Reading from .txt file, then exporting data to DataGridView

Question

I know this is a laughable question, but God, I\'ve spent my entire last day banging my head with it and it just won\'t work! The goddamn teacher didn\'t even mention anythi

Answer 1

If you already have a User object defined you can add a static method to it that loads the data to a list of users and bind it to the grid view.

public class User {
  public string Id { get; set; }
  public string Name { get; set; }
  public string Surname { get; set; }
  public string Telephone { get; set; }
  public bool Vip { get; set; }
  public int Age { get; set; }
  public decimal Balance { get; set; }

  public static List<User> LoadUserListFromFile(string path) {
    var users = new List<User>();

    foreach (var line in File.ReadAllLines(path)) {
      var columns = line.Split('\t');
      users.Add(new User {
        Id = columns[0],
        Name = columns[1],
        Surname = columns[2],
        Telephone = columns[3],
        Vip = columns[4] == "1",
        Age = Convert.ToInt32(columns[5]),
        Balance = Convert.ToDecimal(columns[6])
      });
    }

    return users;
  }
}

Then you can simply load that into a data grid:

usersDataGridView.DataSource = User.LoadUserListFromFile("user_db.txt");
