팩토리 패턴과 함께 이런식으로 쓸 수 있다.

public abstract class SomeStrategy
{
	public abstract void CreateSomeThing(ref SomeObject someObject);
}

public class SomeStrategyA : SomeStrategy
{
	public SomeStrategyA() { /* Constructor */ }

	public override void CreateSomeThing(ref SomeObject someObject)
	{
		someObject = new SomeObjectA();
	}
}

public class SomeClassB : SomeStrategy
{
	private SomeVariable someVariable; // Only for SomeClassB

	public SomeClassB(int a, int b)
	{
		someVariable = new SomeVariable();
	}

	public override void CreateSomeThing(ref SomeObject someObject)
	{
		someObject = new SomeObjectB();
	}
}

public class SomeFactory
{
	public SomeStrategy CreateSomeStrategy() => someEnum switch
	{
		SomeEnum.A => new SomeStrategyA(),
		SomeEnum.B => new SomeStrategyB(1, 2),
		_ => throw new ArgumentOutOfRangeException(nameof(someEnum), someEnum, null)
	};
}
