Can I somehow force a derived class to always call the overridden methods base?

public class BaseClass
{
    public virtual void Update()
    {
        if(condition)
        {
            throw new Exception("..."); // Prevent derived method to be called
        }
    }
}

And then in a derived class :

public override void Update()
{
    base.Update(); // Forced call

    // Do any work
}

I've searched and found a suggestion to use a non-virtual Update() but also a protected virtual UpdateEx(). It just doesn't feel very neat, isn't there any better way?

I hope you get the question and I am sorry for any bad English.
