.net - 序列化对象时，在.Net中设置StandAlone = Yes

Question

在下面的代码中，我要将XML设置为“standalone = yes”，我该怎么做？

Dim settings As New Xml.XmlWriterSettings
settings.Encoding = encoding

Using stream As New IO.MemoryStream, xtWriter As Xml.XmlWriter = _
    Xml.XmlWriter.Create(stream, settings)
    serializer.Serialize(xtWriter, obj)
    Return encoding.GetString(stream.ToArray())
End Using

例如，我有这个:

<?xml version="1.0" encoding="utf-8"?>

但是我想要这个:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>

如果要执行此操作，则需要使用 WriteProcessingInstruction 方法并手动将其写出。

    Using stream As New IO.MemoryStream, xtWriter As Xml.XmlWriter = Xml.XmlWriter.Create(stream, settings)
        xtWriter.WriteProcessingInstruction("xml", "version=""1.0"" encoding=""UTF-8"" standalone=""yes""")
        serializer.Serialize(xtWriter, obj)
        Return encoding.GetString(stream.ToArray())
    End Using
