Save a Queue object to the Registry

Hello,
Is it possible to save a System.Collection.Queue object to the Registy?

Im trying the below code to save a Queue containing most Recent file name to the registry in the REG Binary format. Cant seem to get it work.

public static void saveRecentFile(string strFilePath)

try

//Open Key;

RegistryKey key = Registry.CurrentUser.OpenSubKey(strBaseKey, true);

//If Key does not exist then create it

if (key == null)

Registry.CurrentUser.CreateSubKey(strBaseKey);

Queue arrMRU = (Queue)key.GetValue("MRU");

if (arrMRU == null)

arrMRU = new Queue(intMaxMRUFileCount);

else

if (arrMRU.Count == intMaxMRUFileCount)

key.SetValue("MRU",arrMRU,RegistryValueKind.Binary);

catch (Exception e)

MessageBox.Show(e.Message);
