推荐答案

这是不是最好的code，但我希望你的想法：

This is not the best code, but I hope you get the idea:

public Form1()
{
    InitializeComponent();
    monthCalendar1.MaxSelectionCount = 1;
}

private void textBox1_Enter(object sender, EventArgs e)
{
    monthCalendar1.Visible = true;
}

private void textBox1_Leave(object sender, EventArgs e)
{
    if (!monthCalendar1.Focused)
        monthCalendar1.Visible = false;
}

private void monthCalendar1_DateSelected(object sender, DateRangeEventArgs e)
{
    var monthCalendar = sender as MonthCalendar;
    textBox1.Text = monthCalendar.SelectionStart.ToString();
}

private void monthCalendar1_Leave(object sender, EventArgs e)
{
    var monthCalendar = sender as MonthCalendar;
    monthCalendar.Visible = false;
}

首先，将 MaxSelectionCount 为您MonthCalendar控件。接下来，添加事件侦听器留下的焦点和获得焦点。 如果你没有得到它的工作，我可以提供样品解决方案，我测试了它。

First, you set the MaxSelectionCount for you monthCalendar control. Next, you adding event listeners for leaving focus and gaining focus. If you don't get it working, I can provide sample solution where I tested it.
