Debugging 64bit DLL inspector showing incorrect values

Question

I've built a 64 bit version of the OpenH264 DLL in debug mode (with no compiler optimisations) and am calling it in C# (via Unity). I'm using Visual Studio 2017 to attach to the running Unity process and debug my dll.

I can place breakpoints and step through the code, however all values for the code seem to be random (or sometimes null).

For example this is where the debugger reports NULL as the value of a pointer but is stopped on the line after a failed NULL check .

Why is this happening and what can I do to get correct values when inspecting variables?

Answer 1

可能是由于“目前，Visual Studio Tools for Unity仅支持托管DLL。它不支持调试本机代码DLL，例如用C ++编写的DLL。”

Answer 2

1 Please try to switch the Common Language Runtime Support under Configuration Properties :

2 Another potential reason is that the variable is not in the current context:

While debugging, Visual Studio will keep track of every variable in the current context
