i have used the following to to extract data from a text file & store values in an array-

public class data
        {
            public string date, time, mag, depth;
            public double lat, lon;
        }
        private void view_file_Load(object sender, EventArgs e)
        {

            string str;
            List<data> gd = new List<data>();
            try
            {
                using (StreamReader sr = new StreamReader("C:\\Windows\\Temp\\op.txt"))
                {
                    string line;
                    while ((line = sr.ReadLine()) != null)
                    {
                        string[] arr = line.Split(new char[] { ' ' }, System.StringSplitOptions.RemoveEmptyEntries);
                        while (sr.Peek() > 0)
                        {

                            string[] s = new string[] { " " };
                            char[] c = new char[] { ' ' };
                            str = sr.ReadLine();
                            arr = str.Split(c);

                            data d = new data();
                            d.date = arr[0];
                            d.time = arr[1];
                            d.lat = Convert.ToDouble(arr[3]);
                            d.lon = Convert.ToDouble(arr[4]);
                            d.depth = arr[7];
                            d.mag = arr[8];


                        }

now i want to store those array values into access database, how do i achieve this?
