XML : Ignoring null references when de-serializing a massive XML document

I'm getting a massive payload of XML from my WCF service, and I need to write it into a SQL database. I'm using the latest version of .NET and Entity Framework 6.

"Okay, that's great," you may say, "but what's the question?"

Well, the XML is being deserialized into C# objects (generated from paste-special) and they're working just great. However, whenever the payload from the service does not contain some field, I get a null reference exception when I'm writing the XML object over to the EF object (This is a class method):

  public ICollection<object> GetObjects()  {      List<object> objs = new List<object>();        foreach (var i in XmlObject.SubObj.SubObj.SubObj)      {          objs.Add(new MyEfObject() {              Prop1 = XmlObject.SubObj.SubObj.SubObj.ObjProperty // If "ObjProperty" is null,                                                                 // I get a null reference exception          });      }        return objs;  }    

So, I have really inelegant code to check

  if (!ReferenceEquals(XmlObject.SubObj.SubObj.SubObj.ObjProperty, null) {      // Do stuff  }    

This would normally be fine, but the object is so large and I want to avoid typing this 150+ times (and for all the object properties of the object).

There has to be a more elegant way, no?
