Question

I have this code :

IList<MyObject> myObjects = new List<MyObject>();
if (param != null)
{
    myObjects = (from ... LINQ1 ...).ToList();
}
else
{
    myObjects = (from ... LINQ2 ...).ToList();
}

foreach (MyObject myObject in myObjects)
{
}

when the foreach start, I get a System.NullReferenceException. Why? And how can I fix it? Looks strange…

Answer 1

Your object is being overwritten by one of the LINQ queries which is most likely returning a null value.

Also is myObjects meant to be an IList<MyObject> or List<MyObject> ?
