从text读内容存到二维数组使用的问题
点 纬度 经度 海拔
0, 40.123, -1.231, 10.59
1, 40.230, -1.242, 10.51
2, 40.235, -1.2425, 0

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。
怎么从text读内容存到二维数组

暂时只写成这样。。

C# code

 static void Main(string[] args)        {            string[][] Coor;    //存放坐标的二维数组            Coor = new string[3][];            TextReader tr = new StreamReader(@"E:\nottingham\study\PRG\Projects\distance_P2P\distance_P2P\Coordinate.txt");                        string rd="";            while ((rd = tr.ReadLine()) != null)            {                string[] row = rd.Split(',');                            }                    }

[解决办法]
File.ReadAllLines("")
再split分割
[解决办法]
foreach(string s in File.ReadAllLines(""))
{
string[] arr=s.Split(',');

}
[解决办法]

C# code

        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();        }
[解决办法]
 string[] temp = System.IO.File.ReadAllLines("E:\\aaa.txt", System.Text.Encoding.GetEncoding("gb2312"));
           Dictionary<int, product> dic = new Dictionary<int, product>();
           foreach (string s in temp)
           {
                   string[] pInfo = s.Split(',');
                   int id = int.Parse(pInfo[1]);
                   if (!dic.ContainsKey(id))
                   {
                       product p = new product();
                       p.id = id;
                       p.name = pInfo[2];
                       p.count = int.Parse(pInfo[3]);
                       p.remarks = pInfo[4];
                       dic.Add(id, p);
                   }
           }
           foreach (int i in dic.Keys)
           {
               product p = dic[i];
               Console.WriteLine("Id:{0},name:{1},count:{2},remarks:{3},goodproductNo:{4},badproductNo:{5}", p.id, p.name, p.count, p.remarks, p.goodproductNo, p.badproductNo);
           }
