C#如何绑定多个按钮到同一个事件

绑定多个按钮到同一个事件

1.添加代码

private void clauseElementClicked(object sender, EventArgs e)
{undefined
textBoxWhereClause.SelectedText = ((Button)sender).Text;
}

2.选择你要添加代码的控件

右键–属性–找到click这个事件，让后选择clauseElementClicked这个事件就可以了。 

 多个控件有同一个事件,优化

先自己声明方法,再用事件调用

public void borderS3D(object sender,EventArgs e)
       {
              ((PictureBox)sender).BorderStyle=BorderStyle.Fixed3D;        
       } public void borderSNo(object sender, EventArgs e)
       {
           ((PictureBox)sender).BorderStyle = BorderStyle.None;
       }

public FormMain()
       {
           InitializeComponent();
           pictureBox1.MouseHover += new  EventHandler(borderS3D);
           pictureBox1.MouseLeave += new EventHandler(borderSNo);
           pictureBox2.MouseHover += new EventHandler(borderS3D);
           pictureBox2.MouseLeave += new EventHandler(borderSNo);
           pictureBox3.MouseHover += new EventHandler(borderS3D);
           pictureBox3.MouseLeave += new EventHandler(borderSNo);
           pictureBox4.MouseHover += new EventHandler(borderS3D);
           pictureBox4.MouseLeave += new EventHandler(borderSNo);
           pictureBox5.MouseHover += new EventHandler(borderS3D);
           pictureBox5.MouseLeave += new EventHandler(borderSNo);
           pictureBox6.MouseHover += new EventHandler(borderS3D);
           pictureBox6.MouseLeave += new EventHandler(borderSNo);
           pictureBox7.MouseHover += new EventHandler(borderS3D);
           pictureBox7.MouseLeave += new EventHandler(borderSNo);
           pictureBox8.MouseHover += new EventHandler(borderS3D);
           pictureBox8.MouseLeave += new EventHandler(borderSNo);
           pictureBox9.MouseHover += new EventHandler(borderS3D);
           pictureBox9.MouseLeave += new EventHandler(borderSNo);
           pictureBox10.MouseHover += new EventHandler(borderS3D);
           pictureBox10.MouseLeave += new EventHandler(borderSNo);
           pictureBox11.MouseHover += new EventHandler(borderS3D);
           pictureBox11.MouseLeave += new EventHandler(borderSNo);

}
