We
use many aggregate functions like sum, count, average, min, and max. In LINQ we
can use this function in the following manner:-
SUM
If
we want to perform sum aggregate function then we will implement the following
queries:-
Sum with array
int[] marks
= new int[] { 23, 45, 78, 90, 56, 89, 10, 32 };
//simple sum without condition
int res =
marks.Sum();
//sum with condition
int
res_with_where = marks.Where(cond => cond > 50).Sum();
Response.Write("Sum without condition= " + res + "<br/>");
Response.Write("Sum with condition="+ res_with_where+"<br/>");
Output of this code as follows:-
