66.1 How do you persist any object in the registry

To store an object in the registry, the object should be serializable (either has a Serializable attribute attached to it or derives from ISerializable; same holds to all contained objects).

ArrayList names; // Source object; Can contain any object that is serializable

... // Fill up this arraylist

BinaryFormatter formatter = new BinaryFormatter();

MemoryStream stream1 = new MemoryStream();

formatter.Serialize(stream1, names);

RegistryKey regKey;

... // Open the key where you want to store it, with write permissions

regKey.SetValue("ValueName", stream1.ToArray());

To Read from registry:

ArrayList names; // Destination object

RegKey regKey;

... // Open the corresponding key

BinaryFormatter formatter = new BinaryFormatter();

MemoryStream stream1 = new MemoryStream();

byte[] barray1 = null;

barray1 = (byte[])regKey.GetValue("ValueName");

if(barray1 != null)

{

stream1.Write(barray1, 0, barray1.Length);

MemoryStream stream1 = new MemoryStream();

byte[] barray1 = null;

barray1 = (byte[])regKey.GetValue("ValueName");

if(barray1 != null)

{

stream1.Write(barray1, 0, barray1.Length);

stream1.Position = 0;

names = formatter.Deserialize(stream1) as ArrayList;

}
