Updating the global environment by using a .NETCompute node

The Global Environment can be altered at any point during the message flow; therefore you do not make a copy of it to alter. The following C# code shows how to change the global environment in a .NETCompute node:

        public override void Evaluate(NBMessageAssembly inputAssembly)
        {
            NBOutputTerminal outTerminal = OutputTerminal("Out");
            NBMessage inputMessage = inputAssembly.Message;
            // Create a new empty message, ensuring it is disposed after use
            using (NBMessage outputMessage = new NBMessage())
            {
                NBMessageAssembly outAssembly = new NBMessageAssembly(inputAssembly, outputMessage);
                NBElement inputRoot = inputMessage.RootElement;
                NBElement outputRoot = outputMessage.RootElement;

                // Optionally copy message headers, remove if not needed
                CopyMessageHeaders(inputRoot, outputRoot);

                #region UserCode
                // Add user code in this region to create a new output message
                NBMessage env = outAssembly.Environment;
                env.RootElement.CreateFirstChild(null, "Status", "Success");                               
                #endregion UserCode

                // Change the following if not propagating message to the 'Out' terminal
                outTerminal.Propagate(outAssembly);
            }
        }
