当元素是MS类时,如何控制.NET XML序列化/反序列化以排除元素,因此我无法编辑源代码以添加XMLIgnore等

您可以使用 XmlAttributeOverrides 类来指定您不拥有的类的属性:

var overrides = new XmlAttributeOverrides();
overrides.Add(
    typeof(ScriptingOptions),
    "Encoding",
    new XmlAttributes { XmlIgnore = true });
var serializer = new XmlSerializer(typeof(ScriptingOptions), overrides);

但一般来说,使用特定的类来处理序列化通常更方便,正如a-h所建议的那样,因为它给了您更多的灵活性。

有时最简单的解决方案是最好的,但您可以创建一个DTO,其中只包含您想要的财产,使用AutoMapper从源映射到目标(CreateMap不是线程安全的),并从那里直接反序列化为源类型:

using AutoMapper;
using Microsoft.SqlServer.Management.Smo;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Serialization;
namespace SerializationTest
{
    class Program
    {
        static void Main(string[] args)
        {
            Mapper.CreateMap<ScriptingOptions, ScriptingOptionsDto>();

            var so = new ScriptingOptions();
            var soDto = Mapper.Map<ScriptingOptionsDto>(so); 
            string xml = Serialize(soDto);

            Console.WriteLine(xml); 
            Console.ReadLine(); 

            so = Deserialize(xml);

            Console.WriteLine(so.ToString());
            Console.ReadLine();
        }

        public static string Serialize(ScriptingOptionsDto dto)
        {
            var serializer = new XmlSerializer(dto.GetType()); 
            var ms = new MemoryStream();
            serializer.Serialize(ms, dto); 
            return Encoding.UTF8.GetString(ms.ToArray());
        }

        public static ScriptingOptions Deserialize(string xml)
        {
            var serializer = new XmlSerializer(typeof(ScriptingOptions));
            return serializer.Deserialize(new MemoryStream(UnicodeEncoding.UTF8.GetBytes(xml))) as ScriptingOptions;
        }
    }
