我有一个主要用 C# 编写的项目。我需要为这个项目的 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点。
我想做的是能够将#include内容（如错误文件）直接放入 C/C++ 项目中。我在 C# 中对它们进行了如下定义，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:
/// 00 - Success (non-fatal) 0x00
/// 01 - Informational 0x01
/// 10 - Warning 0x02
/// 11 - Error 0x03
///
/// Error Code Base - is the starting point of all Project Errors, and is set at 0xA4 (8 Bits).
///
/// Error Class - is the error class, or API "Module" that caused the error (12 bits).
///
/// Code - the unique error code (10 bits). (0 - 1,023 (0x3FF)).
/// </summary>
private static readonly int ERR_SHIFT = 0x1E;
private static readonly int BASE_SHIFT = 0x16;
private static readonly int CLASS_SHIFT = 0x06;

private static readonly int PROJECT_SEV_WARN = 0x02;

我意识到我可以在 Enums 中添加其他东西，但是我的目标是也能够使用 C++ 编译器编译这个源代码。（上面的示例中缺少一些函数，即ProjectErrCode()从 API 调用时构建错误代码 OTF 的最终整数值的函数。）
我正在构建评论中看到的错误常量，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、将它传递给 UI 等。
如果我只有 5 或 10 个错误代码，这将不是问题。但我有超过 100 个，真的不想维护一个包含重复信息的 .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。
我怎样才能#define获得单个源文件，以便 C# 编译器可以编译它，就像 C/++ 编译器一样？我可以简单地#include "ProjectErrors.cs"- 文件名在那里不是问题。我开始认为我可以通过#define'ing 之类的东西来做到这一点，using System;但几乎被挂在那里。
