尝试以下：using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Xml;using System.Xml.Serialization;namespace ConsoleApplication110{&nbsp; &nbsp; class Program&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; const string INPUT_FILENAME = @"c:\temp\test.xml";&nbsp; &nbsp; &nbsp; &nbsp; const string OUTPUT_FILENAME = @"c:\temp\test1.xml";&nbsp; &nbsp; &nbsp; &nbsp; static void Main(string[] args)&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; XmlReader reader = XmlReader.Create(INPUT_FILENAME);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; XmlSerializer serializer = new XmlSerializer(typeof(XML));&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; XML xml = (XML)serializer.Deserialize(reader);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; XmlWriterSettings settings = new XmlWriterSettings();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; settings.Indent = true;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; XmlWriter writer = XmlWriter.Create(OUTPUT_FILENAME, settings);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; serializer.Serialize(writer, xml);&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; public class XML&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; public int StatusCode { get; set; }&nbsp; &nbsp; &nbsp; &nbsp; public string Warnings { get; set; }&nbsp; &nbsp; &nbsp; &nbsp; [XmlArray("Errors")]&nbsp; &nbsp; &nbsp; &nbsp; [XmlArrayItem("Error")]&nbsp; &nbsp; &nbsp; &nbsp; public List<string> errors { get; set; }&nbsp; &nbsp; }}

Answer 2

你的班级应该是这样的：public class ErrorClass{&nbsp; &nbsp; struct Error&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; public String message;&nbsp; &nbsp; }&nbsp; &nbsp; struct Warning&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; public String message;&nbsp; &nbsp; }&nbsp; &nbsp; int StatusCode;&nbsp; &nbsp; List<Error> Errors;&nbsp; &nbsp; List<Warning> Warnings;}错误和警告结构可能包含更多您发布的示例中未使用的项目。

要基于 XML 创建类，请将 xml 复制到剪贴板，然后在 Visual Studio 2017 中，选择菜单选项：编辑/选择性粘贴/将 XML 粘贴为类。
