I need to make XMLRPC calls from my C# application and I failed to find any help with that. When I used XMLRPC from Ruby, it's that simple:
server = XMLRPC::Client.new2("http://server/api.php")
result = server.call("remote.procedure", [1, [['crit1', 'crit2', 'crit3']]])
is there any similar library for C#?
See if this library works for you
