How do you fetch the questions - all at a time or one by one from the db?

Use Random clase to generate the random question numbers and then use this number to fetch question. The below sample generated 10 random number between 1-20. In your case use the count of questions available in qustion bank.

C#

Random r = new Random();
for (int i = 0; i < 10; i++)
{
      int x= r.Next(20);
      MessageBox.Show( x.ToString());
}
