It does no work with a number that is not in the array

Process is terminated due to StackOverflowException when selecting value 15.

to correct

Console.WriteLine(“index no. is {0}”, b.searching(iArray, 0, iArray.Length , number));

The boundaries are wrong when making the recursive call. Please see the correct one below.

else if (value < array[middle])

{

return searching(array, first, middle – 1, value); }

else

{

return searching(array, middle + 1, last, value); }

why do you need middle parameter? could you explain this?
