下列範例示範如何建立四 Button 個控制項，並將 Content 設定為下列其中一項：

• 字串。

• DateTime 物件。

• UIElement 物件。

• Panel包含其他 UIElement 物件的控制項。

注意

雖然範例的 Extensible Application Markup Language (XAML) 版本可以使用 <Button.Content> 每個按鈕內容周圍的標記，但並非必要。 如需詳細資訊，請參閱 XAML 概觀 (WPF) 。

<!--Create a Button with a string as its content.-->
<Button>This is string content of a Button</Button>

<!--Create a Button with a DateTime object as its content.-->
<Button xmlns:sys="clr-namespace:System;assembly=mscorlib">
  <sys:DateTime>2004/3/4 13:6:55</sys:DateTime>
</Button>

<!--Create a Button with a single UIElement as its content.-->
<Button>
  <Rectangle Height="40" Width="40" Fill="Blue"/>
</Button>

<!--Create a Button with a panel that contains multiple objects 
as its content.-->
<Button>
  <StackPanel>
    <Ellipse Height="40" Width="40" Fill="Blue"/>
    <TextBlock TextAlignment="Center">Button</TextBlock>
  </StackPanel>
</Button>

// Create a Button with a string as its content.
Button stringContent = new Button();
stringContent.Content = "This is string content of a Button";

// Create a Button with a DateTime object as its content.
Button objectContent = new Button();
DateTime dateTime1 = new DateTime(2004, 3, 4, 13, 6, 55);

objectContent.Content = dateTime1;

// Create a Button with a single UIElement as its content.
Button uiElementContent = new Button();

Rectangle rect1 = new Rectangle();
rect1.Width = 40;
rect1.Height = 40;
rect1.Fill = Brushes.Blue;
uiElementContent.Content = rect1;

// Create a Button with a panel that contains multiple objects 
// as its content.
Button panelContent = new Button();
StackPanel stackPanel1 = new StackPanel();
Ellipse ellipse1 = new Ellipse();
TextBlock textBlock1 = new TextBlock();

ellipse1.Width = 40;
ellipse1.Height = 40;
ellipse1.Fill = Brushes.Blue;

textBlock1.TextAlignment = TextAlignment.Center;
textBlock1.Text = "Button";

stackPanel1.Children.Add(ellipse1);
stackPanel1.Children.Add(textBlock1);

panelContent.Content = stackPanel1;

' Add a string to a button.
Dim stringContent As New Button()
stringContent.Content = "This is string content of a Button"

' Add a DateTime object to a button.
Dim objectContent As New Button()
Dim dateTime1 As New DateTime(2004, 3, 4, 13, 6, 55)

objectContent.Content = dateTime1

' Add a single UIElement to a button.
Dim uiElementContent As New Button()

Dim rect1 As New Rectangle()
rect1.Width = 40
rect1.Height = 40
rect1.Fill = Brushes.Blue
uiElementContent.Content = rect1

' Add a panel that contains multpile objects to a button.
Dim panelContent As New Button()
Dim stackPanel1 As New StackPanel()
Dim ellipse1 As New Ellipse()
Dim textBlock1 As New TextBlock()

ellipse1.Width = 40
ellipse1.Height = 40
ellipse1.Fill = Brushes.Blue

textBlock1.TextAlignment = TextAlignment.Center
textBlock1.Text = "Button"

stackPanel1.Children.Add(ellipse1)
stackPanel1.Children.Add(textBlock1)

panelContent.Content = stackPanel1

下圖顯示上一個範例中建立的四個按鈕。

備註

Content因為 屬性的類型是 Object ，所以您可以放入 ContentControl 的內容沒有任何限制。 會 Content 由 ContentPresenter ，其位於 的 ContentControl 中 ControlTemplate 。 ContentControlWPF 中的每個類型在其預設 ControlTemplate 中都有 ContentPresenter 。 如需顯示 Content 方式 ContentPresenter 的詳細資訊，請參閱 ContentPresenter 。
