Question

There are operators in Ruby similar to “OrElse”and “AndAlso” in VB.NET?

For example in Ruby NoMethodError exception is raised when active_record is nil:

if active_record.nil? || active_record.errors.count == 0
     ...
end

In VB.net i can do:

 If active_record Is Nothing OrElse active_record.errors.count = 0
    ...
 End

That does not generate an exception because it is only checked the first expression

Answer 1

In this case there will be no exception raised (because only the first term in || will be evaluated). However you might be interested in reading about Object#try from ActiveSupport, which can be helpful when dealing with objects that can be nil.
