How to get list of functions inside a DLL (managed and unmanaged)?

So I play around a DLL (UnityEditor.dll) I wanna to get a list of all functions inside of this managed DLL which are unmanaged (dll is probably composed from a native C++ (with statically compiled libaries if such were used) core and managed C++ wrapper all wrapped into one dll.) I want to get a list of all unmanaged functions inside of that Dll to for example create my own managed\unmanaged wrapper?

DLLs don't contain "functions". They contain code and entrypoints. It's not possible to tell from optimized code where transitions between functions occur unless you have a debug database.

Open the .dll file and look for the EXPORT section of this PE file using the binary PE/COFF specs available from Microsoft.

But that's an overkill, I think. Your question should be a concrete want. What exactly do you want to wrap and what do you have ? Only the binaries and no source/headers ?

The dumpbin.exe utility shipped with Visual Studio can be used to display a list of exports. For example:

dumpbin.exe /EXPORTS C:\WINDOWS\System32\Kernel32.dll

Example output:

Microsoft (R) COFF/PE Dumper Version 10.00.30319.01
Copyright (C) Microsoft Corporation.  All rights reserved.


Dump of file C:\Windows\System32\kernel32.dll

File Type: DLL

  Section contains the following exports for KERNEL32.dll
