Collection of generic plugins. How to?

Question

.NET

I have the following task:
there is a certain class

abstract class Plugin<T>
    {
        public abstract T Modify(T param);
    }

You need to write a class that stores a collection of plugins and is itself a plugin. The modify method must execute all collection plugins to param.
Please help with ideas on how to do this.

Answer 2

sealed class CompoundPlugin<T> : Plugin<T> {
  private readonly IReadOnlyList<Plugin<T>> plugins;

  public CompoundPlugin(IReadOnlyList<Plugin<T>> plugins) {
    Contract.Requires<ArgumentNullException>(plugins != null, "arg");
    Contract.Requires<ArgumentException>(plugins.Count > 0);

      this.plugins = plugins;
  }

  public override T Modify(T param) {
    return plugins.Aggregate(param, (arg1, plugin) => plugin.Modify(arg1));
  }
}
