Lightstreamer .Net Standard Client 4.0.0
IUpdateInfo Interface

Implemented by Lightstreamer to provide information about an update for a subscribed item. The new and previous values for the subscribed fields are reported. 

If the table subscription configuration enables the "COMMAND logic", then the old field values are referred to the same key. 

Both names and positional information can be used to identify the specific fields, unless a SimpleTableInfo was used to describe the related table; in that case, only positional information can be used.
