Or operator in Conditional attribute in C#

Question

In C# we can differentiate code execution depending on the type of build. By default we have Debug and Release types defined.
We can do it using the #if directive:

#if DEBUG     public void Foo()     { ... } #endif 

But we can also use Conditional attribute:

[Conditional("DEBUG")] public void Foo() { ... } 

The second solution is even claimed to be more maintainable (see: Effective C# by Bill Wagner).

My question is - how can I use the Conditional attribute with many build configurations? Is it possible to somehow use the or operator? I ask because I want some Foo method to be executed both in, for example, the DEBUG and BAR build configurations. What then?

Answer 1

You can use multiple comma separated conditional attributes like

[Conditional("DEBUG"), Conditional("BAR")] 

and it will be exactly your desired behaviour - they will be logically ORed together.

See MSDN for reference.
