Cannot declare generic list as member of parent class

Unity Engine

Created a script like the following to define a class called ScrollViewController, and I want to inherit it in multiple classes. At this time, I prepared a virtual property named DataList with a generic type list as its element, and I want to allow specifying the data type in the child classes.

ScrollViewController.cs

abstract class ScrollViewController<T> : MonoBehaviour
{
    protected virtual List<T> DataList
    {
        get { return dataList; }
        set { dataList = value; }
    }
    private List<T> dataList;
}

EngineerScrollViewController.cs

class EngineerScrollViewController : ScrollViewController<Engineer>
{
    private List<Engineer> dataList = new List<Engineer>();
    protected override List<Engineer> DataList
    {
        get { return dataList; }
        set { dataList = value; }
    }
}

However, I encountered an error message like below. Do you have any solutions to resolve this?

Assets/Scripts/ScrollViewController.cs(51,24): error CS0029: Cannot implicitly convert type 'System.Collections.Generic.List<Engineer>' to 'System.Collections.Generic.List<T>'

The article I referred to:

The property here seems completely unnecessary.

Just have a protected member:

public abstract class ScrollViewController<T> : MonoBehaviour
{
    protected List<T> dataList = new List<T>();
}

Solved, thank a lot!
