C#中如何将combox中的下拉项和一个枚举中的各项进行绑定

public enum StoreSite
    {
        /// <summary>
        /// 未知
        /// </summary>
        [EnumTitle("未知")]
        None = 0,
        /// <summary>
        /// 北京
        /// </summary>
        [EnumTitle("北京")]
        Beijing = 1,
        /// <summary>
        /// 上海
        /// </summary>
        [EnumTitle("上海")]
        Shanghai = 2,
        /// <summary>
        /// 深圳
        /// </summary>
        [EnumTitle("深圳")]
        Shenzhen = 3,
        /// <summary>
        /// 香港
        /// </summary>
        [EnumTitle("香港")]
        Hongkong = 4
    }

namespace ProductManage

    public partial class AddDataFrame : Form
    {
        public AddDataFrame()
        {
            InitializeComponent();            
            #region 数据的初始化
            foreach (string s in Enum.GetNames(typeof(StoreSite)))
            {

                {
                    this.comb_storesite.Items.Add(s);
