i trying write nice consumer api convention-based config binder in c#. configmanager.getsection(...) returns object, want return dynamic object, when cast required type invokes mapper. is there way in c#4+ create dynamic class can handle invocation upon having explicit cast applied it? e.g. myconfig config = (myconfig)configurationmanager.getsection("some/section"); in case, dynamic object configurationmanager invoked cast perform config magic (i have solved bit) yes, dynamicobject has override-able tryconvert . when dynamicobject subclass cast (or implicitly converted assignment) tryconvert invoked, , can dynamic details invocation binder parameter before returning result. the binder.type property provides type object must converted. example, statement (string)sampleobject in c# (ctype(sampleobject, type) in visual basic), sampleobject instance of class derived dynamicobject class, binder.type returns string type. binder.explicit prope...

what equivalent in objective-c of .net's system.text.encoding.unicode ? have tried: nsunicodestringencoding nsutf8stringencoding nsutf16stringencoding none of above converted text correctly. according http://msdn.microsoft.com/de-de/library/system.text.encoding.unicode.aspx , system.text.encoding.unicode little-endian utf-16 encoding. equivalent nsstring encoding nsutf16littleendianstringencoding . nsutf16stringencoding almost same, prepends unicode byte-order marker (bom) ff fe data. (and strictly speaking, not documented nsutf16stringencoding uses little-endian, explicit nsutf16littleendianstringencoding should used anyway.)
