c# – XSD的属性,用于防止XSD.exe FieldSpecified标志

我有一个xsd文件,下面有以下定义.当使用xsd.exe从xsd文件生成类时,enum attrs会获得一个额外的FieldSpecified属性,如下所示.除非设置了FieldSpecified属性,否则该值不会使用属性的值进行序列化.是否有一个额外的属性,我可以添加到xsd或一个标志,我可以使用xsd.exe始终导致值序列化？

来自xsd的示例：

<xs:simpleType name="adrLn">
  <xs:restriction base="xs:string">
    <xs:enumeration value="ST" />
    <xs:enumeration value="APTN" />
  </xs:restriction>
</xs:simpleType>

...

<xs:element name="AddressLine" minOccurs="0" maxOccurs="unbounded">
  <xs:complexType>
    <xs:attribute name="AddrLineTypCd" type="adrLn" />
  </xs:complexType>
</xs:element>

生成代码示例：

/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd","4.6.1055.0")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)]
public partial class RequestCheckIssueAddressAddressLine {

    private adrLn addrLineTypCdField;

    private bool addrLineTypCdFieldSpecified;

    /// <remarks/>
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public adrLn AddrLineTypCd {
        get {
            return this.addrLineTypCdField;
        }
        set {
            this.addrLineTypCdField = value;
        }
    }

    /// <remarks/>
    [System.Xml.Serialization.XmlIgnoreAttribute()]
    public bool AddrLineTypCdSpecified {
        get {
            return this.addrLineTypCdFieldSpecified;
        }
        set {
            this.addrLineTypCdFieldSpecified = value;
        }
    }
}

<xs:attribute name="AddrLineTypCd" type="adrLn" use="required" />
