You can not do this with a textbox, but you can use a richtextbox: WPF RichTextBox Tutorial
您不能使用文本框执行此操作，但可以使用富文本框： WPF RichTextBox 教程
var textRange = MyRichTextBox.Selection;
var start = MyRichTextBox.Document.ContentStart;
var startPos = start.GetPositionAtOffset(0);
var endPos = start.GetPositionAtOffset(1);
textRange.Select(startPos, endPos);
textRange.ApplyPropertyValue(TextElement.ForegroundProperty, new SolidColorBrush(Colors.Blue));

You can use richtexbox like below: You can even change backcolor for a particular character as well
您可以像下面这样使用richtexbox：您甚至可以更改特定字符的背景颜色
richTextBox1.SelectionStart = characterStartIndex;
richTextBox1.SelectionLength = 1;
richTextBox1.SelectionColor = Color.Red;
richTextBox1.SelectionBackColor = Color.Yellow;
