本次练习在Unity工程中实现。

C#遍历枚举的方法如下：

枚举可用来存储字符串与数字的值对，相当于一个对照表

常用方法：GetName(),GetValue(),Parse()

头文件：using System;

  /// <summary>
    /// 枚举星期
    /// </summary>
    public enum Weekdays { Saturday, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday };

    /// <summary>
    /// 遍历枚举
    //// 访法一
    /// </summary>
    private void ergodicEnum1()
    {
        Debug.Log("-------------------------------------------------------------------");

        foreach (int myday in Enum.GetValues(typeof(Weekdays)))
        {
            /// 枚举名字
            string name = Enum.GetName(typeof(Weekdays), myday);
            /// 枚举的值
            int value = myday;

            Debug.Log(string.Format("名字 = {0},值 = {1}", name, myday));
        }

        Debug.Log("-------------------------------------------------------------------");
    }

    /// <summary>
    /// 枚举颜色
    /// </summary>
    public enum Colors { Red = 1, Green = 2, Blue = 4, Yellow = 8 };
     
    /// <summary>
    /// 遍历枚举
    //// 访法二
    /// </summary>
    private void ergodicEnum2()
    {
        Type color = typeof(Colors);

        Debug.Log("-------------------------------------------------------------------");

        foreach (string c in Enum.GetNames(color))
        {
            Debug.Log(string.Format("{0,-11}= {1}",c, Enum.Format(color, Enum.Parse(color, c), "d")));
        }

        Debug.Log("-------------------------------------------------------------------");

        foreach (string c in Enum.GetNames(typeof(Colors)))
        {
            Debug.Log(string.Format("{0,-11}= {1}", c, Enum.Format(color, Enum.Parse(color, c), "d")));
        }

        Debug.Log("-------------------------------------------------------------------");

        Colors myColors = Colors.Red | Colors.Green | Colors.Blue | Colors.Yellow;
        Debug.Log(string.Format("myColors holds a combination of colors. Namely: {0}", myColors));

        Debug.Log("-------------------------------------------------------------------");
    }
