如何使用< x：array> xaml语言中字符串的标记扩展 [英] how to use an <x:array> markup extension for strings in xaml language

问题描述

我如何使用< x：array xmlns：x =＃unknown>对于xaml 4.0中的字符串，用于在wpf应用程序中实现动态资源，其中两个组合框具有3个字符串类型的元素

解决方案

你的意思是静态资源吗？这将在XAML中声明（虽然这在可维护性和可扩展性方面很糟糕......）



无论如何，如果你正在寻找静态资源，那么，

  //   1.在您的Window标记声明使用.NET System命名空间 
 
< window x： class  =   WpfTutorialSamples.WPF_Application.ExtendedResourceSample xmlns：x =  ＃unknown >  
 xmlns =   http://schemas.microsoft.com/winfx/2010/xaml/presentation 
 xmlns：x =   http://schemas.microsoft.com/winfx/2010/xaml 
 xmlns：s =   clr-namespace：System; assembly = mscorlib 
 Title =   StaticResourceComboboxSample 
高度=   400 
 Width =   300 >  
 
  //   2.现在，名称空间别名's'对应于System名称空间在mscorlib.dll中，它具有定义的标准类型。 
 
  //   3.创建静态资源，它具有一个密钥属性，稍后将使用该属性将该资源用于/关联到控件，例如在你的情况下组合框。 
 
< x：array x：key =   CBXDropdownItems type =   s：String >  
< s： string  xmlns：s =  ＃unknown> < /   s ：string  >  
< s： string  xmlns：s = < span class =code-string> ＃unknown> B < /   s：string  >  
< s： string  xmlns：s =  ＃unknown> C < /   s：string  >  
 < /   x：array  >  
 
  //   4.现在，我们所要做的就是将此资源（密钥）与控件的数据源（ItemsSource属性）相关联。 
 
< combobox itemssource =   {StaticResource CBXDropdownItems} /> < /   window  >  

how can i use <x:array xmlns:x="#unknown"> for strings in xaml 4.0 for implementing dynamic resources in wpf application in which two combobox having 3 elements of string type

解决方案

Do you mean a static resource? This would be declared in XAML (though this is bad from maintainability and extensibility aspects...)

Anyways, if you are looking for static resource then,

// 1. In your Window tag declare usage of .NET System namespace

  <window x:class="WpfTutorialSamples.WPF_Application.ExtendedResourceSample" xmlns:x="#unknown">
          xmlns="http://schemas.microsoft.com/winfx/2010/xaml/presentation"
          xmlns:x="http://schemas.microsoft.com/winfx/2010/xaml"
          xmlns:s="clr-namespace:System;assembly=mscorlib"
          Title="StaticResourceComboboxSample" 
          Height="400"
          Width="300">

// 2. Now, namespace alias 's' corresponds to System namespace in mscorlib.dll and this has the standard types defined.

// 3. Create a static resource, it has a key property which will be used later to use/associate this resource to a control e.g. combo-box in your case.

  <x:array x:key="CBXDropdownItems" type="s:String">
    <s:string xmlns:s="#unknown">A</s:string>
    <s:string xmlns:s="#unknown">B</s:string>
    <s:string xmlns:s="#unknown">C</s:string>
  </x:array>

// 4. Now all we have to do is associate this resource (key) to the control's data source (ItemsSource property).

  <combobox itemssource="{StaticResource CBXDropdownItems}" /></window>
