Exposing Business Objects

Question

I want to pass a BO that is a collection of different other BO's into my WS, i am using C# to create my WS how do i expose my BO's to Clients?

Answer 1

Hi,

You will have to convert the custom collection to a list or array so that they can be serialized. Look at this example

http://www.devx.com/dotnet/Article/30158/0/page/4

It uses generics to return a list of custom Business Objects.

Answer 2

You need to serialize the BO objects to String and then u can get the string in Windows forms or ASP.NET web forms by de-serializing back to object...


Code to Serilize
------------------
        public string XMLSerialize(object pObject)
        {
            try
            {
                XmlSerializer objXMLSerilize = new XmlSerializer(pObject.GetType());
                using (StringWriter stream = new StringWriter())
                {
                    objXMLSerilize.Serialize(stream, pObject); stream.Flush();
                    return stream.ToString();
                }
            }
            catch (InvalidOperationException ex)
            {
                throw ex;
            }
        }

Code to De-Serialize
------------------------
        public object XMLDeSerialize(object pObject, string strXMLString)
        {
            try
            {
                XmlSerializer objXMLSerilize = new XmlSerializer(pObject.GetType());
                using (StringReader stream = new StringReader(strXMLString))
                {
                    return objXMLSerilize.Deserialize(stream);
                }
            }
            catch (InvalidOperationException ex)
            {
                throw new InvalidOperationException("Failed to create object from xml string", ex);
            }
        }


How to Serialize using the above code
--------------------------------------------
fg_sXMLString = XMLSerialize(objFOTrnCodeMstList);


How to De-Serialize using the above code
--------------------------------------------
objFOTrnCodeMstList = (List<FOTrnCodeMst>)XMLDeSerialize(objFOTrnCodeMstList, fg_sXMLString);

in the above code objFOTrnCodeMstList is my BO object, and fg_sXMLString is the serialized string



sounds simple.... just try it out :-)
