如何逐行、部分地从文本文件中取出数据？

Question

So I've been hitting my head against the wall trying to fill this list box with ID numbers saved into a text file. It's simple enough to get the lines out of the file and put them into a list box like that, but that ID number is also shared with more information that I want to display in other text boxes.

Edit So this is a comma delimited file and here is an example of a student's stored information:

1234561, Hubert, Huphrey, 123 Apple, Townsville, Some State, MM/DD/YYYY

To put it plainly, I have this text file that has multiple ID #'s, Names, and Addresses, but I just want to display the ID #'s so they can be clicked on from their list box so the rest of the information can be displayed on screen.

I have already taken in a lot of advice, but my thick head can't figure out a few key points. Let me start off by sharing the code I have so far:

EDIT I have updated the method to work with the new Student Class. But Now I need to figure out how to work with the collection to get the properties of the class.

        List<Student> colStudents = new List<Student>();
        public MainWindow()
        {
            InitializeComponent();
        }

        private void btnGetStudents_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                //Define a Student object variable with the name StudentInfo
                string strStudentList;
                // Declare a StreamReader variable for Student Object
                StreamReader srStudent = new StreamReader("StudentData.txt");
                // intIndex is the index of the contact chosen
                int intIndex = lstStudentsID.SelectedIndex;

                //Clear list box to avoid having it fill up too much
                lstStudentsID.Items.Clear();

                // Read the disk file structure
                while (srStudent.EndOfStream == false)
                {
                    // Read disk file into a string variable using the ReadLine method.
                    strStudentList = srStudent.ReadLine();
                    // Tokenize the string read from Student object
                    string[] tokenize = strStudentList.Split(',');
                    // Create a student object instance from the Student class.
                    Student StudentInfo = new Student();
                    // Set properties of Student object to array element containing the student data
                    StudentInfo.StudentID = int.Parse(tokenize[0]);
                    StudentInfo.StudentFirstName = tokenize[1];
                    StudentInfo.StudentLastName = tokenize[2];
                    StudentInfo.StudentAddressCity = tokenize[3];
                    StudentInfo.StudnetBirthDate = tokenize[4];
                    // Add student object to collection
                    colStudents.Add(StudentInfo);
                    // Add ID's to the listbox
                    lstStudentsID.Items.Add(StudentInfo.StudentID);
                }
                //Close disk file after all records have been read in
                srStudent.Close();
            }
            catch(Exception ex)
            {
                MessageBox.Show("Experiencing the following disk problems: " + Environment.NewLine + ex.Message, "Disk File", MessageBoxButton.OK, MessageBoxImage.Exclamation);
            }
        }

EDIT : Now that I have the while loop working well enough, I need to either figure out how to utilize the collection or just find a way to use a second and third method to print out the selected student's full name and address

Here's my new class:

public class Student
    {
        // Properties
        private double _ID;  // Student's ID, double just in case int is too small
        private string _StudentFirstName;  // Student's Name
        private string _StudentLastName;
        private string _StudentAddressStreet;
        private string _StudentAddressCity;
        private string _StudentBirthDate;

        // Constructor
        public Student()
        {
            _ID = 0;
            _StudentFirstName = "";
            _StudentLastName = "";
            _StudentAddressStreet = "";
            _StudentAddressCity = "";
            _StudentBirthDate = "";
        }

        // ID Property
        public double StudentID
        {
            get { return _ID; }
            set { _ID = value; }
        }

        // First Name Property
        public string StudentFirstName
        {
            get { return _StudentFirstName; }
            set { _StudentFirstName = value; }
        }

        // Last name Property
        public string StudentLastName
        {
            get { return _StudentLastName; }
            set { _StudentLastName = value; }
        }

        // Address Property
        public string StudentAddressStreet
        {
            get { return _StudentAddressStreet; }
            set { _StudentAddressStreet = value; }
        }

        // Address Property
        public string StudentAddressCity
        {
            get { return _StudentAddressCity; }
            set { _StudentAddressCity = value; }
        }

        // Address Property
        public string StudnetBirthDate
        {
            get { return _StudentBirthDate; }
            set { _StudentBirthDate = value; }
        }
    }

Answer 1

You create dictionary with Key as studentid and value as file line then using dictionary you can populate the list box when user select particular list item retrieve the data from dictionary do not perform IO operation.

Dictionary studentInfo = new Dictionary();

    static void Main(string[] args)
    {


        StreamReader Student = new StreamReader("StudentData.txt");
        // intIndex is the index of the contact chosen
        intIndex = lstStudentsID.SelectedIndex;
        // Add student to colStudents list
        colStudents.Add(Student.ToString());
        // Read the disk file structure
        while (Student.EndOfStream == false)
        {
            // Read disk file into a string variable using the ReadLine method.
            strStudentInfo = Student.ReadLine();
            // Tokenize the string read from Student object
            string[] tokenize = strStudentInfo.Split(',');
            // Create a student object instance from the Student class.
            string temp = tokenize[0];

            studentInfo.Add("Key", strStudentInfo);

        }

    }

Answer 2

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.stream.Stream;

public class TestReadFile {

    public static void main(String args[]) {

        String fileName = "StudentData.txt";

        //read file into stream, try-with-resources
        try (Stream<String> stream = Files.lines(Paths.get(fileName))) {

            stream.forEach(System.out::println);

        } catch (IOException e) {
            e.printStackTrace();
        }

    }
