Question

I have 2 clases:

 public class products
{
    public string category;
    public string name;
    public double price;
    public string desc;
    public string version;
    public string logoURL;
    public string imgURL;
    public string prod;

    public string Category
    {
        set { categorie = value; }
        get { return category; }
    }

and:

    [Serializable()]
public  class groupProducts
{
    public products[] produse;
}

I want to XmlSerialize the groupProducts class and send the data from a server via TCP conection to a client!
I’ve tried something like:

   groupProducts gp = new groupProducts();
XmlSerializer xmlSel = new XmlSerializer(typeof(groupProducts));
TextWriter txtStream = new StreamWriter("xmlStreamFile.xml");    
xmlSel.Serialize(txtStream, gp); 
txtStream.Close();
try
{
Stream inputStream = File.OpenRead("xmlStreamFile.xml");
// declaring the size of the byte array to the length of the xmlfile
msg = new byte[inputStream.Length];
//storing the xml file in the byte array
inputStream.Read(msg, 0, (int)inputStream.Length);
//reading the byte array 
communicator[i].Send(msg);
}

but it when I Deserialize it on the client side – the XML file has some weird data in it!

Do you have any idea what could it be? What am I doing wrong?

Answer 1

1- To be safe I would use an encoding while opening StreamWriter

2- In inputStream.Read(msg, 0, (int)inputStream.Length); Read does’t guarantee that you will get inputStream.Length bytes from stream. You have to check the returned value.

3- You don’t need a temp file. Use MemoryStream

XmlSerializer xmlSel = new XmlSerializer(typeof(groupProducts));
MemoryStream m = new MemoryStream();
xmlSel.Serialize(m);
communicator[i].Send(m.ToArray());
