### What is two dimensional declaration for string array?

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. There are 2 types of multidimensional arrays in C#, called Multidimensional and Jagged .

What is 2D and 3D array?

A two-dimensional (2D) array is an array of arrays. A three-dimensional (3D) array is an array of arrays of arrays. In C programming an array can have two, three, or even ten or more dimensions. The maximum dimensions a C program can have depends on which compiler is being used.

What are the disadvantages of a multidimensional array?
