xaml资源键类型

定义方式	优点	缺点	适用场景
普通字符串键	简单直观，易于使用	命名冲突风险，无法跨程序集共享	小型项目，局部资源
类型键	自动应用，无需显式引用	灵活性较低	全局样式，基础样式复用
静态资源键	强类型支持，可维护性高	定义稍复杂	大型项目，组件化开发
`ComponentResourceKey`	跨程序集支持，语义化标识	定义和使用复杂	组件库开发，主题或样式库
动态资源键	动态绑定，灵活性高	性能开销	主题切换，多语言支持

//普通字符串键
<Style x:Key="MyButtonStyle" TargetType="Button" />

//类型键（隐式样式）
<Style TargetType="Button">
    <Setter Property="Background" Value="LightBlue" />
</Style>

//静态资源键
public static class ResourceKeys
{
    public static readonly string CloseButtonStyle = "CloseButtonStyle";
}

<Style x:Key="{x:Static local:ResourceKeys.CloseButtonStyle}" TargetType="Button" />

//组件资源键ComponentResourceKey

    public partial class DataTemplateKeys
    {
        public static ComponentResourceKey ItemClose => new ComponentResourceKey(typeof(DataTemplateKeys), "S.DataTemplate.Item.Close");
    }
<DataTemplate x:Key="{ComponentResourceKey ResourceId=S.DataTemplate.Item.Close, TypeInTargetAssembly={x:Type local:DataTemplateKeys}}">

//静态资源键与组件资源键结合

public static class ResourceKeys
{
    public static readonly ComponentResourceKey CloseButtonStyleKey = new ComponentResourceKey(typeof(ResourceKeys), "CloseButtonStyle");
}

<Style x:Key="{x:Static local:ResourceKeys.CloseButtonStyleKey}" TargetType="Button" />

//动态资源键
<Button Style="{DynamicResource MyButtonStyle}" />
