catch Custom SoapException

Hi programmers, I'm quite new in this blog, I have a question
concerning web services Soap Exceptions: I created a class
MySoapException derived from SoapException, I add the references both
server-side and client-side, and I tried to implement correctly
serialization, I mean, the "ability" of a class to be used through a
web services communication (that's not so correct, I hope you
understand what I mean).
Here is my class:

[Serializable]
public class MySoapException : SoapException, ISerializable
{
//private string tipoecc;

public MySoapException () : base()
{
//
// TODO: Add constructor logic here
//

}
public MySoapException (SerializationI nfo si, StreamingContex t
sc) : base(si,sc)

{

}

public string Tipoecc
{
get { return tipoecc; }
set { tipoecc = value; }
}

public override void GetObjectData(S erializationInf o si,
StreamingContex t sc)
{

base.GetObjectD ata(si, sc);

si.AddValue("Ti poecc", tipoecc);

}
}

In this way, the new Property Tipoecc shoud be understood and
deserializad correctly by the (soap) client.
The web service throw the customized SoapException in this way:

MySoapException myexc = new MySoapException ();
myexc.Tipoecc = "1";
throw myexc;

I set the value of TipoEcc = "1".
The following code is client-side:

catch (MySoapExceptio n mse)
{

//nel caso sincrono l'eccezione non è contenuta
nel campo InnerException

//la proprietà Tipoecc indica il valore custom con
cui è definita l'eccezione
string msg;
msg = mse.Message;
msg += "\nTipo eccezione: " +
mse.GetType().T oString();
//msg += "\nValore eccezione: " +
mse.Tipoecc.ToS tring();
MessageBox.Show (msg);

}

I think it should catch the custom exception, because I add the same
reference to the dll containing the implementation of the class
MySoapException .
But... it doesn't work!!!
The client catches the Exception ONLY as SoapException, and nothing
else.
I know there is another pretty way to pass custom fields or attributes
by appending a new XMLNode to the Detail property of a SoapException,
and it also works good... But I would like to know WHERE is my mistake
(or my mistakes...).
Thanks a lot.

I'm creating a Web service and a Windows Forms application to consume it. My question is about throwing a custom exception inside the WebService. Can that be done, and can the custom web service be handled in the Windows Forms app? For example, suppose in my WebService, I have the following exception class: '\\\\\ <Serializable()> _

Hi All, I have a problem in throwing custom exceptions from a webservice method. The custom exception is being converted into soapexception in the webservice client. only the custom exception message is present in the soapexception . Is there any way to get the exact custom exception instead of soapexception? Thanks in advance
