枚举与字符串的互化示例

using System;

public class ParseTest
{
    enum Colors { Red = 1, Green = 2, Blue = 4, Yellow = 8 };

    public static void Main()
    {
        Console.WriteLine("The entries of the Colors Enum are:");
        foreach (string colorName in Enum.GetNames(typeof(Colors)))
        {
            Console.WriteLine("{0}={1}", colorName,
                                         Convert.ToInt32(Enum.Parse(typeof(Colors), colorName)));
        }
        Console.WriteLine();
        Colors myOrange = (Colors)Enum.Parse(typeof(Colors), "Red, Yellow");
        Console.WriteLine("The myOrange value {1} has the combined entries of {0}",
                           myOrange, Convert.ToInt64(myOrange));
    }
}

/*
输出结果：

The entries of the Colors Enum are:
Red=1
Green=2
Blue=4
Yellow=8

The myOrange value 9 has the combined entries of Red, Yellow
