Question

I have simple code witch works ok:

public class Example
{

    private List<SomeClass> _list = new List<SomeClass>();

    public void Add(SomeClass _b) {
        _list.Add(_b);
    }

}

it possible to add SomeClass to _list something like this? (without specifying argument)?

public void Add<T>() where T : SomeClass
{

}

Answer 1

Assuming that SomeClass has a default constructor, you can:

public void Add<T>() where T : SomeClass, new()
{
    _list.Add(new T());
}

If SomeClass does not have a default constructor then you won’t be able to write new T() and you will need to find another way of getting a T object.
