Add config editor To create an interactive command-line experience where users can select processors from a list and then add their selection to the configuration, you can utilize Updated ImplementationThis implementation will present the user with a list of processors, allow them to select one or more, and then update the configuration file accordingly. using System;

This is a new example that puts
ProcessorContainer
,IProcessor
implementations,ProcessorLoaderService
,Engine
, and theProgram.cs
setup. This example demonstrates how to dynamically load and execute processors using configuration and dependency injection in .NET.Processors.cs
appsettings.json
Program.cs
Explanation and Flow
Processor Classes (
ProcessorA
andProcessorB
): These classes implement theIProcessor
interface and accept their settings viaIOptions<T>
. They each have anExecuteAsync
method that prints out a message.ProcessorContainer: A container that holds a list of
IProcessor
instances.ProcessorLoaderService: This service loads processor configurations from
appsettings.json
, merges them with defaults (and environment variables), and creates instances of the processors using DI.Engine: The
Engine
class iterates over the processors inProcessorContainer
and runs theirExecuteAsync
methods.Program.cs:
ProcessorContainer
.Engine
, which processes each processor.Running the Application
When you run the application, the following occurs:
Engine
executes each processor in the order specified in the configuration.ProcessorA
andProcessorB
have been executed with their respective settings.This structure provides a flexible and maintainable approach to dynamically configuring and executing processors in a .NET application.
