本文通过一个简单的WPF应用程序示例展示了如何使用TextBlock元素进行文本格式化，包括字体大小、颜色、斜体、粗体等效果，并介绍了如何为Run对象添加鼠标事件来动态改变文本样式。

using System; using System.Windows; using System.Windows.Controls; using System.Windows.Input; using System.Windows.Media; using System.Windows.Documents; namespace Cloud.FormatTheText { public class FormatTheText : Window { [STAThread] public static void Main() { Application app = new Application(); app.Run(new FormatTheText()); } public FormatTheText() { this.Title = "Cloud Orz"; TextBlock txt = new TextBlock(); txt.FontSize = 32; Run run = new Run("This is some "); run.MouseDown += new MouseButtonEventHandler(run_MouseDown); run.Foreground = Brushes.Red; txt.Inlines.Add(run); txt.Inlines.Add(new Italic(new Run("italic"))); txt.Inlines.Add(" text, and this is some "); txt.Inlines.Add(new Bold(new Run("bold"))); txt.Inlines.Add(" text, and this is some "); txt.Inlines.Add(new Bold(new Italic(new Run("bold italic")))); txt.Inlines.Add(" text."); txt.TextWrapping = TextWrapping.Wrap; this.Content = txt; } void run_MouseDown(object sender, MouseButtonEventArgs e) { Run run = sender as Run; if (e.ChangedButton == MouseButton.Left) run.FontStyle = run.FontStyle == FontStyles.Italic ? FontStyles.Normal : FontStyles.Italic; if (e.ChangedButton == MouseButton.Right) run.FontWeight = run.FontWeight == FontWeights.Bold ? FontWeights.Normal : FontWeights.Bold; } } }

这些代码,就是很单纯的建立一个TextBlock,然后放进Window的Content property

若是直接将string放入Content property, 将会先建立一个TextBlock,以显示出字串

同时示范了,如何安装事件到Run对象中
