You just declared a jagged array  Such kind of arrays can have different sizes for all dimensions  For example   string     jaggedStrings      new string     x   y   z    new string     x   y    new string     x        In your case you need regular array  See answers above  More about jagged arrays

string    Tablero   new string 3 3     You can also instantiate it in the same line with array initializer syntax as follows   string    Tablero   new string 3  3     a   b   c                                            d   e   f                                             g   h   i

There are 2 types of multidimensional arrays in C   called Multidimensional and Jagged    For multidimensional you can by   string    multi   new string 3  3    For jagged array you have to write a bit more code   string     jagged   new string 3                 for  int i   0  i  lt  jagged Length  i                                  jagged i    new string 3                   In short jagged array is both faster and has intuitive syntax  For more information see  this Stackoverflow question

A 3x3  multidimensional  array can also be initialized  you have already declared it  like this   string    Tablero                                 a    b    c                                d    e    f                                 g    h    i

You probably want this   string    Tablero   new string 3 3     This will create you a matrix-like array where all rows have the same length   The array in your sample is a so-called jagged array  i e  an array of arrays where the elements can be of different size  A jagged array would have to be created in a different way   string     Tablero   new string 3     for  int i   0  i  lt  Tablero GetLength 0   i          Tablero i    new string 3       You can also use initializers to fill the array elements with data   string    Tablero   new string            1 1   1 2    1 3          2 1   2 2    2 3          3 1    3 2    3 3        And in case of a jagged array   string     Tablero   new string           new string     1 1   1 2    1 3        new string     2 1   2 2    2 3        new string     3 1    3 2    3 3

string     is not a two-dimensional array  it s an array of arrays  a jagged array   That s something different   To declare a two-dimensional array  use this syntax   string    tablero   new string 3  3     If you really want a jagged array  you need to initialize it like this   string     tablero   new string       new string 3                                          new string 3                                          new string 3

I assume you re looking for this           string    Tablero   new string 3 3     The syntax for a jagged array is           string     Tablero   new string 3             for  int ix   0  ix  lt  3    ix                Tablero ix    new string 3
