xml serialization via a memory stream

[Martin]

G'day,

I have encountered a problem with serializing a class using xml
serialization and a memory stream.
what i am attempting to do is serialize a class and the read the serialized
string into an xml document.
However when I convert the memory stream to a string the first character
should seemingly not be there.
The code below will compile in a comsole application.

take a look at the string "XmlizedString " in the debugger or even wrote out
to the console window.

any ideas why that extra charcter is there before the well formed xml.

many thanks in advance.

cheers

using System;

using System.Collections.Generic;

using System.Text;

using System.IO;

using System.Xml;

using System.Xml.Serialization;

namespace ConsoleApplication

{

public class Vehicle

{

private Vehicle()

{

}

public Vehicle(string VIN, string Make, string Model, int Year, string
Owner)

{

this.VIN = VIN;

this.Make = Make;

this.Model = Model;

this.Year = Year;

this.Owner = Owner;

}

public string VIN;

public string Make;

public string Model;

private int Year;

private string Owner;

}

class Program

{

static void Main(string[] args)

{

Vehicle vehicle = new Vehicle("VIN", "Make", "Model", 2007, "Myself");

String XmlizedString = null;

MemoryStream memoryStream = new MemoryStream();

XmlSerializer xs = new XmlSerializer(typeof(Vehicle));

XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream,
Encoding.UTF8);

xs.Serialize(xmlTextWriter, vehicle);

memoryStream = (MemoryStream)xmlTextWriter.BaseStream;

UTF8Encoding encoding = new UTF8Encoding();

XmlizedString = encoding.GetString(memoryStream.ToArray());

Console.Write(XmlizedString);//<----Look at the value in the debugger there
is a strange charcater before the opening "<"

XmlDocument xmldoc1 = new XmlDocument();

xmldoc1.LoadXml(XmlizedString);//<----------Error.

}

}

}

You don't need to use the XmlTextWriter just change the code to something
similar to this:

using (MemoryStream memoryStream = new MemoryStream())
{
XmlSerializer xs = new XmlSerializer(typeof(Vehicle));

xs.Serialize(memoryStream, vehicle);

XmlizedString =
System.Text.UTF8Encoding.UTF8.GetString(memoryStream.ToArray());
}
