在 C# 和 C++ 之间共享源文件

我有一个主要用C#编写的项目。我需要为该项目的 API 的所有错误号"定义"定义一个类。我试图避免编写/更改我的许多代码生成器之一来实现这一目标。

我想做的是能够将内容（如错误删除）直接#include到 C/C++ 项目中。我在 C# 中按如下方式定义了它们，并且我没有对您将在此处看到的内容使用枚举：

using System;
namespace ProjectAPI {
[Serializable]
public sealed class ProjectError {
    public enum ProjectErrorClass {
        None            = -1,
        Undefined       = 0,
        Login,
        Store,
        Transaction,
        Heartbeat,
        Service,
        HTTPS,
        Uploader,
        Downloader,
        APICall,
        AutoUpdate,
        General
    }
    public enum ProjectErrorLevel {
        Unknown = -1,
        Success = 0,
        Informational,
        Warning,
        Critical,
    };
    /// <summary>
    /// PROJECT_ERROR_BASE - This is the base for all Project defined errors in the API.  Project Errors are defined as follows:
    ///   ProjectAPI error values are 32 bit values defined as follows:
    ///   3 3 2 2 2 2 2 2 2 2 2 2 1 1 1 1 1 1 1 1 1 1
    ///   1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0
    ///  +---+---------------+-----------------------+------------------+
    ///  |Sev|Error Code Base| Error Class           |Unique Error Code |
    ///  +---+---------------+-----------------------+------------------+
    ///  where
    ///
    ///      Sev - is the severity code of the error (2 bits), and is defined as follows:

    ///

    /// </summary>
    private static readonly int ERR_SHIFT                       = 0x1E;

我意识到还有其他东西可以放入 Enums 中，但我的目标是能够使用 C++ 编译器编译此源代码。（上面的示例中缺少一些函数，即从 API 调用时构建错误代码 OTF 的最终整数值的ProjectErrCode()。

我正在构建注释中看到的错误常量，我可以回到那个，但我宁愿编写类似的类 - 一个在 C# 中，一个在 C++ 中可以构造/解构错误代码。我的函数返回错误的严重性、错误类等。开发人员可以忽略它，记录它，将其传递给UI等。

如果我只有 5 或 10 个错误代码，这将不是问题。但是我有 100 多个，真的不想维护带有重复信息的 .cs 和 .h 文件。我可以在 .h 文件中管理它们并让 CS 代码读取它们，但这几乎与编写（修改）代码生成器一样多。

如何#define单个源文件，以便 C# 编译器可以编译它，就像 C/++ 编译器也可以编译一样？ 我可以简单地#include "ProjectErrors.cs" - 文件名不是问题。我开始认为我可以通过#define像using System;这样的东西来做到这一点，但几乎被挂在那里了。
