c＃WinForm如果選中了動態復選框（從其他功能訪問）

Question

這就是我所擁有的...

private void blablabla()
{
  for (int i=1; i<count+1; i++)
  {
    int item_number = panelBoats.Controls.Count;
    CheckBox chb = new CheckBox();
    chb.Name = "CheckBoxBoat" + i.ToString();
    chb.Text = "Boat " + i.ToString();
    chb.Location = new Point(10, item_number * 15);
    panelBoats.Controls.Add(chb);
  }
}

我希望這是可行的...

private void plotMarker(PaintEventArgs e)
{
    if(CheckBoxBoat0.Checked)
    {
         MessageBox.Show('Yehaaa');
    }
 }

好吧，您可以做的是在班級中提供一個復選框列表

List<CheckBox> myCheckBoxList = new List<CheckBox>();

當您創建復選框時，將其添加到列表中

private void blablabla()
{
    for (int i = 1; i < count + 1; i++)
    {
        int item_number = panelBoats.Controls.Count;
        CheckBox chb = new CheckBox();
        chb.Name = "CheckBoxBoat" + i.ToString();
        chb.Text = "Boat " + i.ToString();
        chb.Location = new Point(10, item_number * 15);
        panelBoats.Controls.Add(chb);

        //Add the checkBox to the list
        myCheckBoxList.add(chb);
    }
}

然后您可以使用列表訪問它

private void plotMarker(PaintEventArgs e)
{
    if (myCheckBoxList[0].Checked)
    {
        MessageBox.Schow('Yehaaa');
    }
}
