) of the page, if one has been explicitly set.

执行此操作的一种方法是在后面的代码中(假设您已将线程的区域性设置为正确的值):

One way to do this is in the code behind (assuming you've set the culture of the thread to the correct value):

this.Language = XmlLanguage.GetLanguage(Thread.CurrentThread.CurrentCulture.Name);

另一种方法是在绑定中设置转换器文化:

The other way is to set the converter culture in the binding:

<TextBlock Text="{Binding PropertyPath, StringFormat=d, ConverterCulture=en-GB}" />

虽然这不允许您本地化输出.

Though this doesn't allow you to localise the output.
