C# 枚举、字符串、值的相互转换

using System;

class Program
{
    public enum Color
    {
        Red = 0xff0000,
        Orange = 0xFFA500,
        Yellow = 0xFFFF00,
        Lime = 0x00FF00,
        Cyan = 0x00FFFF,
        Blue = 0x0000FF,
        Purple = 0x800080
    }

    static void Main(string[] args)
    {
        Color color = Color.Blue;
        string colorString = " Blue";
        int colorValue = 0x0000FF;

        // 枚举转字符串
        string enumStringOne = color.ToString(); //效率低,不推荐
        string enumStringTwo = Enum.GetName(typeof(Color), color);//推荐

        // 枚举转值
        int enumValueOne = color.GetHashCode();
        int enumValueTwo = (int)color;
        int enumValueThree = Convert.ToInt32(color);

        // 字符串转枚举
        Color enumOne = (Color)Enum.Parse(typeof(Color), colorString);

        // 字符串转值
        int enumValueFour = (int)Enum.Parse(typeof(Color), colorString);

        // 值转枚举
        Color enumTwo = (Color)colorValue;
        Color enumThree = (Color)Enum.ToObject(typeof(Color), colorValue);

        // 值转字符串
        string enumStringThree = Enum.GetName(typeof(Color), colorValue);
    }
}




// 假设有枚举值如下:
public enum DbProviderType
{
    SqlServer,
    Oracle
}
// 1、将枚举转换为字符串:
string strDbType = DbProviderType.SqlServer.ToString();
// 2、将字符串转换为枚举:
DbProviderType dbType = (DbProviderType)Enum.Parse(typeof(DbProviderType), strDbType, true);
