Question

Answer 1

A:

I would solve it like this:

class Parent
{

  public Parent()
  {
    Children = new Child[3];
  }

  public Child[] Children { get; private set; }

  private Child1 { get { return Child[0]; } set { Child[0] = value; } }
  private Child2 { get { return Child[1]; } set { Child[1] = value; } }
  private Child3 { get { return Child[2]; } set { Child[2] = value; } }
}

The easily map it as separate properties.

<property name="Child1" />
<property name="Child2" />
<property name="Child3" />

Probably best solution is to just map it to another table.

<array table="Children">
  <key name="Parent_FK"/>
  <index name="array_index"/>
  <composite-element>
    <property name="Foo"/>
    <property name="Bar"/>
  </composite-element>
</array>

it would be nice if I had only 3 Child items.. but there are 10 and every Child item contain 5 fields..is there any other solution?

You always need to specify all the columns you have in the database in your mapping file. If there is 10 times the same 5 fields, you need to map 50 columns, there is no way around. If you want to avoid it, avoid this 50 columns and map the whole stuff into another table.
