checkbox问题

Question

 foreach(Control c in gbRecdtl.Controls)
 {
        if(c is CheckBox)
        {
            if(??)
              sqltext += "d."+c.Text + ",";
        }
 }
我现在想把十几个checkbox控件放到groupbox容器里面，再通过循环判断groupbox里面的控件是不是checkbox，接着我还想判断那个checkbox是否被选择中了（不知道怎么写了）。

Answer 1

你不是都找到c了吗，那就((CheckBox)c).Checked

Answer 2

foreach (RadioButton rb in temp_GB.Controls)
            {
                if (rb.Checked)
                {
                    switch (rb.Text)
                    {
                        case "A股":
                            flag = 0;
                            break;
                        case "B股":
                            flag = 1;
                            break;
                        case "HK股":
                            flag = 2;
                            break;
                        default:
                            flag = 0;
                            break;
                    }
                    break;
                }
                else
                {
                    continue;
                }
            }
