问题描述

如何注入C# 预处理器指令通过反射到接口?

How to inject C# Preprocessor Directives to an interface by Reflection ?

示例:
我想将 #if SILVERLIGHT 注入任何 WCF 服务合同接口.

Example :
I want to inject #if SILVERLIGHT to any WCF service contract interface.

推荐答案

简短的回答:你不能.
稍微长一点的答案:你的问题一开始就没有意义.

Short answer: you can't.
Slightly longer answer: you question doesn't even make sense in the first place.

预处理器指令在编译之前进行处理.该处理的结果是新的、修改过的源代码.然后编译该源代码.

Preprocessor directives are processed before compilation. The result of that processing is the new, modified, source code. That source code then gets compiled.

例如，如果编译时没有定义SILVERLIGHT符号，那么#if SiLVERLIGHT和#endif 将被编译器完全忽略，就好像它根本不存在一样.

For example, if the SILVERLIGHT symbol is not defined at the time of compilation, then the whole code between #if SiLVERLIGHT and #endif will be completely ignored by the compiler as if it wasn't even there.
