NetSerializer - A fast, simple serializer for .Net

NetSerializer is a simple and very fast serializer for .Net languages. It is the fastest serializer I have found for my use cases.

The main pros of NetSerializer are:

  • Excellent for network serialization
  • Supports classes, structs, enums, interfaces, abstract classes
  • No versioning or other extra information is serialized, only what is strictly needed
  • No type IDs for primitive types, structs or sealed classes, so less data to be sent
  • No dynamic type lookup for primitive types, structs or sealed classes, so deserialization is faster
  • No extra attributes needed (like DataContract/Member), just add the standard [Serializable]
  • Thread safe without locks
  • The data is written to the stream and read from the stream directly, without the need for temporary buffers

The simpleness of NetSerializer has a drawback which must be considered by the user: no versioning or other meta information is sent, which means that the sender and the receiver have to have the same versions of the types being serialized.

This means that it's a bad idea to save the serialized data for longer periods of time, as a version upgrade could make the data non-deserializable.

For this reason I think the best (and perhaps only) use for NetSerializer is for sending data over network, between a client and a server which have verified version compatibility when the connection is made.
