Webservice send to simpletype and enumeration

I have a problem that I hope has a simple answer, but I cannot for the life of me figure it out, hopefully someone out there can help me!

I am accessing the following section of a wsdl:

<s:element name="Login">
<s:element minOccurs="0" maxOccurs="1" name="sUserName" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="sUserPassword" type="s:string"/>
<s:element minOccurs="1" maxOccurs="1" name="enIdentifier" type="tns:EnLoginIdentifiers"/>
<s:simpleType name="EnLoginIdentifiers">
<s:restriction base="s:string">
<s:enumeration value="User"/>
<s:enumeration value="Manager"/>

So I make the call with:

myWS.Login("userIDgoeshere","passwordgoeshere", ???)

I am at a loss for what to put for ???, if it were a complex data type, I could use a dto to send the correct value over, but with this setup I am stumped. (And no, I can’t just change the WSDL, it’s out of my hands, unfortunately)

If anyone could give an example how to make this work I would be very grateful, and if there is any other information I can give to clarify my issue, please let me know!

Thanks in advance for any help!:flower:
