        if (txtopen.ShowDialog() == DialogResult.OK)
        {
            string FileName = txtopen.FileName;
            string line;
            System.IO.StreamReader file = new System.IO.StreamReader(FileName.ToString());
            while ((line = file.ReadLine()) != null)
            {
                list.Add(double.Parse(line));
            }
            //To print the arraylist
            foreach (double s in list)
            {
                Console.WriteLine(s);
            }
        }

Solution

I think your list already contains some of the data, you should clear it before adding new file data to it.

OpenFileDialog txtopen = new OpenFileDialog();
if (txtopen.ShowDialog() == DialogResult.OK)
{
    list.Clear();   // <-- clear here

    string FileName = txtopen.FileName;
    string line;
    System.IO.StreamReader file = new System.IO.StreamReader(FileName.ToString());
    while ((line = file.ReadLine()) != null)
    {
        list.Add(double.Parse(line));
    }
    //To print the arraylist
    foreach (double s in list)
    {
        Console.WriteLine(s);
    }
}

Other wise every thing seems to be fine here.
