试图将文件发送到C#中的另一个类

Question

正如标题所示,我试图将流阅读器获取的文件发送到另一个类,以便该类可以从中提取信息.我已经尝试在表单中提取它但这使得它令人困惑,并且我确定这是一种糟糕的方式.谁能提出建议？

这是标识文件的类..

namespace DistanceEstimatorFinal
{
    public partial class Form1 : Form


        private void openDataListToolStripMenuItem_Click(object sender, EventArgs e)
        {
            OpenFileDialog ofd = new OpenFileDialog();
            ofd.Filter = "CSV files (*.csv)|*.csv|Text files ( *.txt)|*.txt |All files (*.*)|*.*";
            if (ofd.ShowDialog(this).Equals(DialogResult.OK))
            {
                Stream fileStream = ofd.OpenFile();

                using (StreamReader reader = new StreamReader(fileStream))
                {

                }
            }
        } 

现在我需要一些方法将它发送到这里......我看不出如何:[

namespace DistanceEstimatorFinal
{

    public class dataPoints
    {
        List<dataPoint> Points;
        public dataPoints( )
        {
            Points = new List<dataPoint>();
            TextReader tr = new StreamReader();
            string input;
            while ((input = tr.ReadLine()) != null)
            {
                string[] bits = input.Split(',');
                dataPoint a = new dataPoint(bits[0],bits[1],bits[2]);              
                Points.Add(a);  


            }

            tr.Close();
        }

        internal dataPoint getItem(int p)
        {
            if (p < Points.Count)
            {
                return Points[p];
            }
            else
                return null;
        }
    }

}

任何帮助将不胜感激

我只是将文件的路径传递给您的类,然后打开文件进行读取.

if (ofd.ShowDialog(this).Equals(DialogResult.OK))
{
    var path = ofd.FileName;

    //Pass the path to the dataPoints class and open the file in that class.
}

您可以在类的构造函数中传递路径,也可以将方法本身作为参数传递.
