C#多维数组像PHP一样

Question

我一直试图这样做大约6个小时了,我很难过......

我希望在C#中等效于此:

    $settings = array();
    foreach(file('settings.txt') as $l) $settings[]=explode(',',$l);
    print $settings[0][2];

这是我到目前为止所做的不起作用:

    string fileName = System.IO.Path.GetDirectoryName(Application.ExecutablePath) + "\\" + "settings.txt";
    string[,] settings;

    FileStream file = null;
    StreamReader sr = null;

    try
    {
        file = new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.Read);
        sr = new StreamReader(file, Encoding.ASCII);
        string[] line;
        int i = 0;
        do
        {
            line = sr.ReadLine().Split(',');
            settings[i++, 0] = line[0];
        } while (line != null);
        file.Close();

        MessageBox.Show(settings[1, 0]);
    } catch (Exception err) { MessageBox.Show(err.Message); }

我得到"对象引用没有设置为对象的实例",任何想法将不胜感激..

使用锯齿状数组而不是多维数组 - 或者更好,a List<string[]>:

var settings = new List<string[]>();

foreach (string line in File.ReadLines("settings.txt", System.Text.Encoding.ASCII))
    settings.Add(line.Split(','));

Marc使用LINQ而不是循环是一个很好的选择.
