TextBlock光看名字就知道，就是一個讓你顯示文字的區塊
<TextBlock>This is a
TextBlock</TextBlock>
如果字串過長，字會自動被隱藏
<TextBlock Margin="10"
Foreground="Red">
This is a TextBlock control<LineBreak />
with multiple lines of text.
</TextBlock>
<TextBlock Margin="10"
TextTrimming="CharacterEllipsis" Foreground="Green">
This is a TextBlock control with text that may not be rendered
completely, which will be indicated with an ellipsis.
</TextBlock>
<TextBlock Margin="10"
TextWrapping="Wrap" Foreground="Blue">
This is a TextBlock control with automatically wrapped text, using the
TextWrapping property.
</TextBlock>
<LineBreak /> ： 直接規定這裡要換行，不是很好的作法，較無彈性。
TextTrimming="CharacterEllipsis" ： 超過的字會以...代替，如果使用WordEllipsis，會以單字為單位，就不會有一個字突然被切斷的情形發生。
TextWrapping="Wrap" ： 視位置自動換行，一定會顯示出所有的字出來。
其他功能：
<Bold></Bold> - 粗體
<Italic></Italic> - 斜體
<Underline></Underline> - 下底線
<Hyperlink
RequestNavigate="Hyperlink_RequestNavigate"
NavigateUri="https://www.google.com">link</Hyperlink> - 超連結
Backend會多一個Hyperlink_RequestNavigate()
method，需要實作它
private void
Hyperlink_RequestNavigate(object sender,
System.Windows.Navigation.RequestNavigateEventArgs e)
{
System.Diagnostics.Process.Start(e.Uri.AbsoluteUri);
}
<span></span> - 作用與HTML的span有點相像，可以設定許多的屬性，以便管理
<TextBlock Margin="10" TextWrapping="Wrap">
This <Span FontWeight="Bold">is</Span> a
<Span Background="Silver"
Foreground="Maroon">TextBlock</Span>
with <Span
TextDecorations="Underline">several</Span>
<Span FontStyle="Italic">Span</Span> elements,
<Span Foreground="Blue">
using a <Bold>variety</Bold> of
<Italic>styles</Italic>
</Span>.
</TextBlock>
用C#設格式
public partial class
TextBlockCodeBehindSample : Window
{
public TextBlockCodeBehindSample()
{
InitializeComponent();
TextBlock tb = new TextBlock();
tb.TextWrapping = TextWrapping.Wrap;
tb.Margin = new Thickness(10);
tb.Inlines.Add("An example on ");
tb.Inlines.Add(new Run("the TextBlock control ") { FontWeight
= FontWeights.Bold });
tb.Inlines.Add("using ");
tb.Inlines.Add(new Run("inline ") { FontStyle =
FontStyles.Italic });
tb.Inlines.Add(new Run("text formatting ") { Foreground =
Brushes.Blue });
tb.Inlines.Add("from ");
tb.Inlines.Add(new Run("Code-Behind") { TextDecorations =
TextDecorations.Underline });
tb.Inlines.Add(".");
this.Content = tb;
}
}
