This maybe a stupid question for which I apologies, but I couldn't

find a solutions so I'll ask.

I'm a newbie and I'm trying to do the following:

A have a base class called space that should accommodate all the

common operation over a dimensional object - vector, vertex or matrix.

public class Space

{

protected double [] data;

protected int columns;

protected int rows;

public Space( int _rows, int _columns )

{

rows = _rows;

columns = _columns;

data = new double[ rows * columns ];

}

public int Columns

{

get { return columns; }

}

public int Rows

{

get { return rows; }

}

public static Space operator +( Space rl, Space rr)

{

return new Space( rl.Rows, rl.Columns );

}

}

I also have a Vector class inherited from Space

public class Vector : Space

{

public Vector( ) : base( 1, 3 )

{

}

public static implicit operator Vector ( Space s )

{

return new Vector( s );

}

}

And I'm trying to use it as:

Vector v1 = new Vector( );

Vector v2 = new Vector( );

Vector v3 = v1 + v2;

And here I get the mentioned error CS0553.

How I should deal when I'm in need to implicitly convert one base

object to the inherited one?

Do you any of you have an idea how this could be solved?

thanks,
