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();
string enumStringTwo = Enum.GetName(typeof(Color), color);

//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);
