Dear All Experts,

foreach (object x_loopVariable in dt.Rows)
            {
                x = x_loopVariable;
                if (x("Selected") + 1 == x("correct"))
                {
                    marks += 1;

                }
            }

r.Items.Add(dt.Rows[ctr]["Choice1"]);

I got error near the

Thanku for valuable raplay

What error you got

You are right, description of the problem and the code are insufficient, but in this particular case... some of deductive method... elementary, Watson! -- please see my solution.

(However I prefer accurate questions, not riddles :-))

No, no, such question could no be correct. Declaration of "x" is not shown; but this is critical. It needs correct and complete error or exception report.

Of course.

Let's see: x_loopVariable is object. Assuming x = x_loopVariable compiles, x is also object, otherwise assignment compatibility would not allow compilation of this line.

In next line, there are two problems: "()" is a syntax for method call, but we already know x is object, cannot be a method. You could use "[]" instead, which would work if the type of x had an indexed property ("this"). But as x is object, it would not compile because it does not have this property. You might need a type case to some relevant run-time type of the actual object. I leave aside the problem of maintainability here.

And now, think about it: such "delicate" speculations! They are completely redundant, because you simply had to provide sufficient information. Why do you think we need to read your mind? This time I managed to do that (well, almost :-)) but next time it might not work.
