engine.ExecuteFile gives errors

Ruby IronRuby
1

I am using the following code to execute a Ruby file from C# but it
gives me the error:

var runtime = IronRuby.Ruby.CreateRuntime();
var engine = runtime.GetEngine(“rb”);

        engine.ExecuteFile("../../HelloWorld.rb");

And here is the error:

Unhandled Exception: Microsoft.Scripting.SyntaxErrorException: syntax

And here is the Ruby file:

class Person

def foo()
puts ‘hello world’
end

end

person = Person.new()
person.foo()

Is it possible that you’ve saved the file as UTF-8 or Unicode?

Well I just created a text file with “.rb” extension.

That is a problem because visual studio adds UTF-8 encoding to that
file.
I created one file in notepad and made a template from that file and I
use
that template to create new ruby files in visual studio.

Here’s the easiest way I know how to check:

  1. Open the file in Notepad
  2. Choose “File | Save As”
  3. Look at the value for “Encoding”. If it’s anything other than “ANSI”,
    change the encoding to ANSI, save the file and try again.

Awesome guys I got it working!

Thanks a million! :slight_smile:
