SerializedProperty with children class fields

Question

 public class MyClass {
     public string name;
 }
 
 public class MyChildrenClass : MyClass {
     public int live  = 10;
 }
 
 public class MyObject : ScriptableObject {
     public MyClass myClass = new MyChildrenClass();
 }

How can I get the MyChildrenClass properties form the SerializedProperty?

 SerializedObject object = new SerializedObject(new MyObject());
 SerializedProperty myClassSerialized = object.FindProperty("myClass");
 
 //Doesnt get live property becouse it's interpretated as "MyClass"
 SerializedProperty m_live = myClassSerialized.FindPropertyRelative("live");

You can iterate through child props of serialised classes by using an enumerator. You can do this a couple different ways, one being using GetEnumerator:

 var childEnum = serializedObject.FindProperty("myClass").GetEnumerator();
 while (childEnum.MoveNext())
 {
     var current = childEnum.Current as SerializedProperty;
     if (current.name == "live")
     {
         // Do things
     }
 }

Or you can use Next or NextVisible with the enterChildren argument set to true:

 var myClassProps = serializedObject.FindProperty("myClass");
 while (myClassProps.NextVisible(true))
 {
     if (myClassProps.name == "live")
     {
         // Do things
     }
 }

You can use property.GetEndProperty() and SerializedProperty.EqualContents():

             public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
             {
                 var endProperty = property.GetEndProperty();
                 while (property.NextVisible(true))
                 {
                     if (SerializedProperty.EqualContents(property, endProperty))
                     {
                         break;
                     }
                    ...
