What would be the right modifier?

Question

I have the following class with some methods and I would like to use this as a base class of another class.

public class BaseClass 
{
    public string DoWork(string str)
    {
        // some codes...
    }

    // other methods...
}

I don't want this class to be instantiated, but the derived class should still use the original implementation of the methods of its base class.

Is it possible? What should be my modifier?

Answer 1

Since you don't want this class to be instantiated, make it an abstract class. You can still have implementation on the class.

• abstract

snippet,

public abstract class BaseClass 
{
    public virtual string DoWork(string str)
    {
        // can have implementation here
        // and classes that inherits can overide this method because of virtual.
    }

    // other methods...
}
