我只需要从前五列中检索数据，如下所示：

ASPEGIC | ACETYLSALCICYLATE DE LYSINE | 1G | B/6 AMP

到目前为止我用来拆分的代码是

    using (StreamReader sr = new StreamReader("medic.txt"))
    {
        while (sr.Peek() > 0)
        {
            string line = sr.ReadLine();
            var pts = line.Split(" ", StringSplitOptions.RemoveEmptyEntries);
            Array.ForEach(pts, Console.WriteLine);
        }
    }

数据是固定宽度的列，因此请使用以下内容：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Data;
namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.txt";
        static void Main(string[] args)
        {
            FIX_WIDTH fixWidth = new FIX_WIDTH(FILENAME);
        }
    }
    public class FIX_WIDTH
    {
        int[] Start_Position = { 0, 55, 105, 135, 155, 176, 207, 215, 219, 223, 243, 264};
        string[] Column_Names = { "Col_A", "Col_B", "Col_C", "Col_D", "Col_E", "Col_F", "Col_G", "Col_H", "Col_I", "Col_J", "Col_K", "Col_L" };
