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.
