C＃编译器指令 [英] C# Compiler Directives

问题描述

我看一些C＃代码，以及所遇到下面的语句：

I’m looking at some C# code, and have come across the following statement:

#if DEBUG
    // Do something here
#else
    // Do something else
#endif

我认为DEBUG将是一个地方定义如下：

I assumed that DEBUG would be a defined somewhere as follows:

#define DEBUG

但我无法找到这样的定义，虽然代码似乎表现得好像它被设置。正在调试一个特殊的情况，如果是这样，它是如何设置/取消？

But I’m unable to find such a definition, although the code seems to behave as though it were set. Is DEBUG a special case, and if so, how is it set / unset?

推荐答案

在该项目中，转到属性 - >建立。在一般情况下，你有一个选项有定义两个 DEBUG 和 TRACE 。

On the project, go to Properties -> Build. Under general, you have an option there for defining both DEBUG and TRACE.
