soap and c#, problem with generated code

[nomoremisterfatguy]

I generated a class file by using wsdl.exe and a wsdl-file.
Now one of the top elements in the result xml is optional which gives me some problems. In the generated code I have this:

 
[System.Web.Services.Protocols.SoapRpcMethodAttribute("", RequestNamespace="http://abc/xyz", ResponseNamespace="http://abc/xyz")]
[return: System.Xml.Serialization.SoapElementAttribute("wmInternalErrorMsg")]
public string wsInnehavFond(__innehavFondInput[] innehavFondInput, out string Status, out string KundID, out __innehavFondOutput[] innehavFondOutput) {
object[] results = this.Invoke("wsInnehavFond", new object[] {
innehavFondInput}); 
Status = ((string)(results[1]));
KundID = ((string)(results[2]));
innehavFondOutput = ((__innehavFondOutput[])(results[3]));
return ((string)(results[0]));
}
 

if the "innehavFondOutput" element is missing then this method fails (exception: "Cannot assign object of type System.String to an object of type __innehavFondOutput[]."}
If the element is there, however, this works like a charm.

Any idea what I should do??
