Question

我有许多文本文件都遵循相同的内容格式：

"Title section","Version of the app"
10
"<thing 1>","<thing 2>","<thing 3>","<thing 4>","<thing 5>","<thing 6>","<thing 7>","<thing 8>","<thing 9>","<thing 10>"

'Where:
'  first line never changes, it always contains exactly these 2 items
'  second line is a count of how many "line 3s" there are
'  line 3 contains a command to execute and (up to) 9 parameters
'      - there will always be 10 qoute-delimited entries, even if some are blank
'      - there can be N number of entries (in this example, there will be 10 commands to read)

我正在使用StreamReader阅读每个文本文件，并希望在自己的类中设置每个文件。

public class MyTextFile{
    public string[] HeaderLine { get; set; }
    public int ItemCount { get; set; }
    List<MyCommandLine> Commands { get; set;}
}

public class MyCommandLine{
    public string[] MyCommand { get; set; }
}

private void btnGetMyFilesiles_Click(object sender, EventArgs e){
    DirectoryInfo myFolder = new DirectoryInfo(@"C:\FileSpot");

    FileInfo[] myfiles = myfolder.GetFiles("*.ses");

    string line = "";
    foreach(FileInfo file in Files ){
        str = str + ", " + file.Name;

        // Read the file and display it line by line.
        System.IO.StreamReader readingFile = new System.IO.StreamReader(file.Name);
        MyTextFile myFileObject = new MyTextFile()

        while ((line = readingFile.ReadLine()) != null){
            ' create the new MyTextFile here
        }
        file.Close();
        }
    }
}

目标是确定所调用的实际命令是什么（＆＃34;＆＃34;），如果任何其余参数指向预先存在的文件，则确定该文件是否存在。我的问题是，我无法弄清楚如何阅读N号＆＃34;第3行＆＃34;到他们自己的对象并将这些对象附加到MyTextFile对象。我99％肯定我已逐渐误入歧途阅读每个文件，但我不知道如何摆脱它。

因此，针对将N个第3行项目纳入您的课程的具体问题，您可以执行类似的操作（显然您可以进行一些更改，因此它更适合您的应用程序）。

public class MyTextFile
{
    public List<Array> Commands = new List<Array>();

    public void EnumerateCommands()
    {
        for (int i = 0; i < Commands.Count; i++)
        {
            foreach (var c in Commands[i])
                Console.Write(c + " ");
            Console.WriteLine();
        }
    }
}


class Program
{
    static void Main(string[] args)
    {
        string line = "";
        int count = 0;
        MyTextFile tf = new MyTextFile();
        using (StreamReader sr = new StreamReader(@"path"))
        {
            while ((line = sr.ReadLine()) != null)
            {
                count += 1;

                if (count >= 3)
                {
                    object[] Arguments = line.Split(',');
                    tf.Commands.Add(Arguments);
                }
            }
        }
        tf.EnumerateCommands();
        Console.ReadLine();
    }
}

至少现在你的“MyTextFile”中有一个命令列表。你可以枚举并做一些事情的课程。

**我添加了EnumerateCommands方法，以便您实际上可以看到列表正在存储订单项。代码应该在控制台应用程序中运行，并使用适当的＆＃39;使用＆＃39;语句。

希望这有帮助。

Answer 2

如果所有内容都以逗号,分隔，您可以执行以下操作：

int length = Convert.ToInt32 (reader.ReadLine ()); string line = reader.ReadLine (); IEnumerable <string> things = line.Split (',').Select (thing => thing. Replace ('\"'', string.Empty).Take(length);

Take表示从该行中获取了多少things。
