c# 模型到 protobuf 消息（gRPC 項目）

Question

我可以找到很多關於如何從 protobuf 消息生成 C# 模型的資源（它甚至內置在 Grpc.AspNetCore 包中），但反之則不行。

我創建了一個類似於此的 blazor webassembly 客戶端/服務器項目： https://github.com/stevejgordon/gRPCBasicSample/

我有一個域層，其中包含許多用於應用程序的 C# 模型。 我想將這些模型轉換為消息回復“查看模型”，而不是全部寫在手中（我什至不確定 c# 和 protobuf 之間的正確轉換）

示例：C# Model：

    /// <summary>
    /// The area.
    /// </summary>
    public class Area
    {
        /// <summary>
        /// Initializes a new instance of the <see cref="Area"/> class.
        /// </summary>
        /// <param name="name">Name of the region.</param>
        /// <param name="areaType">What type of area is the region.</param>
        /// <param name="numberOfSupplies">number of supplies the region has.</param>
        /// <param name="numberOfMusterCrows">number of crowns the region has.</param>
        public Area(string name, AreaType areaType, int numberOfSupplies, int numberOfMusterCrows)
        {
            this.Name = name;
            this.AreaType = areaType;
            this.NumberOfSupplies = numberOfSupplies;
            this.NumberOfMusterCrowns = numberOfMusterCrows;
            this.CurrentArmy = new Collection<Unit>();
            this.AdjacentAreas = new Collection<Area>();
        }

        /// <summary>
        /// Gets the name of the region.
        /// </summary>
        public string Name { get; }

        /// <summary>
        /// Gets or sets which house the area is controlled by.
        /// </summary>
        public House ControlledBy { get; set; }

        /// <summary>
        /// Gets the type of area the region is.
        /// </summary>
        public AreaType AreaType { get; }

        /// <summary>
        /// Gets the adjacent regions the region has.
        /// </summary>
        public IEnumerable<Area> AdjacentAreas { get; internal set; }

        /// <summary>
        /// Gets the number of supplies (barrels) the region has.
        /// </summary>
        public int NumberOfSupplies { get; }

        /// <summary>
        /// Gets the number of crowns the region has.
        /// </summary>
        public int NumberOfMusterCrowns { get; }

        /// <summary>
        /// Gets or sets a value indicating whether the region is occupied by troops.
        /// </summary>
        public bool IsOccupied { get; set; }

        /// <summary>
        /// Gets a value indicating whether the region has a stronghold.
        /// </summary>
        public bool HasStronghold { get; }

        /// <summary>
        /// Gets a value indicating whether the region has a castle.
        /// </summary>
        public bool HasCastle { get; }

        /// <summary>
        /// Gets or sets the current armies occupying the region.
        /// </summary>
        public ICollection<Unit> CurrentArmy { get; set; }

        /// <summary>
        /// Gets or sets the current order token placed.
        /// </summary>
        public OrderToken? PlacedOrderToken { get; set; }
    }

應該變成這樣的東西（簡化）：

message AreaReply {
  string name = 1;
  enum AreaType {
    Land = 0;
    Water = 1;
  }
  AreaType areaType = 4;
  House controlledBy = 5;
}
message House {
    google.protobuf.StringValue name = 1;
}

真的沒有這樣的發電機嗎？ :)

謝謝

在 class 定義之上使用此注釋：

[ProtoContract(ImplicitFields = ImplicitFields.AllPublic)]
