改变枚举的数量是一个突破性的变化吗？

Question

请考虑以下代码:

public enum SomeCode
{
     NIF = 0
    ,NIE = 1
    ,CIF = 2
    ,PAS = 3
    ,NIN = 4
    ,SSN = 5
    ,OTH = 5
    ,UKN = 6
}

会改变OTH = 5成OTH = 7一个突破性的变化吗？

编辑:我从不存储int值,只存储枚举的文本表示.它可能在其他DLL中使用,但会使用相同的存储.

It is a breaking change, as you are changing a public API.

Libraries/applications that were built with the old value will still hold the old value and use it. You will need to recompile them all.

From MSDN - enum (C# Reference):

与任何常量一样,对枚举的各个值的所有引用在编译时都将转换为数字文字.这可能会产生潜在的版本控制问题,如常量(C#编程指南)中所述.
