.net - How to define a constant globally in C# (like DEBUG)

Question

I want to compile a project differently, according to a constant defined by #define, like this:

#define USE_COMPONENT_X

#if USE_COMPONENT_X
...

#endif

and I can do that in C#. But when I go to another file in the same project, this constant is not defined. Can I in some way define a constant to all the project, like DEBUG is defined so?

Answer 1

You can add the /define compiler switch.

1. Open the project's Property Pages dialog box.
2. Click the Configuration Properties folder.
3. Click the Build property page.
4. Modify the Conditional Compilation Constants property.
