C#中枚举类型和radiobox关联操作代码
有了enum我们可以列举类型了，有了单选框和复选框我们可以鼠标来选择了。但是编程的时候觉得让两个关联起来，写代码比较麻烦，所以想自动的关联起来。所以我尝试了一下，记录如下。

假如一个星期的enum：
&nbsp&nbsp&nbsp&nbsppublic&nbspenum&nbsp星期
&nbsp&nbsp&nbsp&nbsp{
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp星期一&nbsp=&nbsp0,
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp星期二,
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp星期三,
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp星期四,
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp星期五,
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp星期六,
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp星期天
&nbsp&nbsp&nbsp&nbsp}
关联到7个RadioButton，也就是单选框。
第一步在enum中定义星期一=0；
第二步在初始化函数中如下定义：

public MainForm()
        {
            //
            // The InitializeComponent() call is required for Windows Forms designer support.
            //
            InitializeComponent();
            
            //
            // TODO: Add constructor code after the InitializeComponent() call.
            //
            int idx = 0;
            foreach(Control c in groupBox1.Controls)
            {
                if(c is RadioButton)
                {
                    ((RadioButton)c).Text  = ((星期)idx).ToString();
                    ((RadioButton)c).Tag = ((星期)idx);
                    idx++;
                }
            }
        }

第三步添加测试代码：

void Button1Click(object sender, EventArgs e)
        {
            foreach(Control c in groupBox1.Controls)
            {
                if(c is RadioButton)
                {
                    if(((RadioButton)c).Checked == true)
                    {
                        星期 week = (星期)(((RadioButton)c).Tag);
                        MessageBox.Show(week.ToString());
                    }
                }
            }
        }

注意：groupbox中控件的顺序在这些代码中控制，假如发现顺序不对，就要重新调整一下。

            this.groupBox1.Controls.Add(this.radioButton1);
            this.groupBox1.Controls.Add(this.radioButton2);
            this.groupBox1.Controls.Add(this.radioButton3);
            this.groupBox1.Controls.Add(this.radioButton4);
            this.groupBox1.Controls.Add(this.radioButton5);
            this.groupBox1.Controls.Add(this.radioButton6);
            this.groupBox1.Controls.Add(this.radioButton7);
