XSD.exe - 如何初始化从 xs:choice 创建的类型

Question

我对使用 XSD 和序列化反序列化还很陌生，我正在寻找一些关于如何初始化从 XSD 中的 xs:choice 元素创建的结果类对象的建议，这里有一些关于XSD 和 Object 类：

示例取自更大的 XSD，对象类。

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>

XSD.exe 创建对象类：

[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.33440")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]

public partial class exportDesignCommissionCustomerMaincontact

    private object[] faxofficeField;

    private object[] emailprivateField;

    private object[] emailofficeField;

    private object[] websiteField;


    [System.Xml.Serialization.XmlElementAttribute("company", typeof(exportDesignCommissionCustomerMaincontactCompany))]
    [System.Xml.Serialization.XmlElementAttribute("person", typeof(exportDesignCommissionCustomerMaincontactPerson))]
    public object Item

        get
        {
            return this.itemField;
        }
        set
        {
            this.itemField = value;
        }
    }


    [System.Xml.Serialization.XmlElementAttribute("phone-private")]
    public object[] phoneprivate
    {
        get
        {
            return this.phoneprivateField;
        }
        set
        {
            this.phoneprivateField = value;
        }
    }


    [System.Xml.Serialization.XmlElementAttribute("phone-office")]
    public object[] phoneoffice
    {
        get
        {
            return this.phoneofficeField;
        }
        set
        {
            this.phoneofficeField = value;
        }
    }


    [System.Xml.Serialization.XmlElementAttribute("fax-private")]
    public object[] faxprivate
    {
        get
        {
            return this.faxprivateField;
        }
        set
        {
            this.faxprivateField = value;
        }
    }


    [System.Xml.Serialization.XmlElementAttribute("fax-office")]
    public object[] faxoffice
    {
        get
        {
            return this.faxofficeField;
        }
        set
        {
            this.faxofficeField = value;
        }
    }


    [System.Xml.Serialization.XmlElementAttribute("e-mail-private")]
    public object[] emailprivate
    {
        get
        {
            return this.emailprivateField;
        }
        set
        {
            this.emailprivateField = value;
        }
    }


    [System.Xml.Serialization.XmlElementAttribute("e-mail-office")]
    public object[] emailoffice
    {
        get
        {
            return this.emailofficeField;
        }
        set
        {
            this.emailofficeField = value;
        }
    }


    [System.Xml.Serialization.XmlElementAttribute("website")]
    public object[] website
    {
        get
        {
            return this.websiteField;
        }
        set
        {
            this.websiteField = value;
        }
    }
}

我卡住的地方是我如何初始化“Maincontact”元素及其子元素，到目前为止，我已经完成了初始化类的工作：

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
            }
        }
    },
};

这可能是相当基本的，但我看不出这种初始化将如何基于条件选择来反映 XSD 选择。谁能指出我正确的方向？

再次感谢您阅读本文 :)

从xsd 生成代码的所有工具都不是完美的，对于复杂的 xsd，您需要自己添加一些代码。我建议您使用xsd2code，因为它具有可定制性。
