Jeff,
Yeah, I had tried that once and got a 'cannot convert from
'System.IO.StringWriter' to 'System.IO.Stream' complaint from the
compiler. (The formatter's looking for a Stream in the first argument.)
StringWriter derices from TextWriter; how do we get Stream involved? I
originally started down that way.
thanks

Steve,
You can save yourself a couple lines of code by using the StringWriter:
public static string SoapSerialize(object o)
{
StringWriter sw = new StringWriter();
SoapFormatter formatter = new SoapFormatter();
formatter.Serialize(sw, o);
string ret = sw.ToString();
sw.Close();
return ret;
}
-jk

Thanks to all who replied to this; I took it all to heart and played
with various scenarios based on our needs (and the intent was, as Brent
stated, simply to persist the object to a database for a while and
re-hydrate it later), and decided to use the SoapFormatter.
I wrote a little wrapper class to handle the serialization for the
application; I've included the simplified code below for anyone
interested. Thanks again to everyone.
public class Serialization
{
public static string SoapSerialize(object o)
{
string results;
//Serialize the object
Stream stream=new MemoryStream();
SoapFormatter formatter=new SoapFormatter();
formatter.Serialize(stream,o);
//return the string
StreamReader sr =new StreamReader(stream);
sr.BaseStream.Seek(0, SeekOrigin.Begin);
results=sr.ReadToEnd();
sr.Close();
return results;
}
public static object SoapDeserialize(string soap)
{
object o;
Stream stream=new
MemoryStream(Encoding.UTF8.GetBytes(soap));
SoapFormatter formatter=new SoapFormatter();
o=formatter.Deserialize(stream);
stream.Close();
return o;
}
}
To use :
private void SerializeMyself()
{
string serialized=Serialization.SoapSerialize(this);
// call the UploadToDatabaseFunction(serialized);
}
private MyObjectType Deserialize()//summarized. You could make this
more flexible and generic by eliminating the //cast or passing in the
type, etc,.
{
//string serialized=GetObjectFromDatabaseFunction(some
identifier);
return (MyObjectType)
Serialization.SoapDeserialize(serialized);
}

IMO, the SoapFormatter is a better choice because it can represent all
serializable .NET types while the XML serializer is quite restricted as
to the types it supports. Especially if I correctly understood he
intends to save the string dta to a database and, I assume, rehydrate it
later on a .NET system.

Well, you are using the "Binary" formatter to write the state of your
object to the stream. But you subsequently try and read the binary data
as a string. You'd have better luck using the SoapFormatter.

Subject: [DOTNET] Object serialization to string representation
I'm trying a test function to serialize an object to a string (to
eventually upload the string to a database for storage). The object
serializes just fine to disk creating a Stream as a File.IO.
What I'm encountering is trying to serialize to a MemoryStream and
reading it back with a StreamReader; in the code below the string "test"
is always empty ("")
The "this" reference is the object itself which contains the
serialization implemetation.
What am I missing, and is there a simpler way to return the string
representation of a serialized object without writing to disk?
Stream stream = new MemoryStream();
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream,this);//this is the object
saving itself to the db.
StreamReader sr =new StreamReader(stream);
sr.BaseStream.Seek(0, SeekOrigin.Begin);
//test always shows ""
string test=sr.ReadToEnd();
stream.Close();
TIA
