Hello,

Just hosted the DLR within an application to allow users some  
scripting functionality. Part of the functionality is that you can  
call a C# method and have a string returned. However, the string is  
always being returned as a ClrString which means methods like \<\< don’t  
work which is annoying. Having to write to\_s after every call isn’t  
great for my nice clean DSL 🙂

How can I get around this? I want my C# method to return Ruby string.

Thanks

Ben

## Monkey patch ClrString with the methods you need? Or make your C# method return MutableString if you are able to

Do you have the latest build of IronRuby?  
Non-mutable Ruby methods are implemented there on CLR strings.

I am using 0.3 build but I can grab the latest tomorrow. If that fails  
I will give MutableString strings a try - thanks for the responses 🙂
