在.NET中序列化对象时省略所有xsi和xsd命名空间？

using System;
using System.IO;
using System.Xml;
using System.Xml.Serialization;

[XmlRoot(ElementName = "MyObject")]
public class MyObject
{
    [XmlElement(ElementName = "Property1")]
    public string Property1 { get; set; }

    [XmlElement(ElementName = "Property2")]
    public int Property2 { get; set; }
}

public class CustomXmlWriter : XmlTextWriter
{
    public CustomXmlWriter(TextWriter writer) : base(writer)
    {
    }

    public override void WriteStartAttribute(string prefix, string localName, string ns)
    {
        if (localName == "xmlns" || localName.StartsWith("xmlns:"))
        {
            return;
        }

        base.WriteStartAttribute(prefix, localName, ns);
    }
}

public class CustomXmlSerializer
{
    private readonly XmlSerializer _serializer;

    public CustomXmlSerializer(Type type)
    {
        _serializer = new XmlSerializer(type);
    }

    public string Serialize(object obj)
    {
        using var stringWriter = new StringWriter();
        using var xmlWriter = new CustomXmlWriter(stringWriter);

        _serializer.Serialize(xmlWriter, obj);

        return stringWriter.ToString();
    }
}

public class Program
{
    public static void Main()
    {
        var myObject = new MyObject
        {
            Property1 = "Value1",
            Property2 = 42
        };

        var serializer = new CustomXmlSerializer(typeof(MyObject));
        var xml = serializer.Serialize(myObject);

        Console.WriteLine(xml);
    }
}
