I’m working with IINodes in .NET and was wondering what the equivalent to maxscript’s “$.getappdata…” and “$.setappdata…” are. I see AddAppDataChunk and GetAppDataChunk methods but I’m not sure the proper way to use them. Why do they require class/superclass IDs as arguments, and how do I go about converting a .NET string to/from a byte[]?

Nevermind…it was as simple as
public static void setNodeAppData (IINode node, String str, uint channel)
{
node.RemoveAppDataChunk(node.ClassID, node.SuperClassID, channel);
node.AddAppDataChunk(node.ClassID, node.SuperClassID, channel, Encoding.ASCII.GetBytes(str));
}
public static String getNodeAppData (IINode node, uint channel)
{
IAppDataChunk chunk = node.GetAppDataChunk(node.ClassID, node.SuperClassID, channel);
if (chunk != null && chunk.Data != null)
{
return Encoding.ASCII.GetString(chunk.Data);
}
return null;
}
