RichTextBox控件

RichTextBox控件允许用户输入和编辑文本的同时提供了比普通的TextBox控件更高级的格式特征

//color在c#中是个枚举enum

蓝色按钮：在蓝色按钮注册click事件后，richtextbox1.selectioncolor=color.blue；

红色按钮：在红色按钮注册click事件后，RichTextBox1.selectionColor=color.Red；

隶属18按钮；在注册click事件后，RichTextBox1.selectionFont=new font（“隶属”，18）；

楷书18按钮；在注册事件后，RichTextBox1.selectionFont=new font（“楷书”，20）；

项目符号；在注册事件后，RichTextBox1.selectionBullet=true；

底纹；在注册事件后，RichTextBox1.selectionBackColor=color.gray；//底纹就是背景颜色

复原：//要看看richtextbox以前的字体是什么的，之后直接赋值就好了

RichTextBox1.selectionFont=new font（“宋体”，15）；

RichTextBox1.selectionColor=color.white；//上面所有的都要写回来

 

     private void blue_Click(object sender, EventArgs e)

        {

            //richb.选择颜色=颜色中的蓝色

            Richb.SelectionColor = Color.Blue;

        }

 

        private void red_Click(object sender, EventArgs e)

        {

            Richb.SelectionColor = Color.Red;

        }

        }

 

        private void micr20_Click(object sender, EventArgs e)

        {

            Richb.SelectionFont = new Font("微软雅黑", 18);
