C#逐行解析文本数据

Question

我的项目有问题，让我在这里解释一下，我在这里需要一些专家指导，因为我是编程新手。 我在记事本中有这样的数据:

10192 20351 30473 40499 50449 60234    
10192 20207 30206 40203 50205 60226    
10192 20252 30312 40376 50334 60252

它是26行数据，但我只显示3行只是为了举例。这是一些按优先级排序的规则:

-我只想读取文本文件然后提取数字。例如:10192 20351 等等。

-我有 6 列的 ListView，我想在它的列中显示每一行数字

Column 1 | Column 2 | Column 3 |Column 4 | Column 5 | Column 6

10192   | 20351   | 30473  | 40499  |50449  | 60234

-当然，如果可能的话，每 5 位数字的前 2 位数字是唯一代码，我只需要最后 3 位数字。例如:192 351 473 499 234。因此每个数字都将以 10.000 为模数。

我想我让很多人感到困惑，抱歉，这是我当前的代码

私有(private)委托(delegate) void UpdateUiTextDelegate(String Text); private void serial_DataRecieved(对象发送者，System.IO.Ports.SerialDataReceivedEventArgs e) { //将接收到的字符收集到我们的“缓冲区”(字符串)中。 字符串接收到的数据； received_data = serial.ReadExisting(); Dispatcher.Invoke(DispatcherPriority.Send, new UpdateUiTextDelegate(WriteData), received_data);

    private void WriteData(String Text)
    {
        if (bufferData != "" || Text[0] == '1')
            bufferData += Text;
        if (bufferData.Length >= 35)
        {
            using (System.IO.StreamWriter file = new System.IO.StreamWriter(@"C:\Users\Rads\Desktop\Training06.txt", true))
            {
                file.WriteLine(bufferData);
            }
            listBox1.Items.Add(bufferData);
            bufferData = "";
        }
    }
    #endregion

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {

    }

    //Browse .txt file
    private void Browse_btn_Click(object sender, RoutedEventArgs e)
    {
        Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();

        dlg.DefaultExt = ".txt";
        dlg.Filter = "Text document (.txt)|*.txt";

        Nullable<bool> result = dlg.ShowDialog();

        if (result == true)
        {
            string filename = dlg.FileName;
            textBox.Text = filename;
        }
    }

    private void Parsing_String(string filename)
    {
        List<Row> list = new List<Row>();

        foreach (String str in File.ReadLines(filename))
        {
            String[] strCols = str.Split(Convert.ToChar(" "));
            list.Add(new Row()
            {
                Column1 = strCols[0].Substring(2),
                Column2 = strCols[1].Substring(2),
                Column3 = strCols[2].Substring(2),
                Column4 = strCols[3].Substring(2),
                Column5 = strCols[4].Substring(2),
                Column6 = strCols[5].Substring(2),


            });
        }

        dg.ItemsSource = list;
    }

    public class Row
    {
        public string Column1 { get; set; }
        public string Column2 { get; set; }
        public string Column3 { get; set; }
        public string Column4 { get; set; }
        public string Column5 { get; set; }
        public string Column6 { get; set; }

    }

非常感谢，如果有人能帮助我..

我认为您根本不需要 Regex。你只需要 string.Split按行和按空格。

string[] lines = data.Split(Enviroment.NewLine);

对于每一行，您可以通过空格分割行来获取字段。

string[] fields = line.Split(' ');
