Int array contains
The following asp.net c# example code demonstrate us how can we determine whether an int array contains a specified
element/number pogrammatically at run time in an asp.net application. .Net framework's int array represent an array
of integer where each element value is an integer (Int32) number.
We can determine an element existence within a sequence by using Enumerable.Contains() method. We just need to specify the sequence (array) to locate the searched element and pass the searched element value to Contains() method to locate it in sequence.
So, we can determine whether an int array contains a specified integer number by calling Contains() method as this way IntArray.Contains(SpecifiedInteger). Contains() method return true if the specified integer number found in int array; otherwise it return 'false'.
