Question

How do I assign a value in a generics C# class?

public class GeneralWrapper<T>
{
    public GeneralWrapper()
    {
       Datas = new ?
    }

    public T Datas { get; set; }
}

I’m writing a generic wrapper class for a List objects (any object). So I can use this class like

GeneralWrapper<List<string>> _wrapper = new GeneralWrapper<List<string>>();
_wrapper.Datas.Add("hello")

but the Datas need to be automatically initialized in the constructor like

Datas = new Datas<t>();

it seems so that I don’t have to create new after I create the GeneralWrapper class.

Answer 1

public class GeneralWrapper<T> where T : class, new()
{
    public GeneralWrapper()
    {
       Datas = new T();
    }

    public T Datas { get; set; }
}
