C# Calling base constructor

I've Google'd "calling base constructor", and I'm not getting the answers I need.

Here's the constructor I have;

public class defaultObject
{
    Vector2 position;
    float rotation;
    Texture2D texture;

    public defaultObject(Vector2 nPos, float nRotation, Texture2D nTexture)
    {
        position = nPos;
        rotation = nRotation;
        texture = nTexture;
    }
}

Now I have that in place, I want to inherit the constructor and all its workings. This is what I'd expect to do;

public class Block : defaultObject
{
    // variables inherited from defaultObject
    public Block : defaultObject; //calls defaultObject constructor
}

Why can't I do that?

Use : base():

public class Block : defaultObject
{
    // variables inherited from defaultObject
    public Block ()
        : base()
    {}
}

or with parameters:

public class Block : defaultObject
{
    // variables inherited from defaultObject
    public Block (Vector2 nPos, float nRotation, Texture2D nTexture)
        : base(nPos, nRotation, nTexture)
    {}
}

you have multiple problems in your code. It should be like this

public Block(Vector2 nPos, float nRotation, Texture2D nTexture) : base(nPos,nRotation,nTexture) // see the way params are passed to the base constructor
{}

To call the base class's constructor:

public class Block : defaultObject
{
    // variables inherited from defaultObject
    public Block(npos, rotation, texture) : base(npos, rotation, texture); //calls defaultObject constructor
}

To override the update method, you must declare it virtual in the base class:

public virtual void update() { .. }

Why is it hiding an inherited member?

Because I bet the method in the base class is not marked virtual.

I see that you removed that part of the question. Well, I've answered it anyway now...
