Hallo Jonny,
ich habe mir noch mal alles durchgelesen (auch deine frühere Frage "Schummeleditor") und mich gefragt (weil heute Ostern ist ;-)), ob dir mit einem konkreten Beispiel vielleicht besser geholfen werden kann. Hier mal ein Entwurf, der möglicherweise
Hilfreich ist:
Die Klasse "Player". Jeder Player bekommt später seine eigene Instanz :
public class Player {
private int mScore;
public int Score {
get { return mScore; }
set { mScore = value < 0 ? 0 : value; }
}
private string mPlayerName;
public string PlayerName {
get { return mPlayerName; }
set { mPlayerName = string.IsNullOrEmpty(value) || value.Trim() == string.Empty ? "-" : value; }
}
public Player(int pScore, string pPlayerName) {
Score = pScore;
PlayerName = pPlayerName;
}
public Player() {
Score = 0;
PlayerName = "-";
}
public Player Copy() {
return new Player(Score, PlayerName);
}
public override string ToString() {
return Score.ToString() + " " + PlayerName;
}
}
Und hier die Klasser "PlayerListe" zur Verwaltung der Player:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
public class PlayerListe {
private List<Player> player;
public PlayerListe() {
player = new List<Player>();
Normalize();
}
public PlayerListe(string pDatei) : this() {
try {
ReadTop10(pDatei);
} catch ( Exception ) {}
}
public Player GetPlayer(int pPosition) {
if ( pPosition < 0 || pPosition > 9 ) { return null; }
return player[pPosition];
}
public void SetPlayer(int pPosition, Player pPlayer, bool pAutoSort = true) {
if ( pPosition < 0 || pPosition > 9 ) { return; }
player[pPosition] = pPlayer;
if (pAutoSort) { Normalize(); }
}
public void SetPlayer(int pPosition, int pScore, string pName, bool pAutoSort = true) {
if (pPosition < 0 || pPosition > 9) { return; }
player[pPosition].Score = pScore;
player[pPosition].PlayerName = pName;
if ( pAutoSort ) { Normalize(); }
}
public void SetPlayer(int pPosition, int pScore, bool pAutoSort = true) {
if ( pPosition < 0 || pPosition > 9 ) { return; }
player[pPosition].Score = pScore;
if ( pAutoSort ) { Normalize(); }
}
public void DeletePlayer(int pPosition, bool pAutoSort = true) {
if ( pPosition < 0 || pPosition > 9 ) { return; }
player[pPosition].Score = 0;
player[pPosition].PlayerName = "-";
Normalize();
}
public bool ReadTop10(string pFileName) {
if ( !File.Exists(pFileName) ) {
WriteTop10(pFileName);
}
using ( BinaryReader br = new BinaryReader(File.Open(pFileName, FileMode.Open, FileAccess.Read, FileShare.None)) ) {
try {
player.Clear();
for ( int i = 0 ; i < 10 ; i++ ) {
player.Add(new Player(br.ReadInt32(), br.ReadString()));
}
return true;
} catch ( Exception ) {
// Fehlerbehandlung ergänzen
return false;
}
}
}
public bool WriteTop10(string pFileName) {
Normalize();
using ( BinaryWriter br = new BinaryWriter(File.Open(pFileName, FileMode.Create, FileAccess.Write, FileShare.None)) ) {
try {
for ( int i = 0 ; i < 10 ; i++ ) {
br.Write(player[i].Score);
br.Write(player[i].PlayerName);
}
return true;
} catch ( Exception ) {
// Fehlerbehandlung ergänzen
return false;
}
}
}
public PlayerListe Copy() {
PlayerListe myCpoy = new PlayerListe();
for (int i = 0 ; i< player.Count ; i++ ) {
myCpoy.SetPlayer(i, player[i].Copy(), false);
}
return myCpoy;
}
private void Normalize() {
if ( player.Count < 10 ) {
int cnt = player.Count;
for ( int i = cnt ; i < 10 ; i++ ) {
player.Add(new Player(0,"-"));
}
}
player = Sort();
if ( player.Count > 10 ) {
for ( int i = player.Count ; i < 10 ; i-- ) {
player.RemoveAt(i);
}
}
return;
}
private List<Player> Sort() {
IEnumerable<Player> sortiert =
from p in player
orderby p.Score descending, p.PlayerName ascending
select p;
return sortiert.ToList<Player>();
}
}
Präsentation der Daten, Editor als WinForm. Auf das Form packst du 10 Textboxen, die du als textBoxName_n (n = 0 bis 9), 10 weitere Textboxen textBoxScore_n (n = 0 bis 9) und einen Button namens "buttonSpeichern:
using System;
using System.Collections.Generic;
using System.Windows.Forms;
namespace Schummeleditor {
public partial class FormEditor : Form {
public FormEditor() {
InitializeComponent();
}
private PlayerListe myPlayers;
private string datei = @"\score.dat";
private List<TextBox> nameBoxes;
private List<TextBox> scoreBoxes;
private void FormEditor_Load(object sender, EventArgs e) {
nameBoxes = new List<TextBox>() {
textBoxName_0, textBoxName_1, textBoxName_2,
textBoxName_3, textBoxName_4,textBoxName_5,
textBoxName_6, textBoxName_7,textBoxName_8,
textBoxName_9 };
scoreBoxes = new List<TextBox>() {
textBoxScore_0, textBoxScore_1, textBoxScore_2,
textBoxScore_3, textBoxScore_4,textBoxScore_5,
textBoxScore_6, textBoxScore_7,textBoxScore_8,
textBoxScore_9 };
LoadToEditor();
}
private void buttonSpeichern_Click(object sender, EventArgs e) {
StorePlayers();
}
private void LoadToEditor() {
myPlayers = new PlayerListe(datei);
for (int i=0 ; i < 10 ; i++ ) {
nameBoxes[i].Text = myPlayers.GetPlayer(i).PlayerName;
scoreBoxes[i].Text = myPlayers.GetPlayer(i).Score.ToString();
}
}
public void StorePlayers() {
// Anwendung: .SetPlayer(Postition, Score, Name, Sortieren)...
for ( int i = 0 ; i < 10 ; i++ ) {
int score;
if (int.TryParse(scoreBoxes[i].Text, out score) && score >= 0) {
myPlayers.SetPlayer(i, score, nameBoxes[i].Text, false);
}
}
myPlayers.WriteTop10(datei);
LoadToEditor();
}
}
}
Die Präsentation der Daten musst du natürlich ggf. anpassen.
