C# 定义并反序列化空类
我得到的XML数据包含一个信封。为简洁起见，我将重点介绍自定义字段，它是字段的集合 下面是类定义的一部分，它给了我一个问题：C# 定义并反序列化空类,c#,xml,deserialization,xml-deserialization,C#,Xml,Deserialization,Xml Deserialization,我得到的XML数据包含一个信封。为简洁起见，我将重点介绍自定义字段，它是字段的集合 下面是类定义的一部分，它给了我一个问题： namespace Model.DocuSignEnvelope { [XmlRoot(ElementName = "CustomFields", Namespace = "http://www.docusign.net/API/3.0")] public class CustomFields { [XmlElement(Eleme
namespace Model.DocuSignEnvelope
{
[XmlRoot(ElementName = "CustomFields", Namespace = "http://www.docusign.net/API/3.0")]
public class CustomFields
{
[XmlElement(ElementName = "CustomField", Namespace = "http://www.docusign.net/API/3.0")]
public List<CustomField> CustomField { get; set; }
}
[XmlRoot(ElementName = "CustomField", Namespace = "http://www.docusign.net/API/3.0")]
public class CustomField
{

}
}
public static class DocuSignExtensionMethods
{
public static T DeserializeXmlX<T>(this string input) where T : class
{
XmlSerializer ser = new System.Xml.Serialization.XmlSerializer(typeof(T));
using StringReader sr = new StringReader(input);
return (T)ser.Deserialize(sr);
}
}
如何告诉反序列化程序将这些字段反序列化为空列表无有效条目或包含3个空自定义字段的列表。以下代码有效：

using System.Linq;
using System.Text;
using System.Data;

{
class Program
{
const string FILENAME = @"c:\temp\test.xml";
static void Main(string[] args)
{
XmlReader reader = XmlReader.Create(FILENAME);
XmlSerializer serializer = new XmlSerializer(typeof(EnvelopeInfo));
EnvelopeInfo fields = (EnvelopeInfo)serializer.Deserialize(reader);
}
}
[XmlRoot(ElementName = "EnvelopeInfo", Namespace = "http://www.docusign.net/API/3.0")]
public class EnvelopeInfo
{
[XmlElement(ElementName = "EnvelopeStatus", Namespace = "http://www.docusign.net/API/3.0")]

}

将[XmlArrayItemElementName=CustomField，Namespace=更改为：[XmlEdlementElementName=CustomField，Namespace=属性仍然可以是一个列表，XmlArray需要一个父标记和一个子标记。XmlElement只需要一个标记。@jdweng我把它作为XmlElement使用，如果我没有弄错的话，它也有同样的问题……如果可以的话，我会检查一些。我在这里的某个地方切换到XmlArrayItem，然后再回答。我将验证它是否仍然存在问题。如果解析时使用打开/关闭标记，但如果子项为空，则很难解决问题。我还将添加反序列化部分为什么在xml没有名称空间的情况下有名称空间？@jdweng我创建代码已经有一段时间了……但据我回忆，xml是输入的，类是我开始使用的h只做了一些小的改动。实际上我相当确定基类就是从这里得到的。看起来好像你是说，不需要命名空间部分——这很好，但可能还有另一个问题：所以问题是……有两个点使用CustomFields。在一个点中，该类被定义为“列表”……在另一个点中……它是d定义为“字符串”。它被“字符串”阻塞。它被切换到“列表”并工作。有两种处理数组的方法1 EnvelopeStatus需要两个xml标记2 CustomFields需要一个xml标记。
