从 Serializationinfo 商店反序列化枚举？

Question

我有一个名为UnitsManager 的课程。在这个类中有一个枚举：

public enum TimeUnit
{
    Seconds,
    Milliseconds,
    Minutes,
    Hours,
    Days,
    Months,
    Years
}

这个枚举用在另一个名为Process 的类中。它有一个属性：

    private TimeUnit cycleTimeUnit = TimeUnit.Seconds; 
    [XmlAttribute("CycleTimeUnit")]
    public TimeUnit CycleTimeUnit
    {
        get { return this.cycleTimeUnit; }
        set { this.cycleTimeUnit = value; }
    }

我正在尝试序列化和反序列化 Process 类。我已经在 Process 类上实现了 ISerializable

    public override void GetObjectData(SerializationInfo info, StreamingContext context)
    {
        base.GetObjectData(info, context);

        info.AddValue("CycleTime", CycleTime);
        info.AddValue("CycleTimeUnit", CycleTimeUnit);
    }

我的问题在于反序列化

    private Process(SerializationInfo info, StreamingContext context)
    {
        CycleTime = info.GetDouble("CycleTime");
        CycleTimeUnit = info.????("CycleTimeUnit"); // <--- ???
    }

如何将其转换为 CycleTimeUnit 类型？

Answer 1

试试这个：

private Process(SerializationInfo info, StreamingContext context)
{
    CycleTime = info.GetDouble("CycleTime");
    CycleTimeUnit = (TimeUnit) info.GetValue("CycleTimeUnit", typeof(TimeUnit)); 
}
