Can we make a relation between two Generic Lists?

Can we eatablish any relation between two lists?I just want to query the list and find the related result from other list.Please suggest some idea

class GeneralClass
    {
        //public List<int> Student_RollNumber = new List<int>();
        //public List<string> Student_Name = new List<string>();
        private List<int> _student_rollnumber = new List<int>();
        private List<string> _student_name = new List<string>();
        public List<int> Student_RollNumber
        {
            get { return _student_rollnumber; }
            set { _student_rollnumber = value; }
        }
        public List<string> Student_Name
        {
            get { return _student_name; }
            set { _student_name = value; }
        }
    }

private void btn_save_Click(object sender, EventArgs e)
        {
            try
            {
                obj.Student_RollNumber.Add(int.Parse(txtbx_rollnum.Text));
                obj.Student_Name.Add(txtbx_SName.Text);
                MessageBox.Show("Data saved");
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "Message from form");
            }
        }
        private void button2_Click(object sender, EventArgs e)
        {
            try
            {
               var result = obj.Student_Name.Contains(txtbx_find.Text).ToString();
              MessageBox.Show(result.ToString());
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

Here i want the Student name when i search for Rollnumber.Can we have multiple column's in a List.

为什么不创建一个新的自定义类并将其用作通用参数？

class Student
{
  public Student(int rollNumber, string name)
  {
    Name = name;
    RollNumber = rollNumber;
  }

  public string Name { get; private set; }
  public int RollNumber { get; private set; }
}

class GeneralClass
{
  private List<Student> students = new List<Student>();
  public List<Student> Students
  {
    get { return students; }
  }
}

private void btn_save_Click(object sender, EventArgs e)
{
  try
  {
    int rollNumber = int.Parse(txtbx_rollnum.Text);
    string name = txtbx_SName.Text;
    obj.Add(new Student(rollNumber, name));
    MessageBox.Show("Data saved");
   }
   catch (Exception ex)
   {
     MessageBox.Show(ex.Message, "Message from form");
   }
}
