Question

林试图写入一个交换转运剂测试是否主题行是空的，如果它比它插入一个默认主题行。每当我编译，安装和启用这个DLL的服务器将不再将电子邮件路由...

using System.Diagnostics;
using Microsoft.Exchange.Data.Transport;
using Microsoft.Exchange.Data.Transport.Email;
using Microsoft.Exchange.Data.Transport.Smtp;
using Microsoft.Exchange.Data.Transport.Routing;
using Microsoft.Exchange.Data.Common;

namespace ExchangeTransportAgent
{
    public class RoutingFactory : RoutingAgentFactory
    {

        public override RoutingAgent CreateAgent(SmtpServer server)
        {
            RoutingAgent myAgent = new sRoutingAgent();
            return myAgent;
        }
    }
}




class sRoutingAgent : RoutingAgent
{

    public sRoutingAgent()
    {
        //subscribe to different events
        base.OnSubmittedMessage += new SubmittedMessageEventHandler(SRoutingAgent_OnSubmittedMessage);
    }

    void SRoutingAgent_OnSubmittedMessage(SubmittedMessageEventSource source, QueuedMessageEventArgs e)
    {
        if (e.MailItem.Message.Subject == string.Empty)
        {
            try
            {
                e.MailItem.Message.Subject = "Kranichs Jewelers";


                EventLog.WriteEntry("MY Exchange Routing Agent", "MY ROUTING AGENT CHANGED THE SUBJECT",
                EventLogEntryType.Information, 1337);
            }
            catch (Exception except)
            {
                EventLog.WriteEntry("MY Exchange Routing Agent", except.Message,
                    EventLogEntryType.Error);
            }
        }
    }

}

没有人知道为什么这可能无法正常工作？

感谢

“EventLog.WriteEntry” 也许抛出异常。我有同样的问题，当删除“EventLog.WriteEntry”一切都OK。现在我不知道为什么。
