Re: [Ikvm-developers] How to refer to identifiers containing a $ from C#

Hi Rüdiger, IKVM does not automatically do this conversion for various reasons (mostly because Java actively discourages the usage of $ in identifiers and if I did do an automatic conversion it would still end up looking really ugly and most people probably wouldn't like it anyway). As you found C# doesn't have a way to access these identifiers. @ only works for keywords. The only practical solution is to write Java wrappers. The map.xml approach is also not really intended for this (although you could use it to add additional methods/properties that alias the methods/fields, but there is nothing for class names).
