将XAML中的标签文本设置为字符串常量 [英] Setting Label Text in XAML to string constant

问题描述

我有一个单一的字符串常量，我必须在几个不同的XAML布局中重复使用，所以我不想复制它，只想把它绑定到一个常量。

I have a single string constant that I have to re-use in several different XAML layouts, so instead of duplicating it, I'd like to just bind it to a constant.

我有一个类定义C＃中的字符串：

I have a class which defines the string in C#:

public static class StringConstants
{
     public static string MyString { get { return "SomeConstant"; } }
}

我希望能够通过XAML通过如下所示：

I'd like to be able to set the value through XAML via something like the following:

<Label Content="{Binding local:StringConstants.MyString}"/>

这是可以实现的吗？我已经搜索了例子，但是我只发现了一些在代码隐藏中有些修补的示例，我想知道是否有一个更简单的，仅限XAML的解决方案，如果我知道我只需要设置一次值一个字符串值永远不会改变。

Is this achievable? I've searched for examples, but I've only found samples that involve some tinkering in the code-behind and I'm wondering if there's a simpler, XAML-only solution if I know that I just need to set the value once based on a string value that will never change.

推荐答案

你绑定到一个静态成员，所以你应该使用 x：静态标记扩展：

You are binding to a static member so you should use x:Static Markup Extension:

<Label Content="{Binding Source={x:Static local:StringConstants.MyString}}"/>

根据@ HB的评论，没有必要使用Binding，因此使用起来更简单： p>

According to @H.B.'s comment it's not necessary to use Binding so it's simpler to use:

<Label Content="{x:Static local:StringConstants.MyString}"/>
