Creating an Array of Arrays of PictureBox type

Question

This is how I am trying to implement my PictureBox arrays:

    PictureBox[] column0 = new PictureBox[6];
    PictureBox[] column1 = new PictureBox[6];
    PictureBox[] column2 = new PictureBox[6];
    PictureBox[] column3 = new PictureBox[6];
    PictureBox[] column4 = new PictureBox[6];
    PictureBox[] column5 = new PictureBox[6];
    PictureBox[] column6 = new PictureBox[6];

    PictureBox[][] columns = 
            new PictureBox[][] 
            { column0, column1, column2, column3, column4, column5, column6 };

When I try to make the array of arrays, I get this error:

A field initializer cannot reference the non-static field method, or property 'Connect_Four_Server.Server.column0'

and same errors for column1, column2, etc.

How does one declaring an array of arrays correctly in this situation?

The problem is not creating the array of arrays, maybe you have some server connection problems... — Tomas Ramirez Sarduy

I get this error before I even compile. I get the red line beneath the column0, column1, etc. doing this offline right now, ignore the name server for now — AGleasonTU

There's nothing wrong with the above declaration per se, but you can't use it like that if you are declaring fields in a class. As the error states, a field initializer (in your case columns) can't reference other non static fields (in your case column0, column1...).

There are 2 approaches you can take:

Either don't declare intermediate fields and do it all in one piece (best unless you actually need direct references to columnX):

PictureBox[][] columns =
        new PictureBox[][] 
        { 
            new PictureBox[6], 
            new PictureBox[6], 
            new PictureBox[6], 
            new PictureBox[6], 
            new PictureBox[6], 
            new PictureBox[6], 
            new PictureBox[6] 
        };

Or put the initialization of columns into the constructor:

PictureBox[] column0 = new PictureBox[6];
PictureBox[] column1 = new PictureBox[6];
PictureBox[] column2 = new PictureBox[6];
PictureBox[] column3 = new PictureBox[6];
PictureBox[] column4 = new PictureBox[6];
PictureBox[] column5 = new PictureBox[6];
PictureBox[] column6 = new PictureBox[6];

PictureBox[][] columns;

public Server()
{
    columns = new PictureBox[][] { column0, column1, column2, column3, column4, column5, column6 };
}
