I need a punycode converter for Silverlight. For WPF have such an opportunity in the standard libraries. I need a ready-made library or code of functions (punycode encoding and decoding) {C#, Silverlight}.
回答1:
I am not sure if Silverlight has access to this namespace but take a look at these IdnMapping fuunctions which are built into the .net framework.
