Unity uses protobuf-net for binary serialization and deserialization

Protobuf-net provides an easy-to-use data serialization scheme that serializes class instances with [Protocontract] features and supports Unity's various publishing platforms, and is highly efficient and user-friendly.

1  Public Static classSerialization2 {3      Public Static byte[] serialize<t>(T instance)4     {5         byte[] bytes;6         using(varms =NewMemoryStream ())7         {8 Serializer.serialize (MS, instance);9bytes =New byte[Ms. Position];Ten             varFullbytes =Ms. GetBuffer (); One array.copy (fullbytes, Bytes, bytes. Length); A         } -          returnbytes; -     } the  -      Public StaticT deserialize<t> (Objectobj) -     { -         byte[] bytes = (byte[]) obj; +          using(varms =NewMemoryStream (bytes)) -         { +              returnSerializer.deserialize<t>(MS); A         } at     } -}

The following is an example of a class definition that needs to be serialized.

1 [Protocontract]2  Public classExample3 {4     //PROTOBUF Requirements5     //member without [Protomember] C # attribute whose value will not be serialized6     //isrequired is optional7     //if the member is a custom class object, that is, the class is a nested class, the ordinal must be the same as the first member ordinal in a class member object8     //if all custom class members are expanded in this class, the same ordinal cannot exist9 Ten      Public intClassName {Get;Set; } One  A[Protomember (1, isrequired =true)] -      Publicdictionary<int,int> Dictionary {Get;Set; } -  the     //must have a parameterless default constructor -      PublicExample () -     { -Dictionary =Newdictionary<int,int>(); +     } -}
