我有一个看起来像这样的文本文件

11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30

91 92 93 94 95 96 97 98 99 100
in a 10 x 10 grid. using c# I need to take the text file and turn it into a 2d array of integers so that I can manipulate the integers on an independent level. Please help cant work it out,
在 10 x 10 的网格中。使用 c# 我需要获取文本文件并将其转换为二维整数数组，以便我可以在独立级别上操作整数。请帮助解决不了，

String input = File.ReadAllText( @"c:\myfile.txt" );
int i = 0, j = 0;
int[,] result = new int[10, 10];
foreach (var row in input.Split('\n'))
{
j = 0;
foreach (var col in row.Trim().Split(' '))
{
result[i, j] = int.Parse(col.Trim());
j++;
}
i++;
}
The indices will be 0-basedso if you want to access 10thcolumn in fourthrow:
索引将从0 开始，因此如果您想访问第四行的第 10列：
Console.WriteLine(result[3,9]); //40

Perhaps:
也许：
var result = File.ReadLines(path)
.SelectMany((l, i) => l.Split()
.Select(s => new int[] { i, int.Parse(s) })
.ToArray())
.ToArray();
Edit: Although this is a jagged array int[][].
编辑：虽然这是一个锯齿状数组int[][]。
