在richtextbox中更改所选文本的字体和颜色 [英] Changing font and colour of selected text in richtextbox

问题描述

您好

您能否解释一下如何在RichTextBox中更改所选文本的字体和颜色？我找了很久，没有找到任何解决方案。只有如何更改整个TextBox的字体，这不是我想要的。如果我可以用新字体将文本保存到文件中，那将是理想的选择：

感谢您提供任何帮助



编辑：我做了一些实验

Hello
Can you please explain me how to change font and colour of selected text in RichTextBox? I was searching for long time and didn't find any solution. Only how to change font of entire TextBox and that's not what I want. If I could save the text to file with a new font it would be ideal :)
Thanks for any kind of help

I've done some experimenting

FontDialog fd1 = new FontDialog();

 private void edit_Click(object sender, EventArgs e)
 {
     fd1.Font = textbox.SelectionFont;

     if(fd1.ShowDialog() != DialogResult.Cancel)
     {
       textbox.Font = fd1.Font;
     }
 }

但看起来它用默认字体

but it looks like it saves it with the default font

推荐答案

您需要使用属性 SelectionStart 和 SelectionLength 选择文档的某些部分。然后，使用 SelectionColor ， SelectionBackColor 之类的属性等。

You need to select some part of document using properties SelectionStart and SelectionLength. Then, use the properties like SelectionColor, SelectionBackColor and the like.
