 Well, actually my stupid implementation do this

pigeon% cat b.rb
#!./ruby
class Customer
   def initialize
      @_Customerid = 123
      @_city = 'abc'
      @_secret = 'hush hush'
   end
end

c = Customer.new

class Object
  def class_local_variables_to_hash
    result = {}
    self.class_local_variables(type).each do |var|
        result[var] = eval var
    end
    result
  end
end

hash = c.class_local_variables_to_hash
hash.each_key {|key| puts "\"#{key}\" => \"#{hash[key]}\""}
pigeon% 

pigeon% b.rb
"@_city" => ""
"@_secret" => ""
"@_Customerid" => ""
pigeon% 

 #eval is evaluated with current_class == rb_cObject
