我是 C# 的新手。我有一个返回 xml 响应的 java REST 服务，我正在尝试使用 C# XmlSerializer 反序列化 xml 文档。下面粘贴了一个示例 xml 文档响应。

<?xml version="1.0" encoding="UTF-8"
 standalone="yes" ?>  <ns2:Document
 xmlns:ns2="http://hxps.honeywell.com/model/impl"
 xmlns:ns3="http://hxps.honeywell.com/datatypes/impl"
 type="PS">
 <docId>SamplePSDocument1</docId> 
 <fields
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:ns5="http://jaxb.dev.java.net/array"
 xsi:type="ns5:anyTypeArray">   <item
 xsi:type="ns3:scalarFieldImpl"
 key="Name">
      <value xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xsi:type="xs:string">HXPS A4</value>
 </item>   <item
 xsi:type="ns3:scalarFieldImpl"
 key="Creation Date">
       <value xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xsi:type="xs:string">20 April
 2007</value>    </item> </fields>
 <id>fb92f871-1f3d-4fa4-ba24-5ae3af0a493f</id>
 <revision>1-c75f688e212fb5341ebdbd22a3867c14</revision>

 - <version>   <majorVersionNumber>1</majorVersionNumber>
 <minorVerisonNumber>5</minorVerisonNumber>
 </version> </ns2:document>

当我将此 xml 文档反序列化为 Document 对象时，它工作正常。我的文档类粘贴在下面

[System.SerializableAttribute()]
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://hxps.honeywell.com/model/impl", TypeName = "PSDocument")]
[System.Xml.Serialization.SoapTypeAttribute(Namespace = "http://hxps.honeywell.com/model/impl", TypeName = "PSDocument")]

        {
            return this._type;
        }
        set
        {
            this._type = value;
        }
    }

    /// <summary>

        set

            if (!value)
            {
                this._type = Com.Honeywell.Hxps.Sdk.Model.DocumentType.NULL;
            }
        }
    }

        }
        set
        {
            this._description = value;
        }
    }

        }
        set
        {
            this._revision = value;
        }
    }
    /// <summary>

    [System.Xml.Serialization.XmlElementAttribute(ElementName = "id", Namespace = "")]
    [System.Xml.Serialization.SoapElementAttribute(ElementName = "id")]
    public string Id
    {
        get
        {
            return this._id;
        }
        set
        {
            this._id = value;
        }
    }
}
}

在我的主程序中，当我尝试时，我得到了一个 xmlNodes 数组

Array fields = (Array)doc.Fields;

在服务器端 java REST 服务实现中，字段实际上是一个数组列表，它将包含一个接口的三个实现的实例。（列表可能包含自定义业务对象的 ScalarFieldImpl 或 ArrayFieldImpl）。

我想使用 XmlSerializer 将此 xml 字段反序列化为 ScalarFieldImpl 或 ArrayFieldImpl。我想知道这是否可能？如果是这样，我该怎么做？

我得到了这个工作。我对我的 PSDocument 类做了一些更改。

私有对象_fields；-> 私有 ArrayList _fields；

我还更改了 get/set 方法并添加了新的元数据

[System.Xml.Serialization.XmlArray(ElementName = "fields", Namespace = "")] [System.Xml.Serialization.XmlArrayItem(ElementName="item")]

公共 ArrayList 字段 { 获取 { 返回 this._fields; } 设置 { this._fields = 值；} }

以前我的 PSDocument 类中有以下几行

[System.Xml.Serialization.XmlElementAttribute(ElementName = "fields", Namespace = "")] [System.Xml.Serialization.SoapElementAttribute(ElementName = "fields")] public object Fields { get { return this._fields; } 设置 { this._fields = 值；} }

因此，在反序列化 PSDocument 中的字段时，我得到了一个包含项目作为元素的数组列表。希望这可以帮助某人。

据我所知，使用 ootb xml (de-)serializer 是不可能的，我认为您必须编写自己的 XmlSerializer。或者尝试使用 LINQ to XML。
