你写的代码，，，如下，，但写不下去了

ivate Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim stream As New MemoryStream
        Dim xmlseting As New XmlWriterSettings
        xmlseting.Encoding = Encoding.UTF8
        xmlseting.ConformanceLevel = ConformanceLevel.Document
        xmlseting.Indent = True
        Dim Xmldoc As XmlWriter = XmlWriter.Create(stream, xmlseting)

        Xmldoc.WriteStartDocument(False)
        Xmldoc.WriteStartElement("epp", "urn:iana:xml:ns:epp-1.0")
        Xmldoc.WriteAttributeString("xmlns", "xsi", "", "http://www.w3.org/2001/XMLSchema-instance")
        Xmldoc.WriteAttributeString("xmlns", "schemaLocation", "", "urn:iana:xml:ns:epp-1.0 epp-1.0.xsd")

        Xmldoc.WriteStartElement("command")
        Xmldoc.WriteStartElement("create")
        Xmldoc.WriteAttributeString("xmlns", "domain", "", "1")
        Xmldoc.WriteStartElement("create", "1")
        '  Xmldoc.WriteAttributeString("xmlns", "domain", "", "urn:iana:xml:ns:domain-1.0")
        Xmldoc.WriteAttributeString("xsi", "schemaLocation", "", "urn:iana:xml:ns:domain-1.0 domain-1.0.xsd")


        Xmldoc.WriteEndElement()
        Xmldoc.WriteEndElement()
        Xmldoc.WriteEndElement()
        Xmldoc.WriteEndElement()

        Xmldoc.Flush()
        MsgBox(Encoding.UTF8.GetString(stream.ToArray()))

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);
XmlTextWriter writer = new XmlTextWriter("baojingshezhi.xml", null);
writer.Formatting = Formatting.Indented;
doc.Save(writer);

[Quote=引用 2 楼 upc_xiaowei 的回复:]
XmlDocument doc = new XmlDocument();
doc.LoadXml(str);
XmlTextWriter writer = new XmlTextWriter("baojingshezhi.xml", null);
writer.Formatting = Formatting.Indented;
doc.Save(writer);

这个办法不行，，，，一定要在内存中直接生成
