when we send long message as below method

if ((DataCodings)Enum.Parse(typeof(DataCodings), objSMS.messageType.ToString()) == DataCodings.Default)
_client.MapEncoding(DataCodings.Default, Encoding.Default);

//code for send multiple message asynchronously
byte[] b = Encoding.ASCII.GetBytes(ID);
ISubmitSmBuilder builder = SMS.ForSubmit()
.Text(objSMS.Message)
.From(SourcePrefix + objSMS.StrSenderId, (byte)SourceTon, (byte)SourceNPI)
.To(DestinationPrefix + objSMS.MobileNo, (byte)DestinationTon, (byte)DestinationNPI)
.Coding((DataCodings)Enum.Parse(typeof(DataCodings), objSMS.messageType.ToString()))
.AddParameter(OptionalTags.ReceiptedMessageId, b)
.DeliveryReceipt();

_client.SubmitAsync(builder);

we want use OnFullMessageReceived when we send long message but on client_evDeliverSm event data.Concatenation is null
so how can we get Concatenation message

I have the same problem, messageLong is 180 char
this is my code :

string ID = "1";
//code for send multiple message asynchronously
byte[] b = Encoding.ASCII.GetBytes(ID);
ISubmitSmBuilder builder = SMS.ForSubmit()
.Text(messageLong)
.From("mittente", AddressTON.International, AddressNPI.ISDN)
.To("3333333333", AddressTON.International, AddressNPI.ISDN)
.Coding(DataCodings.Default)
.AddParameter(OptionalTags.ReceiptedMessageId, b)
.DeliveryReceipt();

client.SubmitAsync(builder);

public static void client_evDeliverSm(object sender, DeliverSm data)
{
try
{
Concatenation concatenation = data.Concatenation;

// Receive incoming message and try to concatenate all parts
if (concatenation != null)
{

_composer.AddMessage(data);

string messageText = data.Client.GetMessageText(data);

Console.WriteLine("DeliverSm part received : "
+ " Sequence : " + data.Sequence
+ " SourceAddr : " + data.SourceAddr
+ " Concatenation ( " + concatenation + " )"
+ " Coding : " + data.DataCoding
+ " Text : " + messageText);


if (_composer.IsLastSegment(data))
{

string fullMessage = _composer.GetFullMessage(data);

Console.WriteLine("Full message text: " + fullMessage);
}

}
else
{ Console.WriteLine("single message "+ data.MessageText); }


}
catch (Exception ex)
{
data.Response.Status = CommandStatus.ESME_RX_T_APPN;

}
}

data.Concatenation in the event always is null.
Any answer?

what do you receive in evDeliverSm event? delivery receipt or message from mobile phone?
You should not expect concatenation parameter for delivery receipt.

Could you post here or send on support email the dump of this DeliverSm PDU?

Hi Alt,
This in my DeliverSm

{DeliverSm, Length: 174, Status: ESME_ROK, Sequence: 0, SourceAddr: 3333333333, DestAddr: mittente}
base {Inetlab.SMPP.PDU.SmppRequest<Inetlab.SMPP.PDU.DeliverSmResp>}: {DeliverSm, Length: 174, Status: ESME_ROK, Sequence: 0, SourceAddr: 3333333333, DestAddr: mittente}

Could you send me an example to send a long-text ?
In this case I set a Optional parameters OptionalTags.ReceiptedMessageId with .AddParameter(OptionalTags.ReceiptedMessageId, b) in SubmitSmBuilder How I can read it in DeliverSm TLV collections in empty.
Thanks

You don't need to send you own id with the message.
Remove following line from your code:

.AddParameter(OptionalTags.ReceiptedMessageId, b)

How to detect delivery receipt that correspond to submitted message you can read at
http://wiki.inetlab.com/doku.php/smpp/delivery_receipt

Thanks alt,
but data.Concatenation in DeliverSm data is null.

for Delivery Receipt it is always null
