Question

在TextBlock对象中，您可以格式化XAML中的文本，如下所示：

<TextBlock>
    <Bold>bold text</Bold> random non bold next
</TextBlock>

如何以编程方式执行“Bold”标记？

我尝试将它们放在text属性中，然后将它们打印出来（标签以文本形式打印）。

Answer 1

Visual Basic版本：

Dim tb As New TextBlock

Dim b As New Bold
b.Inlines.Add(New Run("bold text"))

tb.Inlines.Add(b)
tb.Inlines.Add(New Run("random non bold text"))

C＃版本：

TextBlock tb = new TextBlock();
var bold = new Bold(new Run("Bold Text"));
tb.Inlines.Add(bold);

var normal = new Run("Normal Text"));
tb.Inlines.Add(normal);

Answer 2

以下是MSDN网站上的代码，我认为这将有所帮助（http://msdn.microsoft.com/en-us/library/system.windows.controls.textblock.aspx）。

XAML

<TextBlock Name="textBlock1" TextWrapping="Wrap">
  <Bold>TextBlock</Bold> is designed to be <Italic>lightweight</Italic>,
  and is geared specifically at integrating <Italic>small</Italic> portions
  of flow content into a UI.
</TextBlock>
<Button Width="100" Margin="10">Click Me</Button>
<TextBlock  Name="textBlock2" 
  TextWrapping="Wrap" Background="AntiqueWhite" TextAlignment="Center"
>
  By default, a TextBlock provides no UI beyond simply displaying its contents.
</TextBlock>
<Button Width="100" Margin="10">Click Me</Button>

C＃

TextBlock textBlock1 = new TextBlock();
TextBlock textBlock2 = new TextBlock();

textBlock1.TextWrapping = textBlock2.TextWrapping = TextWrapping.Wrap;
textBlock2.Background = Brushes.AntiqueWhite;
textBlock2.TextAlignment = TextAlignment.Center;

textBlock1.Inlines.Add(new Bold(new Run("TextBlock")));
textBlock1.Inlines.Add(new Run(" is designed to be "));
textBlock1.Inlines.Add(new Italic(new Run("lightweight")));
textBlock1.Inlines.Add(new Run(", and is geared specifically at integrating "));
textBlock1.Inlines.Add(new Italic(new Run("small")));
textBlock1.Inlines.Add(new Run(" portions of flow content into a UI."));

textBlock2.Text =
    "By default, a TextBlock provides no UI beyond simply displaying its contents.";

试试这个：

textBlock1.FontWeight = Windows.UI.Text.FontWeights.Bold;
