Question

This webservice is almost converted form VB to C#, except I get this error shown below on the DataRow arow object when I use it in the foreach statement below to populate the Results Class with a DataSet Object… any ideas???

Error: A local variable named ‘arow’ cannot be declared in this scope because it would give a different meaning to ‘arow’, which is already used in a ‘parent or current’ scope to denote something else

Answer 1

aRow is being declared twice, once in the foreach and the other right above it. Remove DataRow aRow right above the foreach and you should be good.
