Check for items inside a Entity Framework linq result

Question

I am trying to check to see if any results were returned from an entity framework query before acting upon it, I'm trying to use the code :-

var shoppingCartSessions = from c in context.ShoppingCartSessions where c.UserId == gUserID select c;
if (shoppingCartSessions.First() != null)
{
}

However I get the error

Sequence contains no elements

I have checked around stack and found that I can replace .First with .FirstOrDefault however I wanted to check if this is the correct way to be checking for existence of elements. Is there a better way rather than trying to fetch the item and then checking it?

Answer 1

Use Any():

var shoppingCartSessions = from c in context.ShoppingCartSessions 
                           where c.UserId == gUserID 
                           select c;
if (shoppingCartSessions.Any())
{
     //not empty
}
