[DataContract]
public class OrderSyncData : ISync
{
 
    public OrderSyncData(Order o)
    {
        this.CurrentOrderStatus = o.DriverStatus;
        this.StatusDescription = o.StatusDescription;
        SyncTimestamp = o.SyncTimestamp; ????
    }
    [DataMember]
    public string CurrentOrderStatus { get; set; }
    [DataMember]
    public string StatusDescription { get; set; }
    [DataMember]// I don't think I need these any more
    public bool IsCanceled { get; set; }
    [DataMember]
    public bool IsResolved { get; set; }
    [DataMember]
    public bool IsPendingResponse { get; set; }
 
    DateTime ISync.SyncTimestamp { get; set; }
}

如何设置ISync.SyncTimestamp的值？我试着施放“这个”.但它不起作用
