私は、同じテキスト ファイルにあるサッカー リーグと備品を読み取るプログラムを作成しています。リーグ情報は上位 32 行で、備品はドキュメントの残りの部分です。とにかく、プログラムを実行して、リストボックスに表示されるリーグ情報 (名前、スポンサーなど) だけを取得しようとすると、テキスト全体からランダムなコード行が取得されます。上位32行のみが表示されるように修正する方法はありますか?

 public partial class frmLeaguesAndFixtures : Form
 {
    public static frmLeagues frmkeepLeagues = null;
    ArrayList leaguesArray = new ArrayList();
    public static string inputDataFile = @"E:\Soft130\CW\SOFT130GroupAssignment\SOFT130GroupAssignment\Assignment\bin\Debug\football.txt";
    const int numLeagueItems = 8;

    public frmLeaguesAndFixtures()
    {
        InitializeComponent();
    }

    private bool fileOpenForReadOK(string readFile, ref StreamReader dataIn)
    {
        try
        {
            dataIn = new StreamReader(readFile);
            return true;
        }
        catch (FileNotFoundException notFound)
        {
            MessageBox.Show("ERROR Opening file (when reading data in) - File could not be found.\n"
                                                            + notFound.Message);
            return false;
        }
        catch (Exception e)
        {
            MessageBox.Show("ERROR Opening File (when reading data in)- Operation failed.\n"
                                                            + e.Message);
            return false;
        }
    }

     public static bool getNextLeague(int numItems, StreamReader inNext, string[] nextLeagueData)
     {
        //locals
        string nextLine;
        int numDataItems = numItems;

        //read nextdata - based on constant numDataItems
        for (int i = 0; i < numDataItems; i++)
        {
            try
            {
                nextLine = inNext.ReadLine();
                if (nextLine != null)
                    nextLeagueData[i] = nextLine;
                else
                {
                    return false; //no more full data to process 
                }
            }
            catch (Exception e)
            {
                System.Windows.Forms.MessageBox.Show("ERROR Reading from file. Incomplete Data.\n" + e.Message);
                return false; //problem - could not read file
            }
        }
        return true;//no problems 
    }

    private void readLeague()
    {
       string inLeagueName, string inLeagueSponsor, int inLeaguePrize, int inLeagueNumFixtures)

        //local variables
        StreamReader inLeague = null;
        Leagues tempLeague;
        bool anyMoreLeagues = false;
        string[] leagueData = new string[numLeagueItems];

        //if file opened ok proceed

            //loop for all FULL league   in file
            while (anyMoreLeagues == true)
            {
                //create new league
                tempLeague = new Leagues(leagueData[0], leagueData[1], leagueData[2], leagueData[3]);

                //store in array
                leaguesArray.Add(tempLeague);

                //DOESNT WORK CORRECTLY TRY IT USING "PREMIERSHIP"
                // if (leagueData[0] == "The Championship")
                    {
                        foreach (Leagues l in leaguesArray)
                        {
                            lstLeagueInfo.Items.Add(l.getLeagueName() + " " + l.getLeagueSponsor() + " " + l.getLeaguePrize() + " " + l.getLeagueNumFixtures());
                        }

        }

var top32Lines = File.ReadLines(filename).Take(32).ToList();

これを使用して残りの行を取得します。

var allLines = File.ReadeLines(filename).ToList();
var first32 = allLines.Take(32).ToList();
var rest = allLines.Skip(32).ToList();

これが役立つことを願っています

更新 1:

これらの行を通過するには、 を使用しますforeach。

//example
foreach(string line in first32)
{
    //do your work
}
