calculate number of true (or false) elements in a bool array?

Question

Suppose I have an array filled with Boolean values and I want to know how many of the elements are true.

private bool[] testArray = new bool[10] { true, false, t         


        

Answer 1

You can use:

int CalculateValues(bool val)
{
    return testArray.Count(c => c == val);
}

This handles the true and false checks, based on your val parameter.
