foreach (Control c in Controls) { if (c is CheckBox) { ((CheckBox) c).Checked = pdwPortVal & (1 << c.TabIndex)) } } index 也可以放在 Tag 中。

你可以把3组checkbox放入groupbox, panel 等container中，checkbox的索引值放入 tabindex或tag中，则程序很简洁。

            //遍历CheckBox方法1
            foreach (Control c in groupBox1.Controls)//遍历groupBox1内的所有控件
            {
                if (c is CheckBox)//只遍历CheckBox控件
                {
                    ((CheckBox)c).Checked = (pdwPortVal & (1 << (checkBox8.TabIndex - c.TabIndex))) != 0;
                }
            }
            //遍历CheckBox方法2
            /*
            for (int i = 8; i >= 1; i--)
            {
                ((CheckBox)this.Controls.Find("checkBox" + i, true)[0]).Checked = (pdwPortVal & (1 << (8 - i))) != 0;
            }
            */
/*
            //遍历CheckBox方法3
            for (int i = 0; i < 8; i++)
            {
                switch (i)
                {
                    case 0:
                        checkBox8.Checked = (pdwPortVal & (1 << i)) != 0;
                        break;
                    case 1:
                        checkBox7.Checked = (pdwPortVal & (1 << i)) != 0;
                        break;
                    case 2:
                        checkBox6.Checked = (pdwPortVal & (1 << i)) != 0;
                        break;
                    case 3:
                        checkBox5.Checked = (pdwPortVal & (1 << i)) != 0;
                        break;
                    case 4:
                        checkBox4.Checked = (pdwPortVal & (1 << i)) != 0;
                        break;
                    case 5:
                        checkBox3.Checked = (pdwPortVal & (1 << i)) != 0;
                        break;
                    case 6:
                        checkBox2.Checked = (pdwPortVal & (1 << i)) != 0;
                        break;
                    case 7:
                        checkBox1.Checked = (pdwPortVal & (1 << i)) != 0;
                        break;
                }
            }
