I am getting an unhandled exception on a webservice as listed below
and my quesiton is

How do I trap it to find where it's coming from since it seems to be outside
of the my code.

Thx in advance
Mekim

An unhandled exception of type
'System.Runtime.Serialization.SerializationException' occurred in Unknown
Module.

PublicKeyToken=b03f5f7f11d50a3a is not marked as serializable

Hi,

It looks to me like someone has not tested their exception logic, and the
exception they are trying to throw is not compatible with the exception
mechanism.

To track this down, you need to be able to get to the source for the
service - so if this is not under your control I would imagine the best you
can do is to work with the party who does and treat this like a bug in a
vendors application.

Best of luck

Hi Dan,

that's the confusing part...It's my project...my source code

The error happens within the soap call mechinism

Hi Mekim,

No, the error is the the result of a bug in your code - 99.999 percent
certain. WIthout knowing what class you are trying to serialize (in your
service code) it's really hard to say where the bug is occurring.

Try placing a break point in your service code, load the project in VS and
then click debug/start, and then call the service from your test client.
Step thru the service method a line at a time and note what line it is on
where it raises an exception. The line it does this on is very likely to
contain the mistake.

Serializing a type that isn't serializable often occurs when you have
assumed that any class in the .NET Framework can readily be serialized out
to XML. There are very FEW framework classes that serialize with good
effect outside of the core data types.

I hope this helps

are you trying to Serialized (i.e. tranferring the exception across the
wire) if so then you mignt want to check out the advanced serialization
mechanism for Exception using XML friendly base64 , bear in mind this is
strictly for .net client and WS, so it's not interop friedly

[Serializable]
public class MySoapException
{

    [XmlIgnore]
    public Exception Exception;
    public MySoapException()
    {
        //Required by XML serialization
    }

    public MySoapException(Exception Exception)
    {
        this.Exception = Exception;
    }
        public string ExeptionDetail{
        get{
            MemoryStream ms = new MemoryStream();
            BinaryFormatter bf = new BinaryFormatter();
            bf.Serialize(ms, this.Exception);
            ms.Close();
            return Convert.ToBase64String(ms.ToArray());
        }
        set{
            MemoryStream ms = new MemoryStream(
                Convert.FromBase64String(value));
            BinaryFormatter bf = new BinaryFormatter();
            this.Exception = (Exception)bf.Deserialize(ms);
            ms.Close();
        }
    }
        public MySoapException(string ExeptionDetail){
        this.ExeptionDetail = ExeptionDetail;
    }
}
