counting integers in a list

Question

I have a collection of integers in a list. I know I can do something like this to get a specific occurence:

List<ResultsViewModel> list = data.ToList<ResultsViewModel>();

            Response.Write(list[2].NoNotEncounterBarriersResult);

But how can I loop through and count number of instances of list[i].NoNotEncounterBarriersResult = trueand return the result as an integer?

Answer 1

Use Count

var count = list.Count(item => item.NoNotEncounterBarriersResult)

Answer 2

Use Count:

int count = list.Count(x => x.NoNotEncounterBarriersResult);

From the documentation:

Returns a number that represents how many elements in the specified sequence satisfy a condition.
