Explanation:

In the above program, we created the RandomEvens class that contains the Main() method.

IEnumerable Numbers = ((ParallelQuery)ParallelEnumerable.Range(1,50))
.Where(num => num % 2 == 0)
.Select(val => val);

Here we created integer numbers collection of IEnumerable type. Here we generated random even numbers. Then we printed the random even numbers between the range 1 to 50 on the console screen.
