从text读内容存放二维数组的问题。急

[right89757]

0, 40.123, -1.231, 10.59,
1, 40.230, -1.242, 10.51,
2, 40.235, -1.2425, 0,
3, 40.545, -1.9483, 10.35,
4, 40.015, -1.0473, 11.00,
text文件中存放这样一组数据。运行时输入两个点（例如0,1），计算这两个点的距离。
我先把上述内容存放在list中，然后split存放在二维数组Coor。
可是现在运行有错误，不知道错哪了。
错误提示：未经处理的异常： system.IndexOutOfRangeException:索引超出的数组范围

                {
                    col[i] = Convert.ToString(row[i]);

                }
                list.Add(col);

            }

            string[][] Coor = list.ToArray();
            Console.WriteLine(Coor[0][0]);
            
        }

不用搞那么复杂，只要4行代码就行了：

		string[] rows = File.ReadAllLines(@"E:\nottingham\study\PRG\Projects\distance_P2P\distance_P2P\Coordinate.txt");
		string[][] values = new string[rows.Length][];
		for (int i = 0; i < rows.Length; i++)
			values[i] = rows[i].Split(',');
		//以下是输出各元素的值
		for (int i = 0; i < values.Length; i++)
		{
			for (int j = 0; j < values[i].Length; j++)
				Console.Write(values[i][j] + "    ");
			Console.WriteLine();
		}

string[] lines = File.ReadAllLines("路径");
string[][] mylist = new string[lines.Length][];
for (int i = 0; i < lines.Length; i++)
{
mylist[i] = lines[i].Split(',');
}

啊，看到每行最后还多了个逗号，那么改成这样：

		string[] rows = File.ReadAllLines(@"E:\nottingham\study\PRG\Projects\distance_P2P\distance_P2P\Coordinate.txt");
		string[][] values = new string[rows.Length][];
		for (int i = 0; i < rows.Length; i++)
			values[i] = rows[i].Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
		//以下是输出各元素的值
		for (int i = 0; i < values.Length; i++)
		{
			for (int j = 0; j < values[i].Length; j++)
				Console.Write(values[i][j] + "    ");
			Console.WriteLine();
		}
