这是现在的代码,我将包含程序的所有代码,因为我之前遗漏了一些代码。由于您的帮助,我已更改的位我用星号和/// 强调了第一个类是直接编辑表单时从 Windows 窗体创建的标准类。
namespace DistanceEstimatorFinal
{
public partial class Form1 : Form
{
private bool saved;
public Form1()
{
dataPoints mydataPoints = new dataPoints();
InitializeComponent();
dataPoint a = mydataPoints.getItem(0);
latTextBox.Text = a.CurLatitude;
longTextbox.Text = a.CurLongtitude;
eleTextBox.Text = a.CurElevation;
saved = true;
}
private void latTextBox_TextChanged(object sender, EventArgs e)
{
}
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))
{
*var dp = new dataPoints (ofd.FileName);* /////
}
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (saved)
{
if (MessageBox.Show("Save?", "Data Not Saved", MessageBoxButtons.YesNo).Equals(DialogResult.Yes))
{
SaveFileDialog sfd = new SaveFileDialog();
sfd.ShowDialog();
}
}
}
private void saveAsToolStripMenuItem_Click(object sender, EventArgs e)
{
SaveFileDialog sfd1 = new SaveFileDialog();
sfd1.Filter = "CSV files (*.csv)|*.csv|Text files ( *.txt)|*.txt |All files (*.*)|*.*";
sfd1.ShowDialog();
}
}
}
此类旨在从文件中读取数据,我目前正在调整它以从 open 函数中读取文件。
namespace DistanceEstimatorFinal
{
public class dataPoints
{
List<dataPoint> Points;
string p;
public dataPoints(string path)
{
p = path;
Points = new List<dataPoint>();
StreamReader tr = new StreamReader(p);
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;
}
}
}
该文件包含三个变量距离、纬度和经度。
namespace DistanceEstimatorFinal
{
class dataPoint
{
private string latitude;
private string longtitude;
private string elevation;
public dataPoint() //Overloaded incase no value available
{
latitude = "No Latitude Specified";
longtitude = "No Longtitude Specified";
elevation = "No Elevation Specified";
}
public dataPoint(string Latitude, string Longtitude, string Elevation)
{
// TODO: Complete member initialization
this.latitude = Latitude;
this.longtitude = Longtitude;
this.elevation = Elevation;
}
public string CurLongtitude { get { return this.longtitude; } }
public string CurLatitude { get { return this.latitude; } }
public string CurElevation { get { return this.elevation; } }
}
