Minimal Sample

This trivial sample shows the use of most of the classes mentioned above:

Note that in most debugging situations the default Realm will be retained so if you run this sample fragment multiple times you should see the number created increase. This is on purpose so you are assured the database is being persisted between runs.

1 using Realms;
3 class Hero : RealmObject
4 {
5  public string SuperName { get; set; }
6  public int SuperScore { get; set; }
7 }
9 /// put this code in an OnLoad or simple button-press handler
11  var _realm = Realm.GetInstance();
12  using (var trans = _realm.BeginWrite())
13  {
14  var hero = _realm.CreateObject<Hero>();
15  hero.SuperName = "Thor";
16  hero.SuperScore = 100;
17  trans.Commit();
18  }
19  var numAwe = _realm.All<Hero>().Count();
20  System.Diagnostics.Debug.WriteLine($"Created {numAwe} heroes");
21  _realm.Close();
