Question

Is there any difference between using LinQ to filter compared to using a collections Where() method.

More specifically,

First

var numQuery = from num in numbers
               where (num % 2) == 0
               select num;

Second

var numQuery = numbers.Where(num => num % 2 == 0);

In the above query, which is better? And is there any performance consideration?

Thanks.

Answer 1

There is no difference. The first one is the Query Type LINQ. The second one is the Extension Method type. I’ll prefer the second one because it has many built-in functionalities.

“…however there is no semantic difference between method syntax and query syntax.”
