Question

I’m using WCF to generate a SOAP Webservice and right now I’m facing the following problem:

• I have an OperationContract defined that looks like this


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

• While testing the service with soapUI I realized that if I delete the someId tags in the request I do receive the value 0 in my service
• Is this the standard behavior? Acutally I would suppose the service to throw some kind of Exception, as the parameter is not nullable.
• Can I differ in my service between 0 as real value that was passed and just missing tags, or do I have to make all of my parameters nullable in advance

Thank you for your help in advance.

The hack-it-about way:

[OperationContract]
public void InsertSomeData(MyData data){...}

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

}
