分割文本文件成二维数组

Question

这是我想分割成二维数组的文本文件

"YHOO",36.86,21,13873900,37.00 "GOOG",684.11,1114,1821650,686.72 "MSFT",50.54,3993,31910300,50.65 "AAPL",94.40,28201,39817000,94.26

这是我实现的代码但是它不起作用

 String input = File.ReadAllText(@"....DatastockInfo.txt");
        int i = 0, j = 0;
        string[,] result = new string[3, 5];
        foreach (var row in input.Split('n'))
        {
            j = 0;
            foreach (var col in row.Trim().Split(','))
            {
                result[i, j] = string.Parse(col.Trim());
                j++;
            }
            i++;
        }

Answer 1

锯齿形数组String[][](数组的数组)通常比二维数组String[,]:

  string[][] result = File
    .ReadLines(@"....DatastockInfo.txt")
    .Select(line => line.Split(','))
    .ToArray();

如果你坚持使用2D数组你就必须使用效率较低的代码

  string[] lines = File.ReadAllLines(@"....DatastockInfo.txt");
  string[,] result = null;
  for (int i = 0; i < lines.Count; ++i) { 
    string[] items = lines.Split(',');
    if (null == result)
      result = new string[lines.Count, items.Length];
    for (int j = 0; j < items.Length; ++j) 
      result[i, j] = items[j];
  }

Answer 2

数组大小错误。此外，你不需要串。解析，因为Split的输出是IEnumerable of strings

int i = 0, j = 0;
string[,] result = new string[4, 5];
foreach (var row in input.Split('n'))
{
    j = 0;
    foreach (var col in row.Trim().Split(','))
    {
        result[i, j] = col.Trim();
        j++;
    }
    i++;
}
