SoapMethod parameters

General
1

I have to reproduce this:
ws:options
ws:Option ws:Keysend_to</ws:Key> ws:ValueRECIPIENTS</ws:Value> </ws:Option>
ws:Option ws:Keyfrom_name</ws:Key> ws:ValueYour favorite dealer</ws:Value> </ws:Option>
ws:Option ws:Keyrecipients</ws:Key> ws:Valuemike@example.com</ws:Value> </ws:Option>
</ws:options>
I used the SoapMethod in this way:
dim sm As new SOAPMethod
sm.LoadWSDLFromURL(mywsdlurl)
sm.Parameter(“options”)=“send_to=RECIPIENTS”

but when i run it the option send_to is empty. Can someone help me?
