這篇文章主要介紹了C#如何綁定多個按鈕到同一個事件，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

綁定多個按鈕到同一個事件

1.添加代碼

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

2.選擇你要添加代碼的控件

右鍵–屬性–找到click這個事件，讓后選擇clauseElementClicked這個事件就可以了。

多個控件有同一個事件,優(yōu)化

先自己聲明方法,再用事件調用

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);
           
        }
