Does protobuf-net support nullable types?

Question

Is it possible to generate nullable members in protobuf-net?

message ProtoBuf1 {
    optional Int32? databit = 1;
    optional Nullable databool          


        

Answer 1

Proto 3

Import "wrappers.proto" supports nullable values:

• string(StringValue),
• int(Int32Value),
• bool(BoolValue)
• and etc

Full list of supported types - https://docs.microsoft.com/en-us/dotnet/architecture/grpc-for-wcf-developers/protobuf-data-types#nullable-types

Example:

syntax = "proto3";
import "google/protobuf/wrappers.proto";

message ProtoPerson {
    google.protobuf.StringValue firstName = 1;
    google.protobuf.StringValue lastName = 2;
    google.protobuf.StringValue address1 = 3;
    google.protobuf.Int32Value age = 4;
}
