Trying to get a processname but the First property does not exist

Question

The line is:

foreach (var handle in EnumerateProcessWindowHandles(
        Process.GetProcessesByName("explorer").First().Id))

But First does not exist:

Error 1 'System.Array' does not contain a definition for 'First' and no extension method 'First' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)

Answer 1

Add the reference

using System.Linq;
