See below the plain readable code for cloning a generic collection in C#:

namespace Org.Project.Common

{
  using System;
  using System.Collections.Generic;
   public static class CloneableExtension
   {
     public static IList<T> Clone<T>(this IList<T> list) where T : ICloneable
     {

        IList<T> clonedList;

        clonedList = new List<T>();
        foreach (T cloneable in list)
        {
          object clonedObj = cloneable.Clone();
          clonedList.Add((T)clonedObj);
        }
        return clonedList;

     }
  }
  

}

The method extends all collections that implements IList but returns instance of List always.
The objects of type T that the list consists of should implement ICloneable interface.

Here is another stylish implementation using LINQ:

namespace Org.Project.Common{
  using System;
  using System.Collections.Generic;
  using System.Linq;
  public static class CloneableExtension
  {
   public static IList<T> Clone<T>(this IList<T> list) where T : ICloneable
   {     return list.Select(item => (T)item.Clone()).ToList();    }
  }
}
