推荐答案

您将需要学习一些RTF规范.然后迭代输入文本并设置打开和关闭rtf标签以设置颜色.另外，请记住，如果添加了rtf标签，则需要验证是否已添加标签，这样就不会多次在特定字符周围添加相同的标签.

如果还有另一种方法，我不知道.几年来我没有使用Richtext框，所以也许还有另一种方法?

You will need to learn some RTF specifications. Then iterate the input text and set opening and closing rtf tags to set the color. Also, keep in mind that if you have added the rtf tags you will need to verify if you have already added a tag so you aren''t adding the same tags around specific characters multiple times.

If there is another way I am not aware of it. I haven''t used Richtext box in a couple years so maybe there is another way???
