enum.ToString返回错误的值？ [英] enum.ToString return wrong value?

问题描述

我有一个简单的枚举：

public enum MyEnum
        {
            [Description("Zero")]
            Zero,
            [Description("A positive number")]
            Positive,
            [Description("Any integer")]
            AnyInteger,
            [Description("A negative number")]
            Negative,
            [Description("Reserved number")]
            Reserved =2
           }

但是，运行以下代码：

MyEnum temp = MyEnum.AnyInteger;

MyEnum temp=MyEnum.AnyInteger;

string en = temp.ToString（）;

string en=temp.ToString();

将en字符串设置为Reserved。

sets the en string to Reserved.

为什么会这样？

有没有其他方法可以将字符串设置为使用的枚举字符串（在这种情况下为AnyInteger）？

Is there is some other way to set the string to the used enum string (in this case AnyInteger)?

推荐答案

当定义枚举时，第一个值以 0 开始，并且从那里开始，除非你定义其他明智的，所以在你的案例是：

when defining an enum the first value start with 0 and it going up from there unless you define other wise, so in your case it's:

public enum MyEnum
        {
            [Description("Zero")]
            Zero, //0
            [Description("A positive number")]
            Positive, //1
            [Description("Any integer")]
            AnyInteger, //2
            [Description("A negative number")]
            Negative, //3
            [Description("Reserved number")]
            Reserved = 2 // it's 2 again
           }

您可以在枚举中定义相同的值两次（或更多）。 ToString 找到一个具有相同值的名称：

you can define the same value twice (or more) in a enum. the ToString find a name with the same value:

MyEnum temp=MyEnum.AnyInteger; //temp = 2

string en=temp.ToString(); // return the name of the first name with value 2.

如果您坚持保留有价值2，把他放在正确的地方。否则删除 = 2

if you insist that "Reserved" should have the value 2, put him in the right place of order. otherwise remove the =2
