Concat result of while loop

[bekoder]

Hi,
I'm using a while codition to iterate throw a collection by a certain step (BinSize). The result of each iteration is step.outputORFs. I want to concat or group the result of each iteration in the same variable so it can be used as an input for the next step.

 public class GenomeWorkflow : IWorkflow<GenomeData>
 {
  public void Build(IWorkflowBuilder<GenomeData> builder)
        {
            builder
                .StartWith<ReadFileStep>()
                .Then<ExtractORFsStep>()
                .Output(data => data.ORFS, step => step.ORFS)               
		.While(data => data.BinPosition < data.ORFS.Count)
		.Do(x => x
		        .StartWith<ClusterORFsStep>()
			.Input(step => step.inputORFs, data=> data.ORFS.GetRange(data.BinPosition, Math.Min(data.ORFS.Count - (data.BinPosition + data.BinSize) - 1, data.BinSize)))
			.Output(data => data.ClusteredORFS, step => step.outputORFs)
			.Then<IncrementBinStep>()
			.Input(step => step.BinPosition, data => data.BinPosition)
			.Input(step => step.BinSize, data => data.BinSize)
			.Output(data => data.BinPosition, step => step.BinPosition))
     	        .Then<LastStep>()
                //.Input(group output of all iterations : data.ClusteredORFS)
                .Then(context =>
                {						 
                    Console.WriteLine("Workflow comeplete");
                    return ExecutionResult.Next();
                });
        }

        public string Id => "Genome";
            
        public int Version => 1;
                 
    }

Any idea how to solve this?
Thanks.

Something like this?

public class GenomeWorkflow : IWorkflow<GenomeData>
 {
  public void Build(IWorkflowBuilder<GenomeData> builder)
        {
            builder
                .StartWith<ReadFileStep>()
                .Then<ExtractORFsStep>()
                    .Output(data => data.ORFS, step => step.ORFS)               
		.While(data => data.BinPosition < data.ORFS.Count)
		    .Do(x => x
		        .StartWith<ClusterORFsStep>()
			    .Input(step => step.inputORFs, data=> data.ORFS.GetRange(...)
			    .Output((step, data) => data.ClusteredORFS.AddRange(step.outputORFs))
			.Then<IncrementBinStep>()
    			    .Input(step => step.BinPosition, data => data.BinPosition)
			    .Input(step => step.BinSize, data => data.BinSize)
			    .Output(data => data.BinPosition, step => step.BinPosition))
     	        .Then<LastStep>()
                    .Input(step => step.inputORFs, data => data.ClusteredORFS)
                .Then(context =>
                {						 
                    Console.WriteLine("Workflow comeplete");
                    return ExecutionResult.Next();
                });
        }

        public string Id => "Genome";
            
        public int Version => 1;
                 
    }

Thanks Daniel. That works fine !
