将空值添加到枚举类

Question

下面是我的代码中可用的enum类，但是，我想为它添加一个空值。将空值添加到此类后，我收到错误。

public enum AgentLevel : int 
{

        [System.Runtime.Serialization.EnumMemberAttribute()]
        Location = 1,

        [System.Runtime.Serialization.EnumMemberAttribute(Value="Head Quarter")]
        HeadQuarter = 2,
}

Answer 1

如果您只需要初始化一个空字符串，那么您可以：

public enum AgentLevel : int {

        [System.Runtime.Serialization.EnumMemberAttribute(Value = "")]
        Location = 1,

        [System.Runtime.Serialization.EnumMemberAttribute(Value="Head Quarter")]
        HeadQuarter = 2,
    }
