serialisation of classes to generate XMLDocument

[Stephen]

I need to generate input XML for another application by serialising classes
defined in an XSD document. The code below will generate the XML I require
but I need to generate this in memory rather than creating a file. I assume
I should be using System.IO.Memor yStream but can't get this to work.

' XML will be serialized to file.xml, in UTF-8, with BOM.
Dim tw As New System.Xml.XmlT extWriter( _
New System.IO.FileS tream("file.xml ",
System.IO.FileM ode.Create), _
New System.Text.UTF 8Encoding(True) )
ser.Serialize(t w, domainObj.getGM PApp)
' Finish writing the file and close it.
tw.Flush()
tw.Close()
xmlDoc.Load("fi le.xml")

how about serializing to a string?

<!--StartFragment-->
XmlSerializer s1 = new XmlSerializer(t ypeof(MyType));
System.IO.Strin gWriter sw = new System.IO.Strin gWriter();
s1.Serialize(sw , instance);
// sw.ToString() now holds the XML ...

this generates XML with encoding iof UTF-16 whch I can't load into the XML
documentthat I want to. The code that generates the file will generate the
XML with the correct encoding but what I want too be able to do is generate
this in code.

my bad...

Dim ms As New System.IO.Memor yStream()
Dim tw2 As New System.Xml.XmlT extWriter( ms, utf8 )
Try
ser.Serialize(t w2, dto1)
tw2.Flush()
ms.Seek(0, System.IO.SeekO rigin.Begin)

Dim byteArray as Byte()
byteArray= New Byte(CType(ms.L ength, Integer)){}
Dim count As Integer
count = 0

' Read the Bytes, Byte by Byte.
While(count < ms.Length)
byteArray(count ) = _
System.Convert. ToByte(ms.ReadB yte())
count += 1
End While

' Decode the Byte array into a Char array
' and write it to the console.
Dim charArray as Char()
charArray = _
New Char(utf8.GetCh arCount(byteArr ay, 0, count)){}
utf8.GetDecoder ().GetChars( byteArray, 0, count, charArray, 0)
System.Console. WriteLine(charA rray)

Finally
ms.Close()
tw2.Close()
End Try

thank U for the code below, which when I run it generates the required XML
in the charArray. However I am still having problems using this XML. What I
want to do is take this XML and use it in an XSL transformation to generate
the input XML for another application. Do you know what I need to do to load
the serialised XML into something that the transform can use?
..
..
Dim xslt As New Xml.Xsl.XslTran sform
Dim xr As Xml.XmlResolver
Dim transformXSL As [String] = "transform. xsl"
xslt.Load(trans formXSL)
writer.Formatti ng = Xml.Formatting. Indented
xslt.Transform(---- XML ----, Nothing, ---Output XM L---, Nothing)
