c# - creating proxy using wsdl programmatically and wsdl parsing -

i working on xml web services. client web service "client" has url of wsdl of server web service "service" @ run time. in order "client" use "service" need following thing "programmatically":

1) wsdl file on fly "service" or location on disk. 2) create proxy programmatically i.e not using wsdl.exe or add web reference. 3)invoke methods on created proxy.

is possible it? if 1 has done greatful take suggestions how accomplish.
