svcutil and specified fields

Question

I am generating a datacontract with svcutil from a webservice.

svcutil /language:cs /noConfig /targetclientversion:Version35 
        /out:Generated\ProductService.cs http://example.com/ProductService.svc?wsdl

The fields generated looks like this:

private System.Nullable<System.DateTime> createdField;
private bool createdFieldSpecified;

How can the fields be both nullable and have a specified field?

Answer 1

it depends on the source Wsdl. I bet there is something this (not sure of the syntax):

<xsd:element name="created" type="xsd:datetime" minOccurs="0" xsd:nil="true" />

svcutil.exe use nillable to produce a Nullable<> field, and minOccurs to produce a field + specified combination.

I also bet the WSDL is not a .Net generated WSDL !
