Answer 1

试试这个

private int MonthValue = 0;
private bool bChanged = false;
private void Form1_Load(object sender, EventArgs e)
{
    MonthValue = monthCalendar1.TodayDate.Month;
}
private void monthCalendar1_DateChanged(object sender, DateRangeEventArgs e)
{

    if (MonthValue != monthCalendar1.SelectionStart.Month)
    {
        //changed
        bChanged = true;
        MonthValue = monthCalendar1.SelectionStart.Month;
    }
    else
    {
        //not changed
        bChanged = false;
    }
}
