Set binding and address of WCF service using c# code

We can set binding type and enpoint address by code.
We have already add the service reference to the project and try below code

 GatewayProxy.GatewayClient gatewayProxy;
            BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
            EndpointAddress endPoint = new EndpointAddress("http:localhost:11105/Gateway.svc?wsdl");
            basicHttpBinding.MaxBufferSize =65536;
            basicHttpBinding.MaxReceivedMessageSize = 65536
            XmlDictionaryReaderQuotas readerQuotas = new XmlDictionaryReaderQuotas();
            readerQuotas.MaxStringContentLength = 65536;
            readerQuotas.MaxArrayLength =65536;
            basicHttpBinding.ReaderQuotas = readerQuotas;
            using (this.gatewayProxy = new GatewayProxy.GatewayClient(basicHttpBinding, endPoint))
            {
              //write a code to call service function
            }
