Question

Answer 1

I ended up here when I was trying to compare the unique Id of objects that could themselves be null. Found it easier to just impute the missing data first, and then do the comparison.

Guid currentId = (Object1 == null) ? Guid.Empty : Object1.Id;
Guid newId = (Object2 == null) ? Guid.Empty : Object2.Id;
If (currentId == newId)
{
    //do happyface
}
else
{
   //do sadface
}
