文本框的文字颜色变化 [英] textbox text color change

问题描述

和我想改变文字的颜色，但在所有的文字部分。例如，从 / * 到 * / 像在Visual Studio中的意见？

I have textbox textbox1 and I want to change text color, but in the part of all text. For example from /* to */ like comments in visual studio?

我怎样才能做到这一点。

How I can do this?

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;
