Assign values to 2D array

I need to assign values to 2D array but I can't find the right syntax. I tried this but is't wrong:

string[][] s2d = new string[][] {
  {"val1","val2"},
  {"val1bis","val2bis"}
};

Thanks

You are almost there, just change the convention and use [,]., [][] used to define Array of arrays (Jagged arrays). 

string[,] s2d = new string[,] {
  {"val1","val2"},
  {"val1bis","val2bis"}
};

If you want to enumerate on Multidimensional arrays you can do that but it is a flatten array. 

foreach(var s in s2d) 
{
    // logic
}

Just access the elements in traditional way (if want).

for(int i=0;i < s2d.GetLength(0);i++)
    for(int j=0;j < s2d .GetLength(1);j++)
        var val = s2d [i,j];

If you really want array of arrays so declare array of arrays

string[][] s2d = new string[][] {
  new string[] {"val1","val2"},
  new string[] {"val1bis","val2bis"}
};

If you truly want a 2d array

string[,] s2d = new string[2,2] { {"val1","val2"}, {"val1bis","val2bis"}};

string[][] gives you a possibility of a jagged array

You're using an incorrect syntax:

int[,] array2D = new int[,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };
