Question

I need to implement a method which returns an object based on type like.

 public interface IBase
{ 
}
public class Base1 : IBase { }
public class Base2 : IBase { }
public class Base3 : IBase { }
public class MyClass
{
    public IBase GetObject<T>() where T:IBase
    {
        // should return the object based on type.
        return null;
    }

}

Do i need to maintain dictionary like inside the GetObject method?

            Dictionary<Type, IBase> test = new Dictionary<Type, IBase>();

Is there any better way for same?

[Edit]: – I dont want to create the object everytime. I need to keep it inside memory and when there is a call. I want to return the object from there. Apart from dictionary is there any other way?

Answer 1

public class MyClass {
    public IBase GetObject<T>() where T:IBase, new() // EDIT: Added new constraint 
    {
        // should return the object based on type.
        return new T();
    }

}
