我需要纯XML，而不＆LT; XML版本=1.0编码=UTF-16＆GT; 开头和的xmlns：XSI =htt​​p://www.w3.org/2001/XMLSchema-instance的xmlns：XSD =htt​​p://www.w3.org/2001/XMLSchema从的XmlSerializer 第一要素。我该怎么办呢？

I need to get plain xml, without the <?xml version="1.0" encoding="utf-16"?> at the beginning and xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" in first element from XmlSerializer. How can I do it?

推荐答案

要把这一切在一起 - 这完美的作品对我来说：

To put this all together - this works perfectly for me:

    // To Clean XML
    public string SerializeToString(T value)
    {
        var emptyNamepsaces = 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, emptyNamepsaces);
            return stream.ToString();
        }
    }
