Question

In this example:

abstract class MyList<T>: List<T>
{
    public T Find(int? id)
    {
        foreach(T obj in this)
        {
            if(Compare(id, obj))
                return obj;
        }
        return default(T);
    }

    protected abstract bool Compare(int? id, T obj);
}

I get the error

foreach statement cannot operate on variables of type LearningScriptSharp.MyList<T> because LearningScriptSharp.MyList<T> does not contain a public definition for GetEnumerator.

How can I enumerate this list?

Answer 1

Firstly, apparently one can’t define a generic type in Script#… compiler fails, without error messages.

So I’m going to go with this, unless anyone has a better suggestion:

abstract class MyList
{
    private List<Object> innerList = new List<Object>();

    public Object Find(int? id)
    {
        foreach(Object obj in innerList)
        {
            if(Compare(id, obj))
                return obj;
        }
        return default(Object);
    }

    protected abstract bool Compare(int? id, Object obj);
}
