Solution 1

It would be a matter of seconds to point out your bug if we has a code sample from you. This is a very simple thing: the compiler detected that there is some code which never can be executed. For example, if you write some lines of code right after after return, it's apparent that none of those lines can be executed.

Look properly at your code and you will see it. If you still cannot see it (I cannot imagine why would you fail to see it), them create a code sample (very short) and post it (use "Improve question").

As SA already pointed out details of it,
if (ds.Tables[0].Rows.Count <= 0)
{
return true;
}
else
{
return false;
}
return false;//error on this line

in above code, you have put a return after an if-else, where based on whatever condition, one return of if or else would get executed. Thus, the last return is redundant and of no use - unreachable!

Yes, but how can I upvote your solution when you put it here? :)

Upvote SA's answer. He already replied correctly based on whatever was shared, I just added code reference once it was shared by OP.

:)

I already did. I figured that was your reason for posting your comment under his solution.
