You can take a look at the SQLException class -- and check for the contents of the exception's message if it contains what you now see in your inner exception..Something like this:

try
{
    //your code here
}
catch (SQLException ex)
{
    if (ex.Message.Contains("Cannot insert duplicate key in obj...."))
    {
        //your code here
    }
}
