How do you get the @@identity for the record just inserted?

Example code: (Not working yet)

static public UInt32 AddVertex3d(Vertex3d newVertex3d)
{
UInt32 Vertex3dId = 0;

IDbConnection myConnection = DBFactory.CreateConnection();
myConnection.Open();
try
{
IDbCommand myCommand = myConnection.CreateCommand();
myCommand.CommandText = "INSERT INTO tagml_vertex3d SET MeshNodeId=?id,X=?x,Y=?y,Z=?z,LastModified=sysdate()";
IDbDataParameter p = myCommand.CreateParameter();
p.ParameterName = "?id";
p.Value = newVertex3d.MeshNodeId;
AddDbTypeToParameter(myCommand, p);
p = myCommand.CreateParameter();
p.ParameterName = "?x";
p.Value = newVertex3d.X;
AddDbTypeToParameter(myCommand, p);
p = myCommand.CreateParameter();
p.ParameterName = "?y";
p.Value = newVertex3d.Y;
AddDbTypeToParameter(myCommand, p);
p = myCommand.CreateParameter();
p.ParameterName = "?z";
p.Value = newVertex3d.Z;
AddDbTypeToParameter(myCommand, p);

p = myCommand.CreateParameter();
p.ParameterName = "?Identity";
p.DbType = DbType.UInt32;
p.Direction = ParameterDirection.Output;
AddDbTypeToParameter(myCommand, p);

myCommand.ExecuteNonQuery();
Vertex3dId = (UInt32)myCommand.Parameters["?Identity"];
}
catch(Exception e)
{
myConnection.Close();
throw e;
}
myConnection.Close();
return Vertex3dId;
}
