如何使 xmlserializer 仅序列化纯 xml？

我需要获取纯 xml，而不需要<?xml version="1.0" encoding="utf-16"?>在开始时和xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"在第一个元素中XmlSerializer。我该怎么做？

把这一切放在一起 - 这对我来说非常有效：

// To Clean XML
public string SerializeToString<T>(T value)
{
    var emptyNamespaces = new XmlSerializerNamespaces(new[] { XmlQualifiedName.Empty });
    var serializer = new XmlSerializer(value.GetType());
    var settings = new XmlWriterSettings();
    settings.Indent = true;
    settings.OmitXmlDeclaration = true;

    using (var stream = new StringWriter())
    using (var writer = XmlWriter.Create(stream, settings))
    {
        serializer.Serialize(writer, value, emptyNamespaces);
        return stream.ToString();
    }
}
