Question regarding the base 'object' and boxing/unboxing. Since every type inherits from the base 'object' type, would it be something similar to this?

override

After typing this, it seems like object may even be using an interface, like so:

Based on this, if you inherit a class from a class that implements an interface, does the derived class also have to implement the interface or only if they explicitly state they will implement the interface?

If I understand this correctly, if I 'box' my int to an object {object o = (object)int} then I can only use the members of object, unless I cast (which unboxes or reboxes?)

If you've found the above a more human-readable format for learning beginning C#, please let me know. Note, this is again just an overview of the information in week 1. If this format receives enough interest, myself or another tutor will write similar overviews for the remaining chapters. Also, please let me know if the above is detailed enough, not detailed enough, etc...What do you want more of, what do you want less of?

This workshop is really about all of you. If you're not getting what you want, or what you expected from the workshop, please speak up so we know what level we need to cater to. If there's enough interest in this format, I'll begin by completing the information below.

WOW! Yesterday I read the chapters 1 and 2. Now, I just read ALL the ten pages. OMFG! I have to congratulate you guys, this workshop is really something!

About INDEXERS, I understood the concept but I didn't see any example and I am curious. Can anybody post a class that use an indexer?

Thanks.

public class Matrix{    // The indexer    public float this[int row, int col]    {        get        {            return _matrix[row, col];        }        set        {            _matrix[row, col] = value;        }    }    // Uses the indexer    public static Matrix operator +(Matrix a, Matrix b)    {        if ( a.IsSameSize( b ) )        {            float[,] m = new float[a.Height, a.Width];            for ( int i = 0; i != a.Height; ++i )            {                for ( int j = 0; j != a.Width; ++j )                {                    m[i, j] = a[i, j] + b[i, j];                }            }            return new Matrix( m );        }        else        {            throw new InvalidOperationException( "Matrices must be the same size" );        }    }    public Matrix(int rows, int cols)    {        _matrix = new float[rows, cols];    }    private Matrix(float[,] matrix)    {        _matrix = matrix;    }    public int Height    {        get        {            return _matrix.GetLength( 0 );        }    }    public int Width    {        get        {            return _matrix.GetLength( 1 );        }    }    public bool IsSameSize(Matrix other)    {        return this.Width == other.Width && this.Height == other.Height;    }    private float[,] _matrix;}

A very incomplete matrix class.

Ok, little backround on me, I've taken classes on C++ and Java... never taken C#, but I'm looking at snippets of code from the tutorials and I just want a bit of clarification.

Is C# a Hybrid of of sorts of Java and C++? there seems to be aspects of both languages in this one.
