关于多控件调用同一个事件的问题

关于多控件调用同一个事件的问题，看到网上有道题：

如果按照每个控件都单独调用的话，很明显写多很多代码，有什么方法能省去多余的代码都调用同一个方法吗？

普通的单独调用的代码如下，谁看看怎么省去多余的代码

  1 using System;
  2 using System.Collections.Generic;
  3 using System.ComponentModel;
  4 using System.Data;
  5 using System.Drawing;
  6 using System.Linq;
  7 using System.Text;
  8 using System.Threading.Tasks;
  9 using System.Windows.Forms;

经好心网友提供意见，写成这样

1 private void FontFamily_CheckedChanged(object sender, EventArgs e)
2 {
3 RadioButton radio = sender as RadioButton;
4 txtShow.Font = new Font(radio.Text, txtShow.Font.Size, txtShow.Font.Style);
5 }

然后到前端的字体那四个radiobutton 的属性--事件里面把checkedchanged 事件都选择这个方法。

 1         //字号大小
 2         private void FontFamily1_CheckedChanged(object sender, EventArgs e)
 3         {
 4             RadioButton radio = sender as RadioButton;
 5             txtShow.Font = new Font(txtShow.Font.FontFamily, Convert.ToInt32(radio.Text), txtShow.Font.Style);
 6         }
 7         //颜色
 8         private void FontFamily2_CheckedChanged(object sender, EventArgs e)
 9         {
10             RadioButton radio = sender as RadioButton;
11             if (radio.Text == "红")
12             {
13                 txtShow.ForeColor = System.Drawing.Color.Red;
14             }
15             else if (radio.Text == "黄")
16             {
17                 txtShow.ForeColor = System.Drawing.Color.Yellow;
18             }
19             else if (radio.Text == "蓝")
20             {
21                 txtShow.ForeColor = System.Drawing.Color.Blue;
22             }
23         }

CheckBox的方法：

先在窗体加载的时候这样设置：

 1         private void Form1_Load(object sender, EventArgs e)
 2         {
 3             cbxBold.Tag = (int)FontStyle.Bold;
 4             //试下cbxItalic.Tag还能指向其他类型不
 5             //cbxItalic.Tag = Font.Style;
 6             cbxItalic.Tag = (int)FontStyle.Italic;
 7             cbxStrickout.Tag = (int)FontStyle.Strikeout;
 8             cbxUnderline.Tag = (int)FontStyle.Underline;
 9             //MessageBox.Show(cbxUnderline.Tag.ToString());
10         }

然后让所有CheckBox多选框都把CheckedChanged事件指向下面这个方法

 1 　　　　　private void Style_CheckedChanged(object sender, EventArgs e)
 2         {
 3             //CheckBox cb = new CheckBox();
 4             CheckBox cb = sender as CheckBox;
 5             FontStyle style = (FontStyle)(Convert.ToInt32(cb.Tag));
 6             //FontStyle style = (FontStyle)4;
 7             if (cb.Checked)
 8             {
 9                 txtShow.Font = new Font(txtShow.Font, txtShow.Font.Style | style);
10             }
11             else
12             {
13                 txtShow.Font = new Font(txtShow.Font, txtShow.Font.Style ^ style);
14             }
15             //MessageBox.Show(style.ToString()); 
16         }
