Ryan,

Generally, the string indexer is slower than the integer indexer, as the
string indexer requires a lookup for the column to get the value from.

I believe that the indexer with the DataColumn is the fastest though.

Hi,
In my own experience DataRow[int] is the fastest. Not sure this is 100%
true though.
But unless you have a big number of columns I do not think that it will be
cause a significant change.
