Other than looking at row.Values[field1] which gives a string value of "
" is there any way of determining whether a value is empty? I notice that there is a singleton class called
but I cannot quite work out how to use it (or if it is of value in this case). Please can you give me a quick sample of how to do this?

The top of my code looks like this...
foreach (FieldPair field in rdtDiff.ResultsStore.Fields)    
int field1=field.OrdinalInResults1;                         
int field2=field.OrdinalInResults2;
