推荐答案

你可以使用:

richTextBox1.SelectionColor = Color.Yellow; richTextBox1.SelectionBackColor = Color.Blue;

选择一个文本集:

richTextBox1.SelectionStart = text_position_in_editor (caret position) richTextBox1.SelectionLength = text_length

然后设置 SelectionColor ...(查看所有以 Selection... 开头的属性)

then set SelectionColor ... (see all properties starting with Selection...)

或者，您可以直接设置包含格式信息的Rtf 属性(或richTextBox1.SelectedRtf).

Or, you can set directly the Rtf property (or richTextBox1.SelectedRtf) which contains formatting info.

在写字板中输入一些文本，更改其格式，将其复制并粘贴到您的 RichTextBox 中，显示属性 Rtf 值，您应该能够更快地了解如何满足您的需求.

Type some text in WordPad, change it's formatting, copy and paste it into your RichTextBox, show the property Rtf value, you should be able to learn faster how to meet your needs.
