WPF中样式和模板区别


    <div style="color: black; text-align: left; margin-bottom: 10px;">
      <div style="color: black; text-align: left; margin-bottom: 10px;">
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">WPF（Windows Presentation Foundation）中的样式和模板都是用于控件外观的重要机制，但它们的目的和<span style="color: black;">运用</span>方式略有<span style="color: black;">区别</span>。</p>
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1. 样式</p>
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">样式是一种<span style="color: black;">能够</span>重复<span style="color: black;">运用</span>的视觉元素，用于定义控件的外观和<span style="color: black;">行径</span>。一旦定义一个样式，<span style="color: black;">能够</span>在应用程序中的多个控件中重复<span style="color: black;">运用</span>它。样式<span style="color: black;">能够</span><span style="color: black;">包括</span>多种视觉元素，如布局属性、事件触发程序、转换器和动画等。要<span style="color: black;">运用</span>样式，<span style="color: black;">能够</span>在XAML文件中定义"Style"元素，并在控件上设置"Style"属性。以下是一个简单的样式示例：</p><span style="color: black;">```xml</span><span style="color: black;"><span style="color: black;">&lt;<span style="color: black;">Window.Resources</span>&gt;</span></span><span style="color: black;"> <span style="color: black;">&lt;<span style="color: black;">Style</span> <span style="color: black;">x:Key</span>=<span style="color: black;">"RedButtonStyle"</span> <span style="color: black;">TargetType</span>=<span style="color: black;">"{x:Type Button}"</span>&gt;</span></span><span style="color: black;"> <span style="color: black;">&lt;<span style="color: black;">Setter</span> <span style="color: black;">Property</span>=<span style="color: black;">"Bac<span style="color: black;">公斤</span>round"</span> <span style="color: black;">Value</span>=<span style="color: black;">"Red"</span>/&gt;</span></span><span style="color: black;"> <span style="color: black;">&lt;<span style="color: black;">Setter</span> <span style="color: black;">Property</span>=<span style="color: black;">"Foreground"</span> <span style="color: black;">Value</span>=<span style="color: black;">"White"</span>/&gt;</span></span><span style="color: black;"> <span style="color: black;">&lt;<span style="color: black;">Setter</span> <span style="color: black;">Property</span>=<span style="color: black;">"FontSize"</span> <span style="color: black;">Value</span>=<span style="color: black;">"14"</span>/&gt;</span></span><span style="color: black;"><span style="color: black;">&lt;/<span style="color: black;">Style</span>&gt;</span></span><span style="color: black;"><span style="color: black;">&lt;/<span style="color: black;">Window.Resources</span>&gt;</span></span><span style="color: black;"><span style="color: black;">&lt;<span style="color: black;">Button</span> <span style="color: black;">Style</span>=<span style="color: black;">"{StaticResource RedButtonStyle}"</span> <span style="color: black;">Content</span>=<span style="color: black;">"Click me!"</span>/&gt;</span></span><span style="color: black;">```</span>
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这个示例定义了一个名为"RedButtonStyle"的按钮样式，它将按钮的背景设置为红色，前景设置为白色，字体<span style="color: black;">体积</span>设置为14。<span style="color: black;">而后</span>，该样式被应用到一个按钮上。</p>
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2. 模板</p>
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">模板是一种<span style="color: black;">能够</span>完全自定义和重写控件外观的机制。它不仅<span style="color: black;">能够</span><span style="color: black;">掌控</span>控件的外观，还<span style="color: black;">能够</span>改变控件的内部结构和<span style="color: black;">行径</span>。<span style="color: black;">运用</span>模板<span style="color: black;">能够</span>更好地<span style="color: black;">掌控</span>控件的呈现方式，以满足<span style="color: black;">各样</span>外观和功能<span style="color: black;">需要</span>。要<span style="color: black;">运用</span>模板，<span style="color: black;">能够</span>在XAML文件中定义"ControlTemplate"元素，并在控件上设置"Template"属性。</p>
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">以下是一个简单的模板示例，它定义了一个自定义的按钮模板：</p><span style="color: black;">```xml</span><span style="color: black;"><span style="color: black;">&lt;<span style="color: black;">Window.Resources</span>&gt;</span></span><span style="color: black;"> <span style="color: black;">&lt;<span style="color: black;">ControlTemplate</span> <span style="color: black;">x:Key</span>=<span style="color: black;">"CustomButtonTemplate"</span> <span style="color: black;">TargetType</span>=<span style="color: black;">"{x:Type Button}"</span>&gt;</span></span><span style="color: black;"> <span style="color: black;">&lt;<span style="color: black;">Border</span> <span style="color: black;">Bac<span style="color: black;">公斤</span>round</span>=<span style="color: black;">"Red"</span> <span style="color: black;">BorderThickness</span>=<span style="color: black;">"1"</span> <span style="color: black;">BorderBrush</span>=<span style="color: black;">"Gray"</span>&gt;</span></span><span style="color: black;"> <span style="color: black;">&lt;<span style="color: black;">ContentPresenter</span> <span style="color: black;">HorizontalAlignment</span>=<span style="color: black;">"Center"</span> <span style="color: black;">VerticalAlignment</span>=<span style="color: black;">"Center"</span>/&gt;</span></span><span style="color: black;"> <span style="color: black;">&lt;/<span style="color: black;">Border</span>&gt;</span></span><span style="color: black;"> <span style="color: black;">&lt;/<span style="color: black;">ControlTemplate</span>&gt;</span></span><span style="color: black;"><span style="color: black;">&lt;/<span style="color: black;">Window.Resources</span>&gt;</span></span><span style="color: black;"><span style="color: black;">&lt;<span style="color: black;">Button</span> <span style="color: black;">Template</span>=<span style="color: black;">"{StaticResource CustomButtonTemplate}"</span> <span style="color: black;">Content</span>=<span style="color: black;">"Click me!"</span>/&gt;</span></span><span style="color: black;">```</span>
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这个示例定义了一个名为"CustomButtonTemplate"的按钮模板，它将按钮的背景设置为红色，边框设置为灰色，<span style="color: black;">而后</span>将内容<span style="color: black;">安置</span>在中心。<span style="color: black;">而后</span>，该模板被应用到一个按钮上。</p>
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">总之，样式和模板都是WPF中非常强大的控件外观机制，它们<span style="color: black;">能够</span><span style="color: black;">帮忙</span><span style="color: black;">研发</span>人员更好地管理控件的视觉设计和<span style="color: black;">行径</span>。样式用于定义控件的外观属性，而模板则用于完全自定义和重写控件的外观和<span style="color: black;">行径</span>。</p>
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">倘若</span><span style="color: black;">爱好</span>我的<span style="color: black;">文案</span>，<span style="color: black;">那样</span></span></p>
            <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">“<span style="color: black;">在看</span>”和<span style="color: black;">转发</span>是对我最大的支持！</span></p>
