How check bitArray contains any true or any false value?

Question

In C# and Vb.net,is any way without iterating by loop a bitarray to check contins any true or false value (Dotnet 2.0) ?

Answer 1

I doubt there's any way you could do it without a loop under the hood (as a BitArray can be arbitrarily long, unlike BitVector32), but if you just don't want to write it yourself:

var hasAnyTrue = input.Cast<bool>().Contains(true);
var hasAnyFalse = input.Cast<bool>().Contains(false);

Answer 2

If you are using the BitArray class from System.Collections you can use the following code to determine if anything is true.

C# version

var anyTrue = myArray.Cast<bool>().Any(x => x);

VB.Net Version

Dim anyTrue = myArray.Cast(Of Boolean)().Any(Function(x) x)
