sorry i didn't understand....can you please show me code for only 1 or 2 questions ???

Even if you are not using a database, you should have a repository of correct answers (for instance an array). What's the problem in matching the user's answer against such repository?

Solution 1

Assuming that you are using a database to store results, and you stroe a "1" for correct and "0" for incorrect:

SQL

SELECT SUM(Answers) FROM MyTable WHERE UserId=666

Will do it for user 666.

If that isn't how you store things, then there is a huge range of things you could be doing - and we can't tell what they are!

thanks for replying me but i am not using any database in this

OriginalGriff 26-Mar-14 4:15am

Then what are you using to store information?

Member 10682729 26-Mar-14 4:18am

i want to store only the score of user....not the answers of the questions

OriginalGriff 26-Mar-14 4:46am

Yes - but the users score is the sum of the correct answers - and you either have to store the correct / incorrect answers *somewhere*, or store the "running total" - otherwise you don;t know.
Remember, I can't see your screen, or access you HDD, so I only get whet you tell me.
So what are you doing when an user answers a question?

Your code has (at least) two problems:

It is incorrect.
it it clumsy.

You may simple do something like:

C#

RadioButton [] rbGood =
 { RadioButton2, RadioButton6, RadioButton10, RadioButton14, RadioButton18,
   RadioButton22, RadioButton26, RadioButton30, RadioButton34, RadioButton38 };
int total = 0;
for (int k=0; k<9; k++)
{
  if (rbGood[k].Checked) total++;
}
Label1.Visible = true;
Label1.Text = total.ToString();
