Style Style Style Style Class

定義

在某型別的各執行個體間啟用屬性、資源與事件處理常式的共用。Enables the sharing of properties, resources, and event handlers between instances of a type.

public ref class Style : System::Windows::Threading::DispatcherObject, System::Windows::Markup::IAddChild, System::Windows::Markup::INameScope, System::Windows::Markup::IQueryAmbient
[System.Windows.Localizability(System.Windows.LocalizationCategory.Ignore)]
[System.Windows.Markup.ContentProperty("Setters")]
[System.Windows.Markup.DictionaryKeyProperty("TargetType")]
public class Style : System.Windows.Threading.DispatcherObject, System.Windows.Markup.IAddChild, System.Windows.Markup.INameScope, System.Windows.Markup.IQueryAmbient

範例

下列範例顯示會影響Background Control之屬性的樣式宣告。The following example shows a style declaration that will affect the Background property of a Control.

<Style x:Key="Style1">
  <Setter Property="Control.Background" Value="Yellow"/>
</Style>

若要套用上述樣式, 請執行下列動作:To apply the above style, do the following:

<Label Content="Yellow Background" Style="{StaticResource Style1}" />

您也可以使用TargetType屬性, 將樣式套用至指定類型的所有元素。You can also apply styles to all elements of a given type by using the TargetType property. 將目標型別新增至樣式, 表示您不再需要使用ClassName.PropertyName語法來完整限定您所設定的屬性。Adding the target type to the style means that you no longer have to fully qualify the property you are setting with the ClassName.PropertyName syntax. 下列範例會定義將套用至每個TextBlock元素的樣式。The following example defines a style that will be applied to every TextBlock element.

<Style TargetType="{x:Type TextBlock}">
  <Setter Property="FontFamily" Value="Segoe Black" />
  <Setter Property="HorizontalAlignment" Value="Center" />
  <Setter Property="FontSize" Value="12pt" />
  <Setter Property="Foreground" Value="#777777" />
</Style>

注意

許多WPFWPF控制項都是由其他WPFWPF控制項的組合所組成, 因此, 建立適用于類型之所有控制項的樣式可能會有廣泛的影響。Many WPFWPF controls consist of a combination of other WPFWPF controls, so creating a style that applies to all controls of a type can have broad impact. 例如, 如果您TextBlock建立以Canvas中的控制項為目標的樣式, 則樣式會套用至畫布中TextBlock的所有TextBlock控制項, 即使是另一個控制項的一部分, 例如ListBoxFor instance, if you create a style that targets the TextBlock controls in a Canvas, the style is applied to all TextBlock controls in the canvas, even if the TextBlock is part of another control, such as a ListBox.

如需如何從定義的樣式延伸或繼承的詳細資訊, 請BasedOn參閱頁面。For information on how to extend or inherit from a defined style, see the BasedOn page.

備註

您可以Style在衍生自FrameworkElementFrameworkContentElement的任何專案上設定。You can set a Style on any element that derives from FrameworkElement or FrameworkContentElement. 樣式最常宣告為Resources區段內的資源。A style is most commonly declared as a resource inside the Resources section. 因為樣式是資源, 所以它們會遵守適用于所有資源的相同範圍規則, 因此您宣告樣式會影響可以套用的位置。Because styles are resources, they obey the same scoping rules that apply to all resources, so where you declare a style affects where it can be applied. 例如, 如果您在應用程式定義XAMLXAML檔的根項目中宣告樣式, 則可以在應用程式中的任何位置使用樣式。If, for instance, you declare the style in the root element of your application definition XAMLXAML file, the style can be used anywhere in your application. 如果您要建立導覽應用程式, 並在其中一個應用程式的XAMLXAML檔案中宣告樣式, 則樣式只能用在該XAMLXAML檔案中。If you are creating a navigation application and declare the style in one of the application's XAMLXAML files, the style can be used only in that XAMLXAML file. 如需資源範圍規則的詳細資訊, 請參閱XAML 資源For more information on scoping rules for resources, see XAML Resources.

樣式宣告是由包含一Style或多個Setter物件之集合的物件所組成。The style declaration consists of a Style object that contains a collection of one or more Setter objects. Setter個都是Property由和Value組成。Each Setter consists of a Property and a Value. 屬性是要套用樣式之元素的屬性名稱。The property is the name of the property of the element the style is to apply to. 在樣式宣告為資源之後, 就可以像任何其他資源一樣地加以參考。After the style is declared as a resource, it can then be referenced just like any other resource.

注意

如果 setter 集合中有一個以上的 setter 具有相同Property的屬性值, 則會使用最後宣告的 setter。If there is more than one setter in the setter collection with the same Property property value, the setter that is declared last is used. 同樣地, 如果您在樣式中設定相同屬性的值, 並直接在專案上設定, 則在元素上設定的值會直接優先。Similarly, if you set a value for the same property in a style and on an element directly, the value set on the element directly takes precedence.
