Poco2Proto

Convert simple C# POCO classes into .proto message definitions for gRPC, automatically.
This library is designed to be lightweight, simple, and dependency-free and ideal for quickly generating Protobuf message contracts from your existing models.

✨ Features

  • Converts public C# class properties into .proto message fields
  • Supports string, numeric types, bool, byte[]
  • Supports List<T> and arrays (repeated fields)
  • Supports nullable types (int?, bool?, etc.)
  • Converts property names to snake_case
  • Maps DateTime to string (simple & practical)
  • Zero external dependencies

📦 Installation

NuGet Package Manager


Install-Package Poco2Proto

.NET CLI


dotnet add package Poco2Proto

🚀 Usage Example

C# Class

public class UserProfile
{
    public string FullName { get; set; }
    public int? Age { get; set; }
    public bool IsActive { get; set; }
    public List<string> Roles { get; set; }
    public string[] Tags { get; set; }
}

Generate .proto

using Poco2Proto;

string proto = Poco2Proto.GenerateProto<UserProfile>();
Console.WriteLine(proto);
// Or save to file
File.WriteAllText("UserProfile.proto", proto);

✅ Example Output

syntax = "proto3";
package YourNamespace;

message UserProfile {
  string full_name = 1;
  int32 age = 2;
  bool is_active = 3;
  repeated string roles = 4;
  repeated string tags = 5;
}

You can now place this .proto file in your gRPC project and compile it with protoc.

🔍 Notes & Limitations

This package is intentionally simple and works best when:

  • Your classes are pure POCO DTOs
  • No complex inheritance or polymorphism is needed
  • You generate .proto definitions as a starting point and refine manually if needed

Future enhancements may include:

  • Recursive nested message generation
  • Enum support
  • Custom type mappings
