Question

How can I count elements that are equal to 0 in each array of a list?

I have a list List<byte[]> piks.
I would like to count in each byte[] how many elements are with equal to 0.

I tried a few ways:

from c in piksle_lista_tablic[84] 
where (c.Equals(0)) 
select c

or

piksle_lista_tablic[84].Count(n => n == 0)

and I always get the error Expression cannot contain lambda expressions.

For example:
piks[1] is an array containing 1156 items, and I would like to know how many specific elements are in that array.

PS: Can i use Linq in watch window?

Answer 1

Try this:

var zero_counts = piks.Select(p => p.Count(c => c == 0));

ps1. can i try use linq while debug?

Visual Studio doesn’t support lambda expressions in the watch window.

• VS debugging “quick watch” tool and lambda expressions
