格式化XML输出

本文关键字:输出 XML 格式化 | 更新日期: 2023-09-27 18:11:36

我使用这个方法将对象转换为XML:

protected XmlDocument SerializeAnObject(object obj)
{
    XmlDocument doc = new XmlDocument();
    DataContractSerializer serializer = new DataContractSerializer(obj.GetType());
    MemoryStream stream = new MemoryStream();
    try
    {
        serializer.WriteObject(stream, obj);
        stream.Position = 0;
        doc.Load(stream);
        return doc;
    }
    finally
    {
        stream.Close();
        stream.Dispose();
    }
}

最后我得到这样的东西:

<CaCT>
  <CTC i:nil="true" xmlns="http://schemas.datacontract.org/2004/07/a.b.BusinessEntities.InnerEntities" /> 
  <CTDescr xmlns="http://schemas.datacontract.org/2004/07/a.b.BusinessEntities.InnerEntities">blabla</CTDescr> 
  <CaId>464</CaId> 
  </CaCT>

如何去掉i:nil="true"xmlns="http://schemas.datacontract.org/2004/07/a.b.BusinessEntities.InnerEntities"

格式化XML输出

我个人总是发现用LINQ to XML进行手写的XML序列化效果很好。它很灵活,你可以用任何你想要的方式使它向后和向前兼容,显然你不会有任何你不想要的额外的名称空间或属性。

显然,你的类越复杂,它就越复杂,但我发现它对简单的类工作得很好。

protected string SerializeAnObject(object obj)
{
    XmlSerializerNamespaces xmlNamespaces = new XmlSerializerNamespaces();
    xmlNamespaces.Add("", "");
    XmlWriterSettings writerSettings = new XmlWriterSettings();
    writerSettings.OmitXmlDeclaration = true;
    XmlSerializer serializer = new XmlSerializer(obj.GetType());
    using (MemoryStream ms = new MemoryStream())
    {
        using (XmlWriter stream = XmlWriter.Create(ms, writerSettings))
        {
            serializer.Serialize(stream, obj, xmlNamespaces);
            return Encoding.UTF8.GetString(ms.ToArray());
        }
    }
}
