c# - xsd.exe 为 XML 序列化生成奇怪的 C# 类

Question

我在 .xdr 文件中有一个 XML 模式。这是此文件的简化版本(仅作为示例):

<?xml version = "1.0" encoding = "WINDOWS-1252"?>  
<Schema name = "ANS.xdr"
xmlns = "urn:schemas-microsoft-com:xml-data"  
xmlns:dt = "urn:schemas-microsoft-com:datatypes">  
 <ElementType name = "Shipment" content = "eltOnly" order = "seq" model = "closed">  
  <element type = "TrackingNumber" minOccurs = "0" maxOccurs = "1"/>  
 </ElementType>  
 <ElementType name = "TrackingNumber" content = "textOnly" dt:type = "string" model = "closed"/>  
</Schema>  

使用 xsd.exe 将此文件转换为 XSD 格式，生成以下文件:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="ANS.xdr" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
  <xs:element name="ANS.xdr" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
    <xs:complexType>
      <xs:choice minOccurs="0" maxOccurs="unbounded">
        <xs:element name="Shipment">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="TrackingNumber" type="xs:string" minOccurs="0" />
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:choice>
    </xs:complexType>
  </xs:element>
</xs:schema>

最后，我能够通过以下方式生成用于 XML 序列化的 .cs 文件: xsd.exe/c ANS.xsd 结果:

using System.Xml.Serialization;

// 
// This source code was auto-generated by xsd, Version=2.0.50727.3038.
// 


/// <uwagi/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.3038")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)]
[System.Xml.Serialization.XmlRootAttribute("ANS.xdr", Namespace="", IsNullable=false)]
public partial class ANSxdr {

    private ANSxdrShipment[] itemsField;

    /// <uwagi/>
    [System.Xml.Serialization.XmlElementAttribute("Shipment", Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
    public ANSxdrShipment[] Items {
        get {
            return this.itemsField;
        }
        set {
            this.itemsField = value;
        }
    }
}

/// <uwagi/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.3038")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)]
public partial class ANSxdrShipment {

    private string trackingNumberField;

    /// <uwagi/>
    [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
    public string TrackingNumber {
        get {
            return this.trackingNumberField;
        }
        set {
            this.trackingNumberField = value;
        }
    }
}

问题是 xsd.exe 将架构名称的前缀添加到类名称:public partial class ANSxdrShipment 其中应该只是 Shipment .序列化后导致标签名称错误:

<?xml version="1.0" encoding="utf-8"?>
<ANSxdrShipment xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <TrackingNumber>PN-34-23414</TrackingNumber>
</ANSxdrShipment>

我可以只进行手动更正，但当有嵌入式 ElementType 时，问题似乎会集中起来。它会导致名称过长，尤其是在复杂的模式中，例如:

OpenShipmentsxdrOpenShipmentsOpenShipmentShipmentReturnNotificationDetailsReturnNotificationNotificationEMailAddress

Answer 1

你在序列化部分节点吗？如果你从根节点序列化，你应该得到

<?xml version="1.0" encoding="utf-8"?>
<ANSxdr xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <Shipment>
      <TrackingNumber>PN-34-23414</TrackingNumber>
   </Shipment>
</ANSxdr>

看起来好像您只序列化 Shipment 对象。它没有标记任何属性，所以使用类名作为元素名。虽然 ANSxdr.Items 装饰有 XmlElementAttribute，它将为您提供“Shipment”元素。
