codes as blow:

#define DEBUG_CHECK_RANGE 1;

void test()
{
int count = 0;
#ifdef DEBUG_CHECK_RANGE0 // it's not defined
int local = 0;
local++; // can't go to definition
count++; // can't go to definition
#endif
count++; //it's ok
}

The code inside the inactive preprocessor region is not compiled, so goto defintion cannot work for that case. This is currently the expected behavior.

I don't think that is reasonable, if there are hundreds macro defined inside makefile or other files which already existed in my work project... As i just want to goto the definitions defined in "#ifdef and #endif code", vscode could not support that.
depressed... is there anyway to solve it?
Tips: My source insight works well for that.

VS itself has a semi-workaround via Find All References, see #5398 .

I've filed a feature request on VS for Go to Def in inactive code: https://developercommunity.visualstudio.com/idea/1015351/enable-c-go-to-def-on-inactive-code.html
