Use of long count in LINQ

Long count is similar to count as it works same but the only difference between them is that long count returns a 64 bit integer.

For Example:-

int[] marks = new int[] { 23, 45, 78, 90, 56, 89, 10, 32 };

      Int64 res = marks.LongCount(x => x % 2 == 0);

                        OR

long res_long = marks.LongCount(x => x % 2 == 0);

       Response.Write(res_long);

The output of this code will be 5.
