WCF - Missing integer parameter processed as 0

Question

I am using WCF to create a SOAP Webservice, and now I am facing the following problem:

• I have an OperationContract defined that looks like this:

[OperationContract] void InsertSomeData(string version, int someId);

• When testing the service using soapUI, I realized that if I remove someId tags in the request, I get a value of 0 in my service
• Is this standard behavior? In fact, I would suggest that the service threw some kind of exception, since the parameter cannot be null.
• Can I distinguish my service between 0 as the real value that was transmitted and just the missing tags, or do I need to set all my parameters to zero in advance.

Thank you for your help.

Hacking Method:

 [OperationContract] public void InsertSomeData(MyData data){...} [DataContract] public class MyData{ [DataMember] public string version{get;set;} [DataMember(IsRequired=true)] public int someId{get;set;} }
