难道一个C＃预处理工具存在？

问题描述

有谁知道一个实用程序来预处理的不编译它的C＃源文件，以类似的方式在GCC使用-E标志？我试图使用GCC - 它成功处理＃如果指令，但它扼流圈上的任何＃地区指令...

Does anyone know of a utility to preprocess a C# source file without compiling it, in a similar fashion to using the -E flag in GCC? I tried using GCC - it successfully processes #if directives, but it chokes on any #region directives...

在理想情况下，我希望能够通过一个cs文件运行该工具，以消除任何＃如果计算结果为假，并任选能够标志是否删除/触动意见，＃地区，的#pragma 指令等。

Ideally, I'd like to be able to run the tool over a .cs file to remove any #if blocks that evaluate to false, and optionally be able to flag whether to remove/leave intact comments, #region, #pragma directives etc.

要放在这一背景下，我希望能够将公布一些源代码，这是一个（多）更大的项目的一部分，同时除去部分那些只对大项目有关。举个例子，有一些像这样的代码块：

To put this in context, I want to be able to a publish some source code that is part of a (much) larger project, whilst removing portions that are only relevant to the larger project. As an example, there are chunks of code that look like this:

#if (SUBPROJECT)
namespace SubProject
#else
namespace CompleteProject
#endif
{
  public class SomeClass()
  {
#if (!SUBPROJECT)
    // This might call a method contained in an assembly that potentially
    // won't be available to the sub-project, or maybe a method that hooks
    // into a C library via P/Invoke...
    string result = CallSomeCleverMethod();
#else
    // This might call a method that performs a simplified version of the
    // above, but does so without the above's assembly or P/Invoke
    // dependencies...
    string result = CallSomeSimpleMethod();
#endif
  }
}

请记住我没有试图做构建在这里 - 这纯粹是有关发布只是一个更大的项目的源代码的一个子集

Please remember I'm not trying to do builds here - this is purely about publishing only a subset of a larger project's source code.

推荐答案

原来使用GNU C预处理器（CPP），直接（而非通过GCC）提供了对输出更多的控制。用这种方法，我能够处理以合适的方式将源文件...

It turns out using the GNU C preprocessor (cpp) directly (rather than via gcc) provides more control over the output. Using this, I was able to process the source files in a suitable fashion...

下面是一个例子：

cpp -C -P -DSUBPROJECT Input.cs Output.cs

我就先提供与Visual Studio做同样的事情在C / C ++编译器，但一会儿......

I tried to get the C/C++ compiler provided with Visual Studio to do something similar, but gave up after a while...
