[Ironruby-core] How to instanciate a System::String[] from IronRuby?

[Tomas Matousek]

This is the right way:

x = ['a', 'b', 'c']
System::Array[System::String].new(x.map { |s| s.to_s.to_clr_string })

This would simplify to

x = ['a', 'b', 'c']
System::Array[System::String].new(x)

As soon as we implement implicit conversions here.

Jimmy and I have discussed a to_clr_array(type) where type defaults to Object, but nothing like that exists yet.

I don't know if it's the easiest way, but this should work as a conversion:

x = ['a', 'b', 'c']
System::Array[System::String].new(x.map { |s| s.to_s.to_clr_string })

(Obviously, if you know that the elements are already Ruby strings, you can omit the "to_s".)

Hi,

while trying to call some C# code from IronRuby, I get this:

my_csharp_class_instance.call(%w(some array))

:0: can't convert Array into System::String[] (TypeError)

Is there some easy way to construct an array of System::String ? Or a conversion ?

cheers,
