How to create a matrix with a new List of Color

Basically, what I want to do is this:

Dim colors1(100, 100) As New List(Of Color)

I need to create a matrix with the New List(Of Color).

I will explain better...

I want to read all the colors of the pixels of my image, and usualy i would do that by reading line by line. But that is not the case. I divide the image in 8x8 squares and i want create an matrix(whit position of square)and the List(Of Color)(whit the colors of that square) that says all the colors of each square. Infortunaly when i try do this Dim colors1(100,100) as List(Of Color)the program break.

Try this

        Dim colors1 As New List(Of List(Of Color))
        For i As Integer = 0 To 99
            Dim newColors As New List(Of Color)
            colors1.Add(newColors)
            For j As Integer = 0 To 99
                newColors.Add(New Color)
            Next
        Next​

Well, are you wanting to use an Array or a List for this?

If you want a fixed 100x100 matrix then you should use a 2D Array since arrays are fixed size.

If you're happy to use a fixed 100x100 2D Array, you can declare it like:

Dim colors1(100, 100) As Color

Set it like this:

colors1(5, 2) = Color.Aqua

And then use it like this:

' Sets the textbox background color to Aqua
TextBox1.BackColor = colors1(5, 2)

Does that achieve what you're trying to do? Or did you need the List for another reason?
