如何设置submit sm让客户端使用它在jamaa smpp中的属性来发送消息？

SmppClient client = new SmppClient();
client.Connect("smppserver.com", 2775);
client.Bind("username", "password", ConnectionMode.Transceiver);

SubmitSm submitSm = new SubmitSm();
submitSm.SourceAddress = "sender";
submitSm.DestinationAddress = "recipient";
submitSm.ShortMessage = "Hello, World!";
submitSm.DataCoding = DataCodings.Default;
submitSm.RegisteredDelivery = true;
submitSm.ScheduleDeliveryTime = DateTime.Now.AddMinutes(10);

SmppSubmitResult submitResult = client.Submit(submitSm);
if (submitResult.Success)
{
    Console.WriteLine("Message sent successfully! Message ID: " + submitResult.MessageId);
}
else
{
    Console.WriteLine("Failed to send message: " + submitResult.ErrorCode);
}
