Create Xml to string serializer
Although you are using the using statement with StringReader and StringWriter both the XmlReader and XmlWriter are implementing IDisposable as well, so the usage of it should be enclosed in a using statement too.  
Catching an exception without doing anything with it is usually bad practice. You should at least log the exception.  
Although you have named your variables and methods well, I am a little bit concerned about the info parameter because it isn't telling anything about what it is.
