How to check if there is an element inside a list?

Question

I need to check if there’s a status on my list.. I am passing a parameter (a state code) and the method will see in the list if that state exists...something of this kind in C#:

if (listState.Contains(s.nIDState) == estado)
{
    return true;
}

someone has an idea how to do?

Answer 1

If I understand correctly:

return listState.Any(l => l.nIDState == estado);

Any is an extension of Enumerable. It checks if there is at least one item on the list that is equal to estado, returning true, or false otherwise.

Answer 2

From what I understand you want to know if there is an element in a list in a do column like this:

return listState.FindAll(l => l.nIDState == "estado");

Findall looks for what exists inside a certain column.

It is good to find certain item returned from a database query....
