James Michael Hare recently wrote a blog post about Char
static methods. He talks about using a method group to write less-wordy LINQ:
if (myString.Any(c => char.IsLower(c))) { xyzzy(); }
if (myString.Any(char.IsLower)) { xyzzy(); } // Less wordy FTW!
The equivalent in VB.NET would be:
If myString.Any(Function(c) Char.IsLower(c)) Then xyzzy()
If myString.Any(Char.IsLower) Then xyzzy() 'Compiler error
Sadly, I can't do the equivalent of C# here... the compiler tells me that Overload resolution failed because no accessible 'IsLower' accepts this number of arguments
... sadness. I thought it might be caused by me having Option Strict
on, but alas, that didn't work either.
I'm assuming method groups aren't availablet in VB.NET... Is there a similar feature available in VB.NET? Or any particular reason why this can't (won't) be done in VB.NET?
The equivalent VB code would be:
If myString.Any(AddressOf Char.IsLower) Then xyzzy()
