 {
     batch.Delete(SliceBuilder.Begin(prefix).Add(key));
 }

Example #2

 {
     batch.Put(SliceBuilder.Begin(prefix).Add(key), value.ToArray());
 }

Example #3

 {
     return(db.Get(options, SliceBuilder.Begin(prefix).Add(key)).ToArray().AsSerializable <T>());
 }

Example #4

 public static T Get <T>(this DB db, ReadOptions options, byte prefix, ISerializable key, Func <Slice, T> resultSelector)
 {
     return(resultSelector(db.Get(options, SliceBuilder.Begin(prefix).Add(key))));
 }
