请教一个枚举类型的问题！

[zklvy]

有个问题想问你一下：
我定义了一个枚举类型字段，
public enum OnOffLine:byte
{
允许脱机 = 0,
不允许脱机 = 1
}
我想这样用：从数据库里提出一个字段的值是：0，我就转换成相应：允许脱机
枚举类型我不熟悉，大家给个方法！

请教！

// val = ...
if(val == 0)
{
return OnOffLine.允许脱机;
}
...

下面的代码示例说明 Enum 的用法：

using System;

public class EnumTest {
enum Days { Saturday, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday };
enum BoilingPoints { Celcius = 100, Fahrenheit = 212 };
[FlagsAttribute]
enum Colors { Red = 1, Green = 2, Blue = 4, Yellow = 8 };

public static void Main() {

Type weekdays = typeof(Days);
Type boiling = typeof(BoilingPoints);

Console.WriteLine("The days of the week, and their corresponding values in the Days Enum are:");

foreach ( string s in Enum.GetNames(weekdays) )
Console.WriteLine( "{0,-11}= {1}", s, Enum.Format( weekdays, Enum.Parse(weekdays, s), "d"));

Console.WriteLine();
Console.WriteLine("Enums can also be created which have values that represent some meaningful amount.");
Console.WriteLine("The BoilingPoints Enum defines the following items, and corresponding values:");

foreach ( string s in Enum.GetNames(boiling) )
Console.WriteLine( "{0,-11}= {1}", s, Enum.Format(boiling, Enum.Parse(boiling, s), "d"));

Colors myColors = Colors.Red | Colors.Blue | Colors.Yellow;
Console.WriteLine();
Console.WriteLine("myColors holds a combination of colors. Namely: {0}", myColors);
}
}

jiezhi(風依舊) ：
你试过你的方法？
return OnOffLine.允许脱机返回的是0吧？
我想返回的是允许脱机

[zedan]

可以这样定义啊：
public enum OnOffLine:byte
{
0=允许脱机 ,
1=不允许脱机
}
也没细看枚举，不知可否，试试吧

zedan(kk) ：
你真的没看过枚举
这样是不可以的
