How do you loop through a multidimensional array?

Question

foreach (String s in arrayOfMessages)
{
    System.Console.WriteLine(s);
}

string[,] arrayOfMessages is being passed in as a parameter

Answer 1

Simply use two nested for loops. To get the sizes of the dimensions, you can use GetLength():

for (int i = 0; i < arrayOfMessages.GetLength(0); i++)
{
    for (int j = 0; j < arrayOfMessages.GetLength(1); j++)
    {
        string s = arrayOfMessages[i, j];
        Console.WriteLine(s);
    }
}

This assumes you actually have string[,]. In .Net it's also possible to have multidimensional arrays that aren't indexed from 0. In that case, they have to be represented as Array in C# and you would need to use GetLowerBound() and GetUpperBound() the get the bounds for each dimension.
