推荐答案
试试这个:
TextRange rangeOfText1 = new TextRange(richTextBox.Document.ContentEnd, richTextBox.Document.ContentEnd);
rangeOfText1.Text = "Text1 ";
rangeOfText1.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Blue);
rangeOfText1.ApplyPropertyValue(TextElement.FontWeightProperty, FontWeights.Bold);
TextRange rangeOfWord = new TextRange(richTextBox.Document.ContentEnd, richTextBox.Document.ContentEnd);
rangeOfWord.Text = "word ";
rangeOfWord.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Red);
rangeOfWord.ApplyPropertyValue(TextElement.FontWeightProperty, FontWeights.Regular);
TextRange rangeOfText2 = new TextRange(richTextBox.Document.ContentEnd, richTextBox.Document.ContentEnd);
rangeOfText2.Text = "Text2 ";
rangeOfText2.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Blue);
rangeOfText2.ApplyPropertyValue(TextElement.FontWeightProperty, FontWeights.Bold);
或这样的:
public TestWindow()
{
InitializeComponent();
this.paragraph = new Paragraph();
rich1.Document = new FlowDocument(paragraph);
var from = "user1";
var text = "chat message goes here";
paragraph.Inlines.Add(new Bold(new Run(from + ": "))
{
Foreground = Brushes.Red
});
paragraph.Inlines.Add(text);
paragraph.Inlines.Add(new LineBreak());
this.DataContext = this;
}
private Paragraph paragraph;
