Possible unintended reference comparison; to get a value comparison, cast the left hand side to type 'string'

I am surprised the original worked. Both of the others you tried should be ok and the second would be preferred. The item you are getteing from a row is an object and needs to be cast to a string or use the built in method to get a string. Then you are comparing a string to a string. Did you try to make the change and then rebuild to verify the warning goes away?
