If you are using .Net 2.0 you can do the following:
private int _id;
public int ID
{
get { return _id; }
private set { _id = value; }
}

True, the schema will not validate without a result element since the default for
minOccurs is 1. We need to add monOccurs="0" to the result to make it optional.

Subject: Re: ResultMap with constructor injection
Just to recap, in case there's any confusion: constructor injection
seems to be working perfectly, as long as you're also doing
property/field injection on the object as well. Doing constructor
injection, alone, does not seem to be supported.
I'm not familiar with .xsd schemas, but here is the relevant resultMap
section of the SqlMap.xsd:
<xs:element name="resultMap">
<xs:complexType>
<xs:sequence>
<xs:element ref="constructor" minOccurs="0" maxOccurs="1"/>
<xs:element ref="result" maxOccurs="unbounded"/>
<xs:element ref="discriminator" minOccurs="0" maxOccurs="1"/>
<xs:element ref="subMap" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute name="id" type="xs:string" use="required"/>
<xs:attribute name="class" type="xs:string" use="required"/>
<xs:attribute name="extends" type="xs:string"/>
</xs:complexType>
</xs:element>
If the lack of constructor only injection support is only a parsing
problem, perhaps a minOccurs="0" needs to be added to the "result" element?
Cheers,
Peter
