Question

我有一个序列化TimezoneInfo的问题，因为它没有无参数构造函数。我试图通过做这里建议的事情来解决它

这是我的请求对象的样子

[MessageContract(WrapperNamespace = ServiceConstants.ContractNameSpaceMessageContract)]
public class GetTransactionsRequest
{
    [MessageHeader(Namespace = ServiceConstants.ContractNameSapceMessageHeader)]
    public DateTime EndDate { get; set; }

    [MessageHeader(Namespace = ServiceConstants.ContractNameSpaceMessageContract)]
    public DateTime StartDate { get; set; }

    [MessageHeader(Namespace = ServiceConstants.ContractNameSpaceMessageContract)]
    public string TimeZoneInfo
    {
        get { return tzInfo.ToSerializedString(); }
        set { tzInfo = System.TimeZoneInfo.FromSerializedString(value); }
    }

    private TimeZoneInfo tzInfo;
    public TimeZoneInfo TZInfo
    {
        get { return tzInfo; }
        internal set { tzInfo = value; }
    }

}

我有以下合约界面

[ServiceKnownType(typeof(System.TimeZoneInfo))]
[ServiceKnownType(typeof(System.TimeZoneInfo.AdjustmentRule))]
[ServiceKnownType(typeof(System.TimeZoneInfo.AdjustmentRule[]))]
[ServiceKnownType(typeof(System.TimeZoneInfo.TransitionTime))]
[ServiceKnownType(typeof(System.DayOfWeek))]

[ServiceContract(Name = "TransactionLobService", Namespace = ServiceConstants.ContractNameSpace)]
public interface ITransactionLobService
{

    [OperationContract]
    [WebGet(UriTemplate = "/GetTransactions")]
    [FaultContract(typeof(ExpenseAutomationFault))]
    GetTransactionsResponse GetTransactions(GetTransactionsRequest request);
}

我正在使用这样的服务

    Dim client As TransactionLobService = New TransactionLobServiceClient()

    Dim getTransactionsRequest As New TransactionsLOBService.GetTransactionsRequest() With {
        .TimeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById("AUS Eastern Standard Time").ToSerializedString(),
        .StartDate = Convert.ToDateTime("2017-03-27 00:00:00"),
        .EndDate = DateTime.Now
    }

    Dim response = client.GetTransactions(getTransactionsRequest)

我仍然收到以下错误： -

System.InvalidOperationException：出现了反映类型＆＃39; GetTransactionsRequest＆＃39;的错误。 ---＆GT; System.InvalidOperationException：无法序列化成员＆＃39; GetTransactionsRequest.TZInfo＆＃39;类型＆＃39; System.TimeZoneInfo＆＃39;，有关更多详细信息，请参阅内部异常。 ---＆GT; System.InvalidOperationException：System.TimeZoneInfo无法序列化，因为它没有无参数构造函数。

非常感谢任何帮助
