I got it when trying to initialize my array of sprites
(( the only one trowing me null is the sprite2D[] AllianceCharacters


declaration:
Code:
sprite2D[] AllianceCharacters;
static string Cardspath = Directory.GetCurrentDirectory() + "\\Content\\Cards";
string[] ActionBar = Directory.GetFiles(Cardspath + "\\ActionBar\\");
        string[] Equips = Directory.GetFiles(Cardspath + "\\ActionBar\\Equips");
        string[] CharactersAlliance = Directory.GetFiles(Cardspath + "\\Characters\\Alliance\\");
        string[] CharactersHorde = Directory.GetFiles(Cardspath + "\\Characters\\Horde\\");
        string[] CharactersMonster = Directory.GetFiles(Cardspath + "\\Characters\\Monster\\");

initialization:
Code:
for (int i = 0; i < CharactersAlliance.Length; i++)
            {

                AllianceCharacters[i] = new sprite2D(Content.Load<Texture2D>(Cardspath + "\\Characters\\Alliance\\" + CharactersAlliance[i]));
                AllianceCharacters[i].name = CharactersAlliance[i];

            }



//This is called at the beginning::
Code:
void FixNames()
        {
            int x, y, z, a, h, m;
           
            y = Equips.Length;
            z = ActionBar.Length;
            a = CharactersAlliance.Length;
            h = CharactersHorde.Length;
            m = CharactersMonster.Length;
           
            char[] xnb = { 'b', 'n', 'x', '.' };

            for (x = 0; x < y; x++)
            {
                Equips[x] = Path.GetFileName(Equips[x]);
                Equips[x] = Equips[x].TrimEnd(xnb);
            }
            for (x = 0; x < z; x++)
            {
                ActionBar[x] = Path.GetFileName(ActionBar[x]);
                ActionBar[x] = ActionBar[x].TrimEnd(xnb);
            }
            for (x = 0; x < a; x++)
            {
                CharactersAlliance[x] = Path.GetFileName(CharactersAlliance[x]);
                CharactersAlliance[x] = CharactersAlliance[x].TrimEnd(xnb);
            }
            for (x = 0; x < h; x++)
            {
                CharactersHorde[x] = Path.GetFileName(CharactersHorde[x]);
                CharactersHorde[x] = CharactersHorde[x].TrimEnd(xnb);
            }
            for (x = 0; x < m; x++)
            {
                CharactersMonster[x] = Path.GetFileName(CharactersMonster[x]);
                CharactersMonster[x] = CharactersMonster[x].TrimEnd(xnb);
            }
        }



any idea on what could be making it fail ?


EDIT:: forget it,.. in the end I figured out myself...

Stop treating C# like a purely procedural imperative programming language. It is object oriented, treat it as such. I suggest you actually learn the language before you continue this project, as the last few posts you've made in this section show you don't even understand the basic constructs.

I'm making this project to learn, this is for self study mostly and my problem was that yeah I'm not used yet to the system, but I think its all about practice.. I mean... I could solve the problem by myself by just looking at the code several times again and again.
