.NET xsd导入器创建不可序列化的类

invalidoperationexception xsd xml .net c#

我正在使用.NET XSD.EXE 导入程序从XSD文件集合生成C#类。当我试图将其中一个类序列化为XML时,它失败了( ),当我深入研究时,我发现其中一个创建的类似乎是错误的。

<xsd:complexType name="SuccessType">
    <xsd:annotation>
        <xsd:documentation>Indicates in a response message that a request was successfully processed.</xsd:documentation>
    </xsd:annotation>
    <xsd:sequence>
        <xsd:element ref="Warnings" minOccurs="0" maxOccurs="unbounded"/>
    </xsd:sequence>
</xsd:complexType>
<!-- .. snip .. -->
<xsd:element name="Warnings" type="WarningsType">
    <xsd:annotation>
        <xsd:documentation>The processing status of a business message and any related warnings or informational messages.</xsd:documentation>
    </xsd:annotation>
</xsd:element>
<!-- .. snip .. -->
<xsd:complexType name="WarningsType">
    <xsd:annotation>
        <xsd:documentation>A collection of warnings generated by the successful processing of a business message.</xsd:documentation>
    </xsd:annotation>
    <xsd:sequence>
        <xsd:element ref="Warning" maxOccurs="unbounded"/>
    </xsd:sequence>
</xsd:complexType>
<!-- .. snip .. -->
<xsd:element name="Warning" type="WarningType">
    <xsd:annotation>
        <xsd:documentation>Defines details of a warning that occurred during message processing.</xsd:documentation>
    </xsd:annotation>
</xsd:element>
<!-- .. snip .. -->
<xsd:complexType name="WarningType">
    <xsd:annotation>
        <xsd:documentation>Defines details of a warning that occurred during message processing.</xsd:documentation>
    </xsd:annotation>
    <xsd:sequence>
        <xsd:element ref="WarningCategory"/>
        <xsd:element ref="WarningCode"/>
        <xsd:element ref="WarningShortMessage"/>
        <xsd:element ref="WarningMessage"/>
    </xsd:sequence>
</xsd:complexType>

下面是由此生成的C代码:

public partial class SuccessType
{

    private WarningType[][] warningsField;

    /// <remarks/>
    [System.Xml.Serialization.XmlArrayItemAttribute("Warning", typeof(WarningType), IsNullable = false)]
    public WarningType[][] Warnings
    {
        get
        {
            return this.warningsField;
        }
        set
        {
            this.warningsField = value;
        }
    }
}

它使 Warnings 数组的数组 WarningType InvalidOperationException

错误CS0030:无法将类型“WarningType[]”转换为“WarningType”
错误CS0029:无法将类型“WarningType”隐式转换为“WarningType[]”
错误CS0029:无法将类型“WarningType”隐式转换为“WarningType[]”

但是如果我从 WarningType[][] WarningType[] 然后它就可以序列化了。

我想要什么 是正确序列化为XML并根据XSD进行验证的C代码。现在这个锯齿状数组似乎是错误的,因为如果我删除它,它就会生成XML。

XsdObjbectGen 工具,也来自Microsoft,但从.NET SDK独立和带外发布。

事实上,在重读你的问题时,你从未说过你真正想要的。是否希望SuccessType包含数组数组?

是吗 警告类型 ? 您提供的代码片段之间存在一些分歧。

public class WarningType
{
    public String oof;
}


public partial class SuccessType
{
    private WarningType[][] warningsField;

    /// <remarks/>
    [System.Xml.Serialization.XmlArrayItemAttribute("Warning", typeof(WarningType[]), IsNullable = false)]
    public WarningType[][] Warnings
    {
        get
        {
            return this.warningsField;
        }
        set
        {
            this.warningsField = value;
        }
    }
}

... 然后将其编译成DLL。然后,我在该DLL上运行了xsd.exe,并生成了以下xsd:

<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="WarningType" nillable="true" type="WarningType" />
  <xs:complexType name="WarningType">
    <xs:sequence>
      <xs:element minOccurs="0" maxOccurs="1" name="oof" type="xs:string" />
    </xs:sequence>
  </xs:complexType>
  <xs:element name="SuccessType" nillable="true" type="SuccessType" />
  <xs:complexType name="SuccessType">
    <xs:sequence>
      <xs:element minOccurs="0" maxOccurs="1" name="Warnings" type="ArrayOfArrayOfWarningType" />
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="ArrayOfArrayOfWarningType">
    <xs:sequence>
      <xs:element minOccurs="0" maxOccurs="unbounded" name="Warning" type="ArrayOfWarningType" />
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="ArrayOfWarningType">
    <xs:sequence>
      <xs:element minOccurs="0" maxOccurs="unbounded" name="WarningType" nillable="true" type="WarningType" />
    </xs:sequence>
  </xs:complexType>
</xs:schema>

…而且是往返的。如果在该模式上运行xsd.exe,则会得到一个封装数组的类型。
