XSD.exe - How to initialize a type created from xs:choice

问题

I'm fairly new to working with XSD's and serialization de-serialization, I'm looking for some advice on how to initialise the resulting class object created from a xs:choice element in the XSD, to start here's some info on the XSD and Object class:

Examples taken from a larger XSD, object class.

XSD:

<xs:element name="main-contact">
    <xs:complexType>
        <xs:sequence>
            <xs:choice>
                <xs:element name="person">
                    <xs:complexType>
                        <xs:group ref="person"/>
                    </xs:complexType>
                </xs:element>
                <xs:element name="company">
                    <xs:complexType>
                        <xs:group ref="company"/>
                    </xs:complexType>
                </xs:element>
            </xs:choice>
            <xs:group ref="contact"/>
        </xs:sequence>
    </xs:complexType>
</xs:element>

<xs:group name="person">
    <xs:sequence>
        <xs:element name="title" minOccurs="0"/>
        <xs:element name="salutation" minOccurs="0"/>
        <xs:element name="forename" minOccurs="0"/>
        <xs:element name="surname">
        </xs:element>
        <xs:element name="birthdate" type="xs:date" minOccurs="0"/>
    </xs:sequence>
</xs:group>

<xs:group name="company">
<xs:sequence>
    <xs:element name="name"/>
    <xs:element name="phone">
        <xs:simpleType>
            <xs:restriction base="xs:string">
                <xs:pattern value="[0-9]+"/>
            </xs:restriction>
        </xs:simpleType>
    </xs:element>
    <xs:element name="fax" minOccurs="0">
        <xs:simpleType>
            <xs:restriction base="xs:string">
                <xs:pattern value="[0-9]+"/>
            </xs:restriction>
        </xs:simpleType>
    </xs:element>
    <xs:element name="e-mail" minOccurs="0">
        <xs:simpleType>
            <xs:restriction base="xs:string">
                <xs:pattern value="[a-z | A-Z | 0-9 | . | -]+@[a-z | A-Z | 0-9 | . | -]+[.][a-z | A-Z | 0-9 | . | -]+"/>
            </xs:restriction>
        </xs:simpleType>
    </xs:element>
    <xs:element name="website" type="xs:string" minOccurs="0">
    </xs:element>
</xs:sequence>
</xs:group>

<xs:group name="contact">
<xs:sequence>
    <xs:element name="phone-private" minOccurs="0" maxOccurs="unbounded"/>
    <xs:element name="phone-office" minOccurs="0" maxOccurs="unbounded"/>
    <xs:element name="fax-private" minOccurs="0" maxOccurs="unbounded"/>
    <xs:element name="fax-office" minOccurs="0" maxOccurs="unbounded"/>
    <xs:element name="e-mail-private" minOccurs="0" maxOccurs="unbounded"/>
    <xs:element name="e-mail-office" minOccurs="0" maxOccurs="unbounded"/>
    <xs:element name="website" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:group>

Where I'm stuck is how exactly i can initialize the 'Maincontact' element and it's sub elements, so far I've got to this point with initializing the class:

export.design = new exportDesign
{
    commission = new exportDesignCommission
    {
        dateofcreation = DateTime.Now,
        dateoflastchange = DateTime.Now,
        customer = new exportDesignCommissionCustomer
        {
            maincontact = new exportDesignCommissionCustomerMaincontact
            {
                //Initialisation in question to go here
            }
        }
    },
};

This may be fairly basic but i can't see how this initialisation would work based on a conditional choice to reflect the XSD choice. Can anyone point me in the right direction?

Thanks and thanks again for reading this far :)

回答1:

All tools for generating code from xsd are not perfect and for complex xsd's you need to add some code by yourself. I better recommended for you to use xsd2code because of its customizability.

Look at that blog Here Simon Middlemiss answering your question.
