从txt文件中读取数据并将其添加到可观察的集合中

Question

I'm attempting to build a simple save-and-load program that reads Users in from a text file, adds it to an observable collection, and then populates a listbox with the observable collection of Users.

While I understand how to add Users to my observable collection and then write that collection to the the txt file, I am confused as to how I am supposed to read-in a user and re-add him to the the ObservableCollection of users.

my user class:

public class User
{
    public string UserName { get; set; }
    public string Password { get; set; }
}

Problem method:

 ObservableCollection<User> LoadActionList = new ObservableCollection<User>();
        using (System.IO.StreamReader file = new System.IO.StreamReader("SavedAccounts.txt"))
        {
            string line;
            while (!file.EndOfStream)
            {
                line = file.ReadLine();
                //LoadActionList.Add(line); //how to detect that a line is a User?
            }
            file.Close();
        }

Any ideas?

Instead of writing text files for this you should look into serialization.
