Deep-copy on Activity instance

For deep cloning (copy) objects there is a many ways. One good document for cloning is here http://www.csharp411.com/c-object-clone-wars/ . The document shows six different ways to clone objects.

In our architecture we can’t use memorystreams for serializing and deserializing objects because some classes are part of the WCF datacontract and Serializable attribute on classes will force DatacontractSerializer to act way that we don’t want.

For cloning objects we use reflection technic. We create new object based on source object type and then loop all object field and copy source objects values to the copy. Everything works fine until we implement System.Lazy variables in our classes. How to deep c

I made a login for her but I can't test whether it works or not because no matter how much I "disconnect" in the Copy Web Site page of VWD 2010, reconnecting to the same site always logs in as my superuser account without prompting me for a login again.

How do I test is the account it set up correctly before having her try to upload to it?    I want to force the login to remote site dialog to pop up again to test her account.

Any ideas?

 I have read the data of a excle file and captured the data into the dataset to a datatable, now that data is to be inserted into a SQL Server table using bulk copy option. I am using -

 public bool BulkEnterData(DataTable dt, string tblName)

        con.Open();
        bulk.WriteToServer(dt);
        con.Close();
