C# Exchange 2010推送订阅WCF SOAP

我正在尝试使用Exchange 2010的PushSubscription功能。到目前为止，我已经获得了在Exchange 2010上安装推送的代码：

ExchangeService esService = new ExchangeService();
esService.Credentials = new WebCredentials("user", "pass", "domain");
esService.Url = new Uri("https://exchange-box-2010/ews/exchange.asmx");

PushSubscription ps = esService.SubscribeToPushNotificationsOnAllFolders(new Uri("http://192.168.1.102:8080/FinWorkFlow"), 1, null, EventType.NewMail, EventType.Copied);

我还有一个WCF服务，它在运行时使用tcp跟踪实用程序从8080重定向到80。跟踪表明Exchange向发送了请求，并且从我的WCF服务发送了良好的响应。但是，SendNotification方法的SendNotificationResponseType参数始终为空：

SendNotificationResultType INotificationServiceBinding.SendNotification(SendNotificationResponseType request)
        {
            if(request != null && request.ResponseMessages != null)
            {
                foreach(ResponseMessageType messsage in request.ResponseMessages.Items)
                {
                    if(messsage.ResponseCode != ResponseCodeType.NoError)
                    {
                        return CreateNotificationResult(SubscriptionStatusType.Unsubscribe);
                    }

                    SendNotificationResponseMessageType mtNotificationMessage = (SendNotificationResponseMessageType)messsage;
                    NotificationType ntNotification = mtNotificationMessage.Notification;
                    string strSubscriptionId = ntNotification.SubscriptionId;

                    for(int i = 0; i < ntNotification.Items.Length; i++)
                    {
                        if(ntNotification.ItemsElementName[i].ToString() == "NewMailEvent")
                        {
                            BaseObjectChangedEventType bocet = (BaseObjectChangedEventType)ntNotification.Items[i];
                        }
                    }
                }
            }

            return CreateNotificationResult(SubscriptionStatusType.OK);
        }

SendNotificationResultType INotificationServiceBinding.SendNotification（SendNotificationResponseType请求）
{
if（request！=null&&request.ResponseMessages！=null）
{
foreach（请求中的ResponseMessageType Message.ResponseMessages.Items）
{
if（Message.ResponseCode！=ResponseCodeType.NoError）
{
返回CreateNotificationResult（SubscriptionStatusType.Unsubscribe）；
}
SendNotificationResponseMessageType mtNotificationMessage=（SendNotificationResponseMessageType）消息；
NotificationType ntNotification=mtNotificationMessage.Notification；
字符串strSubscriptionId=ntNotification.SubscriptionId；
对于（int i=0；i

有人能解释一下为什么SOAP请求的主体没有被提取并放入SendNotificationResponseType变量中吗？

终于找到了答案

事实证明，我使用了wsdl工具来构建接口——应该使用svcutil。这构建了一个具有正确方法属性的接口。

此机制是否支持新邮件到达邮箱时的通知？我是否可以注册新邮件事件-一次，并在邮件到达设备时立即接收邮件，而无需每隔几分钟轮询并向服务器发送请求。。？我希望能够尽快处理新邮件。
