I have a client server app that I am creating, it uses TCP and binary
formatting. I am attempting to return a list<> of objects that are of type
SampleObject across the app domain boundry. SampleObject is a custom class
that I have created, it contiains both value and refrence types. sometimes
it works and sometimes I receive the "No map for object '1311703010'. error
message.

Thanks for any help.

Hi Ricky,

Normally, this exception may occur an object was serialized or deserialize.
Can you locate the line which generate the exception? And log the object
which cause the exception. I suspect the problem is relative to the data
the application handled so that it looks "randomly".

This is the segment of code around the error.

_samplesObjectGrid.DataSource = null;

//
//If all users is checked then return for all users
//otherwise return for current user.
//
try
{
HA.IntelliSystem.ClientConnecter cConn = new
HA.IntelliSystem.ClientConnecter();
string connectedUserName = cConn.ConnectedUserName;

//DataTable sampleTable;
List<SampleObject> sampleTable;
if (_currentUserToolStripMenuItem.Checked)
sampleTable =
_SampleManagment.BrowseSamples("Owner",connectedUserName,
_sampleFilterCombo.SelectedItem.ToString(),_samplesTree.SelectedNode.Text);
else
sampleTable =
_SampleManagment.BrowseSamples(_sampleFilterCombo.SelectedItem.ToString(),
_samplesTree.SelectedNode.Text);

_samplesObjectGrid.DataSource = sampleTable;
_samlesView.DataSource = sampleTable;


}
catch (System.Runtime.Serialization.SerializationException se)
{
System.Diagnostics.Trace.WriteLineIf(true, se.Message);
throw;
}

The following line is the one that actually caused the exception.
sampleTable = _SampleManagment.BrowseSamples("Owner",connectedUserName,
_sampleFilterCombo.SelectedItem.ToString(),_samplesTree.SelectedNode.Text);

_SampleManagment is a remote object that is on the server using a TCP
channel and binary formatter.

Thank you so much for your help.

If there is anyother code that you need please let me know. I do remoting
setup through code, and i can also send you the SampleObject which is a
fairly large object with child objects.
 
Thank you for the information. Regarding the problem, I suggets you add
some debug code before following line:

sampleTable = _SampleManagment.BrowseSamples("Owner",connectedUserName,
_sampleFilterCombo.SelectedItem.ToString(),_samplesTree.SelectedNode.Text);

For example, add above line in a try-catch block and log the parameters
like: connectedUserName,
_sampleFilterCombo.SelectedItem.ToString(),_samplesTree.SelectedNode.Text
to a database when catching an exception. In this way, you may get a
sample which can make the problem reproducable.

Then we can make further research to see what is the problem.
