枚举操作的常用方法，包括获得枚举的value,name,description

public enum SendInfoStateEnum
    {

　　  [Description("等待提交")]
        等待提交 = 1,

　　　[Description("等待审核")]
        等待审核 = 2,
        审核成功 = 3,
        审核失败 = 4,
        正在发送 = 5,

}

绑定枚举到dropdownlist方法如下：

调用如：BindEnumToDropdownList(typeof(SendInfoStateEnum), ddlSendState, new ListItem("--请选择--", "-1"), "-1");

重点是Enum.GetValues(enumType)、Enum.GetName(enumType, i) 2个方法。

/// <summary>
    /// 绑定枚举到dropdownlist
    /// </summary>
    /// <param name="enumType">枚举类型</param>
    /// <param name="ddl">dropdownlist</param>
    /// <param name="li">初始化第一个选项,可为null</param>
    /// <param name="selectValue">选中项的值</param>
    public static void BindEnumToDropdownList(Type enumType, DropDownList ddl, ListItem firstItem, string selectValue)
    {
        ddl.Items.Clear();
        if (firstItem != null)
        {
            ddl.Items.Add(firstItem);
        }

        foreach (int i in Enum.GetValues(enumType))
        {
            ListItem li2 = new ListItem(Enum.GetName(enumType, i), i.ToString());
            if (li2.Value.Equals(selectValue))
            {
                li2.Selected = true;
            }
            ddl.Items.Add(li2);
        }
    }

 

 获取枚举值的描述标签方法：

调用如：GetDescriptionByName(SendInfoStateEnum.等待提交);

/// <summary>
        /// get enum description by name
        /// </summary>
        /// <typeparam name="T">enum type</typeparam>
        /// <param name="enumItemName">the enum name</param>
        /// <returns>description string</returns>
        public static string GetDescriptionByName<T>(this T enumItemName)
        {
            FieldInfo fi = enumItemName.GetType().GetField(enumItemName.ToString());

            DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(
                typeof(DescriptionAttribute), false);

            if (attributes != null && attributes.Length > 0)
            {
                return attributes[0].Description;
            }
            else
            {
                return enumItemName.ToString();
            }
        }
