Aggregate multiple arrays into one array (Linq)

I'm having trouble aggregating multiple arrays into one "big array", I think this should be possible in Linq but I can't get my head around it :(

consider some method which returns an array of some dummyObjects

public class DummyObjectReceiver 
{
  public DummyObject[] GetDummyObjects  { -snip- }
}

now somewhere I have this:

public class Temp
{
  public List<DummyObjectReceiver> { get; set; }

  public DummyObject[] GetAllDummyObjects ()
  {
    //here's where I'm struggling (in linq) - no problem doing it using foreach'es... ;)
  }
}

hope it's somewhat clear what I'm trying to achieve (as extra I want to order this array by an int value the DummyObject has... - but the orderby should be no problem,... I hope ;)

From stackoverflow

• You use the SelectMany method to flatten the list of array returning objects into an array.

  public class DummyObject {
   public string Name;
   public int Value;
  }
  
  public class DummyObjectReceiver  {
  
   public DummyObject[] GetDummyObjects()  {
    return new DummyObject[] {
     new DummyObject() { Name = "a", Value = 1 },
     new DummyObject() { Name = "b", Value = 2 }
    };
   }
  
  }
  
  public class Temp {
  
   public List<DummyObjectReceiver> Receivers { get; set; }
  
   public DummyObject[] GetAllDummyObjects() {
    return Receivers.SelectMany(r => r.GetDummyObjects()).OrderBy(d => d.Value).ToArray();
   }
  
  }
  

  Example:

  Temp temp = new Temp();
  temp.Receivers = new List<DummyObjectReceiver>();
  temp.Receivers.Add(new DummyObjectReceiver());
  temp.Receivers.Add(new DummyObjectReceiver());
  temp.Receivers.Add(new DummyObjectReceiver());
  
  DummyObject[] result = temp.GetAllDummyObjects();
  

  AnthonyWJones : +1. I missed the "multiple" aspect in my now deleted answer.

  Calamitous : exactly what I was looking for :) extra thanks for including orderby! (still can only +1)
