How to invoke/call custom cmdlet from another custom cmdlet in powershell

For example you have a requirement where you are writing custom cmdlet cmdLET1 which in turn needs to invoke cmdLET2.In such a scenario the challenge remains how to pass the parameters to the second cmdlet being invoked and also how exactly to invoke it.

Shown below is the sample code which shows how do we achieve such a scnerio

     PowerShell pShell = PowerShell.Create();

            Runspace runSpace = RunspaceFactory.CreateRunspace();

            runSpace.Open();

            Pipeline pipeline = Runspace.DefaultRunspace.CreateNestedPipeline();

            Command cmd = new Command("Add- cmdLET2");

            CommandParameter cmdPara1 = new CommandParameter("parameter1", value1);

            cmd.Parameters.Add(cmdPara1);

            CommandParameter cmdPara2 = new CommandParameter("parameter2", value2);

            cmd.Parameters.Add(cmdPara2);

            pipeline.Commands.Add(cmd);

            pShell.Commands.AddCommand("import-module").AddParameter("Name", "Add- cmdLET2");

            pipeline.Invoke();

The above code when called from cmdLET1 will invoke cmdLET2 with values passed in the CommandParameter’s
