C# notifyIcon里的单击事件怎么判断是鼠标左键还是右键点的

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.CenterToScreen();
}

private void Form1_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left && e.Clicks == 1)
{
this.label1.Text = "您单击了鼠标左键！";
}
else if (e.Button == MouseButtons.Right && e.Clicks == 1)
{
this.label1.Text = "您单击了鼠标右键！";
}
}

private void Form1_MouseDoubleClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left && e.Clicks == 2)
{
this.label1.Text = "您双击了鼠标左键！";
}
else if (e.Button == MouseButtons.Right && e.Clicks == 2)
