Hi guys,

I have a little trouble throwing an exception in a remoting service. I'm
calling a xyz Method passing by ref a DataTable, in the remoting service
method I'm processing this DataTable using a for{} statement, and when I find
an error then a set one custom column named errorStatus on TRUE and then I
throw the exception. If I run this service local (not remoting mode) the
DataTable passing by ref keep the status, but If I run it using remoting the
DataTable don't keep the status.

Check the follow code:

class remotingservice : MarshallbyRef
{
remotingservice()
{}

public void xyz(ref DataTable data)
{
for (int i = 0; i < data.Count; i++)
{
data.Index = 0;
// some internal process to know if the row has an error
if (errorexist)
{
data.OnError = True;
break;
}
}

if (data.OnError)
{
throw new System.Exception("");
}
}
}

Derive your exception class from ApplicationException, IDisposable, and
ISerializable interfaces, apply proper methods, i.e. protected
Dispose(true)/ and Dispose. and for ISerializable, GetDataObject, and a
protected ctor. In short, use custom serialization of your exception class,
and try throwing it from remoting object, you will get the DataTable object.

Good Luck.
