c# - 如何从文本文件中获取 2 个数据点

Question

我有一个文本文件，其中有一些要点:

20,30
5,40
67,34
2,0
98,34

如何将这个点添加到列表中？这是我编写的代码:

Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
dlg.DefaultExt = ".txt";
dlg.Filter = "Text document (.txt)|*.txt";

Nullable<bool> result = dlg.ShowDialog();

if (result == true)
{
    string filename = dlg.FileName;
    _mn.nazwa_pliku.Text = filename;

    int num = 0; //get a number of points/line in file

    for (int i = 0; i < num; i++) //for everyone line/point
    {

        int x = 0; //get X-value from file
        int y = 0; //get Y-value from file

        Klaster klaster = new Klaster();
        klaster.Punkty.Add(new Point(x, y));
        Klastry.Add(klaster);
    }       
}

    void LoadCordinates()
    {
        StreamReader sr = new StreamReader("PATH OF FILE");

        Klaster klaster = new Klaster();
        while(sr.EndOfStream == false)
        {
           string temp = sr.ReadLine();
           if(temp.Contains(',') && temp.Split(',').Length == 2)
           {
               klaster.Punkty.Add(new Point(int.Parse(temp.Split(',')[0].Trim()), int.Parse(temp.Split(',')[0].Trim())));
               Klastry.Add(klaster);
           }
        }
    }
