I am a junior developer, and trying to write an application to consume SOAP web service.

Using web reference, I can easily call web method of Soap web server, but the problem is that
the server return an object (UBL XML object I think). And I can access its individual elements/nodes as a XML object. But if I want output its response to a XML file/object, how could I do it? It’s probably a trivial task to output the object as a XML object, but I am not sure where to start. I’ve tried that simple call ToString() of the returned object wouldn’t work. Do I need went a level down passing http POST sent SOAP header and body and interpreting/writing response stream to get response as XML text?

This is the code I used to retrieve UBL formated XML object:

/// <summary>
/// Used by supplier to check Order
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnRequestPO_Click(object sender, EventArgs e)
{
    string t_return;
    SupplierServices supplierServices = new SupplierServices();

    LoginDetails lgDetails = new LoginDetails();
    lgDetails.UserName = "user";
    lgDetails.Password = "password";
    supplierServices.LoginDetailsValue = lgDetails;

    RequestPurchaseOrder requestPO = new RequestPurchaseOrder();
    requestPO.SupplierCode = "1234";
    try
    {
        Order returned_order = supplierServices.SupplierRequestPO(requestPO);
        if (returned_order != null)
        {
            //Simply call the ToString wouldn't work, it will return a
            //class name instead.
            t_return = returned_order.ToString();
            MessageBox.Show(t_return);
        }
        else
            MessageBox.Show("Returned order is empty!");
    }
    catch (Exception ex)
    {
        String responseFromServer = ex.Message.ToString() + " ";
        if (ex!= null)
        {
          MessageBox.Show(responseFromServer);
        }
    }

And here is the SOAP response I should get:

You can use the XmlSerializer:

public static string Serialize(object input)
{
    if (input == null)
        return null;

    System.Xml.Serialization.XmlSerializer ser = new System.Xml.Serialization.XmlSerializer(input.GetType());

    using (MemoryStream ms = new MemoryStream())
    using (StreamReader sr = new StreamReader(ms))
    {
        ser.Serialize(ms, input);
        ms.Seek(0, 0);
        return sr.ReadToEnd();
    }
}

and pass your returned_order in like so:

MessageBox.Show(Serialize(returned_order));
