Refer to one of many coroutines in Unity3D?

Is there a way to have a variable point to one of a number of coroutines in C# in Unity3D?

public class Example : MonoBehaviour
{
    ? something ?  crt;

    private IEnumerator CoroutineA()
    {
    }

    private IEnumerator CoroutineB()
    {
    }

    void Start()
    {
        crt = CoroutineA;
        StartCoroutine(crt);
    }
}

Answer

The type that you are looking for is a delegate. Delegates are similar to function pointers, and are not specific to Unity3D.

public class Example : MonoBehaviour
{
    private delegate IEnumerator CoroutineDelegate();

    private IEnumerator CoroutineA()
    {
    }

    private IEnumerator CoroutineB()
    {
    }

    public void Start()
    {
        CoroutineDelegate crt = CoroutineA;
        StartCoroutine(crt());
    }
}
