BrokeredMessage message=new BorkeredMessage("My message to queue123");
qclient.send(message);

Receive Message :
================
BrokeredMessage message=null;
String strcon = ConfigurationManager.Appsettings["Microsoft.ServiceBus.ConnectionString"].tostring();

QueueClient qclint = QueueClient.CreateFromConnectionString(strcon,"TestQueue123");
 message= qclint.Receive(TimeSpan.FromSeconds(5));
if(message!=null)
{
message.complete();
}

qclient.close();
