Newbie question. I have the following snippet of C# code that writes the contents of "SearchResponse" to a file. How can I get the contents into a string variable instead?

//XMLize the Manifest object to disk
FileStream fsSearchResponse = new FileStream(System.Windows.Forms.Application.StartupPath + "/xmlresponse.xml", FileMode.Create);
XmlSerializer xmlizer = new XmlSerializer(typeof(SearchResponse));

//serialize the manifest object
xmlizer.Serialize(fsSearchResponse, iw.SearchResponse);

fsSearchResponse.Close();

TIA
Mike
