private MouseButtons Button;
private long Ticks;
private long TicksDelay = 100000L;

private void btn_Click(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Left)
    {
        if (DateTime.Now.Ticks - Ticks < TicksDelay && Button == MouseButtons.Right)
        {
            //左右键"同时"（先左后右）     

        }
        else
        {
            //左键

        }
    }
    else if (e.Button == MouseButtons.Right)
    {
        if (DateTime.Now.Ticks - Ticks < TicksDelay && Button == MouseButtons.Left)
        {
            //左右键"同时"（先右后左）     

        }
        else
        {
            //右键

        }
    }
    Button = e.Button;
    Ticks = DateTime.Now.Ticks;
