C# populate string multidimensiona array inside a loop

Question

im trying to create a matrix and populate it with strings so i can manipulate it later, heres my code

using UnityEngine;
using System.Collections;

public class ScenarioMatrix : MonoBehaviour {

    public GFRectGrid _grid;
    public string[,] _scenarioArray;
    /*
    USAREMOS A SEGUINTE NOMECLATURA PARA O GRID
    E = GRID VAZIO TEM SOMENTE O CENARIO
    SP = Spawn Point, é onde o player começa
    EP = é onde o player termina
    L = Lajota é o caminho onde o player pode andar
    CG = color get, é onde o bloco pega uma cor
    CD = color drop é onde o bloco deixa a cor
    */
    private string[] _values = {"E","SP","EP","L","CG","CD" };

    // Use this for initialization
    void Start() {

        _scenarioArray = new string[(int)_grid.size.x, (int)_grid.size.z];

        //montamos o array
        for (int _largura = 1; _largura <= _grid.size.x; _largura++)
        {
            for (int _comprimento = 1; _comprimento <= _grid.size.z; _comprimento++)
            {
                string _valor = _values[Random.Range(0, _values.Length-1)];
                _scenarioArray[_largura, _comprimento] = _valor;
                //Debug.Log(_values[Random.Range(0, _values.Length)]);
            }

        }
        Debug.Log(_scenarioArray);
    }


    // Update is called once per frame
    void Update () {

    }
}

So far im getting the error IndexOutOfRangeException: Array index is out of range. ScenarioMatrix.Start () (at Assets/Game/Scripts/ScenarioMatrix.cs:30)

what can i be doing wrong in this code?

change for (int _largura = 0; _largura < _grid.size.x; _largura++) and for (int _comprimento = 1; _comprimento < _grid.size.z; _comprimento++) — SᴇM

replace _comprimento <= _grid.size.z with _comprimento < _grid.size.z

and

_largura <= _grid.size.x with _largura < _grid.size.x

Arrays index are 0 based (They start from 0, not 1)

worked the error is fixed how can i debug.log this matrix to see it?

just do //Debug.Log(_valor); in the inner for loop, Just after _scenarioArray[_largura, _comprimento] = _valor;

you should also start the loop with index 0. int _largura = 0 and int _comprimento = 0;
