How do access data in a 2-dimensional array?

I have a 2-dimensional array that I built. For some reason, I can't remember how to extract the data from it using a For Loop. Here is what I have, which doesn't make sense to me because it appears that I'm doing the same thing twice.

    Dim strData As String = ""

    For x As Integer = 0 to arrLoadTest.Length - 1
        For y As Integer = 0 to arrLoadTest.Length - 1
            strData = arrLoadTest(x, y)
        Next
    Next
0

That is correct. While the first loop x goes from o to the end of the first index the second loop y is going through the second index in like manner. So that it accesses the array as follows:

arrLoadTest(0,0),  arrLoadTest(0,1), ..., arrLoadTest(0,n)
arrLoadTest(1,0),  arrLoadTest(1,1), ..., arrLoadTest(1,n)
...
arrLoadTest(m,0),  arrLoadTest(m,1), ..., arrLoadTest(m,n)
0

Ok, after I thought it through it made sense. The array was based off of a DataGridView (the number of rows and columns) so I just stored those values into variables and used those variables as the indexes.
