c# optimising out some log statements

I have a couple of sections of code that are very processor intensive. I have debug statements in there for internal deployments and testing but when I deploy t开发者_JAVA百科o my customer sites I would like to do a build that doesn't have these. I currently use:

 ifIsDebugEnabled() 

to wrap the log messages but this is also taking up processor time and when I commented all the logging out the performance improved. Is there a standard way to go about this or are there other things I can do instead?

Thanks, Richard

To optimize out method calls, you can put the ConditionalAttribute on methods. Like this:

[Conditional("DEBUG")]
void SomeDebugMethod(string message) { 
    // ...
}

Calls to this method will be removed if the code is compiled in another configuration than DEBUG.

This is a cleaner looking way than using directives like #ifdef DEBUG .. #endif, if you can afford to put your Debug logic in Methods.

#if DEBUG
#endif

in your code to skip out code from the release build...

---

You could wrap your code with preprocessor directives like this:

#if DEBUG
// debug code
#endif

There's a complete list of available directives here

---

You can use conditional compilation:

#if DEBUG
// code to log here
#endif

The code will only be included in the compile if you're running DEBUG mode. You can also create your own conditional compilation directives using the project properties page.

---

You can use preprocessor directives to cause the debug mode check to happen at compile-time... so when you compile without DEBUG defined it will completely skip your debug code, causing no performance hit.

#define DEBUG
// ...
#if DEBUG
    Console.WriteLine("Debug");
#endif
