问题描述

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。我尝试将其提取到表单中,但这会使它产生混乱,并且我肯定这是一种糟糕的方法。有人可以建议一种方法吗?

as the title suggests im trying to send a file acquired by stream reader to another class so that that class can extract the information from it. I have tried extracting it within the form but this makes it confusing and im certain is a poor way of doing it. Can anyone suggest a way?

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))
                {

                }
            }
        } 

现在我需要某种方式将其发送到这里...我看不到如何:[

Now I need some way of sending it here... I can't see how :[

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

推荐答案

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。 / p>

I would just pass the path of the file to your class and then open the file for reading.

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或方法本身中传递路径作为参数。

You could pass the path in the constructor of the class or to the method itself as a parameter.
