整数类型的WPF资源 [英] WPF resource of integer type

问题描述

我是WPF的新手，我想自己学习。我遇到了资源，我想问一个简单的（可能是一个愚蠢的）问题..我创建了这样的资源

 <   Window.Resources  >  
 <   sys：String     x：键  =  strHelloWorld >  Hello，world！<   / sys：String  >  
 <   sys：Int16     x：Key   =   intKey >  34 <   / sys：Int16  >  
 <   / Window.Resources  >  

我正在尝试使用这样的键值显示

 <   StackPanel    保证金  =  10 >  
 <   TextBlock    文本  =  {StaticResource strHelloWorld}    FontSize   =  56    /  >  
 <   TextBlock  > 只是另一个 <   TextBlock    文本  =  {StaticResource strHelloWorld}    /  > 示例，但有资源！<   / TextBlock  >  
 < span class =code-keyword><   / Stack面板 >  
 

我当时能够显示字符串类型属性，但如何在文本块中显示int资源或是否可能???



我能够做到这个使用标签...像这样



<前lang =xml> < 标签 内容 = {StaticResource intKey} > < /标签 >

提前谢谢

解决方案

自 TextBlock以来，你不能直接这样做.Text 想要一个字符串，而不是 Int16 。

标签作品b因为 Content 属性的类型是 object 所以它是 ContentPresenter 如果需要，将自动调用 .ToString（）。

TextBlock中没有任何内容可以进行转换。

你可以使用绑定的StringFormat属性使其工作：

 <   TextBlock    文本  =  {StaticResource strHelloWorld，StringFormat = {0}}    FontSize   =  56 < span class =code-attribute>   /  >  

Hi,

i am new to WPF and i trying to study by myself. I came across resource and i want to ask a simple (may be a dumb ) question.. I have created a resource like this

<Window.Resources>
        <sys:String x:Key="strHelloWorld">Hello, world!</sys:String>
        <sys:Int16 x:Key="intKey">34</sys:Int16>
    </Window.Resources>

I am trying to display using the key value like this

<StackPanel Margin="10">
     <TextBlock Text="{StaticResource strHelloWorld}" FontSize="56" />
     <TextBlock>Just another "<TextBlock Text="{StaticResource strHelloWorld}" />"  example, but with resources!</TextBlock>
 </StackPanel>

I was able to display the string type property without fail, but how can i display the int resource in a text block or is it possible ???

I was able to do this using label... like this

<Label Content="{StaticResource intKey}"></Label>

Thanks in advance

解决方案

You can't do it directly since the TextBlock.Text wants a string, not an Int16.
The Label works because the type of the Content property is object so it's ContentPresenter will automatically call .ToString() if necessary.
There's nothing in the TextBlock to do the conversion.
You can use the StringFormat property of the binding to make it work:

<TextBlock Text="{StaticResource strHelloWorld, StringFormat={0}}" FontSize="56" />
