Question

Well basicly had some trouble with placing my teams like so: http://pastebin.com/ahgP04bU

So I asked someone for advice and he just gave me a tip. And he said it has something to do with arrays. Follwing that he sended me a this code…

  string[,] clubs = new string[20,30];

  clubs[0,1] = “spain”;

  clubs[0,2] = etc;

What I don’t understand is those comma’s. And what does that [20,30] indicate?
And how does this help me place my teams in the way I want it (look on the pastebin link).

Or if you think you have a better link for me to help me out with arrays in datasets I would appreciate it.

best regards,

Answer 1

new string[20,30] creates a new multi-dimensional array. Where 20 indicates the array-width and 30 the array-height. Think of it like this:

If you create an array with the width 5 and height 5, you are basically creating 5*5 “slots” for strings that you can set. You can access a specific slot by its coordinates.

This code:

string[,] clubs = new string[5,5];
clubs[0, 1] = "a";
clubs[1, 4] = "b";
clubs[3, 2] = "c";

Creates an array like this:

    0   1   2   3   4
0   ""  ""  ""  ""  ""
1   "a" ""  ""  ""  ""
2   ""  ""  ""  "c" ""
3   ""  ""  ""  ""  ""
4   ""  "b" ""  ""  ""
