C#如何绑定多个按钮到同一个事件

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

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); }
