Add values of a List object in Single line C#

Question

Am having a list object. i need to add the values in the object in a single line of code without using foreach or for loop. Is it possible using the linq query??

For eg: am having a list object userCount of length 2. I need to find the TotalManagerCount by adding the ManagerCount values in the list.

public class UserCount
{
public int ManagerCount {get; set;}
public int EngineerCount {get; set;}
}

List<UserCount> userCount = new List<UserCount>();

int TotalManagerCount = ??
int TotalEngineerCount = ??

Thanks in advance

Dinesh.

Answer 1

Use LINQ Sum function:

int TotalManagerCount = userCount.Sum(x=>x.ManagerCount);
int TotalEngineerCount = userCount.Sum(x=>x.EngineerCount);

Answer 2

Use Sum function of Linq

int TotalManagerCount = userCount.Sum(item => item.ManagerCount);
int TotalEngineerCount = userCount.Sum(item => item.EngineerCount);
