SampleServiceClient wcfClient = new SampleServiceClient(new InstanceContext(this));
try
{
  using (OperationContextScope scope = new OperationContextScope(wcfClient.InnerChannel))
  {
    MessageHeader header
      = MessageHeader.CreateHeader(
      "Service-Bound-CustomHeader",
      "http://Microsoft.WCF.Documentation",
      "Custom Happy Value."
      );
    OperationContext.Current.OutgoingMessageHeaders.Add(header);

    // Making calls.
    Console.WriteLine("Enter the greeting to send: ");
    string greeting = Console.ReadLine();

    //Console.ReadLine();
    header = MessageHeader.CreateHeader(
        "Service-Bound-OneWayHeader",
        "http://Microsoft.WCF.Documentation",
        "Different Happy Value."
      );
    OperationContext.Current.OutgoingMessageHeaders.Add(header);

    // One-way
    wcfClient.Push(greeting);
    this.wait.WaitOne();

    // Done with service.
    wcfClient.Close();
    Console.WriteLine("Done!");
    Console.ReadLine();
  }
}
catch (TimeoutException timeProblem)
{
  Console.WriteLine("The service operation timed out. " + timeProblem.Message);
  Console.ReadLine();
  wcfClient.Abort();
}
catch (CommunicationException commProblem)
{
  Console.WriteLine("There was a communication problem. " + commProblem.Message);
  Console.ReadLine();
  wcfClient.Abort();
}

Remarks

Use this property to add reply headers that are sent by a service operation or request headers that are sent by a WCF client object.
