Is there a way to list down the linked assembly names?

I want to list down the assembly names which are linked to my .exe. As I see in c#, we have an API which does the thing I want i.e. "Assembly.GetReferencedAssemblies" Description: Gets the AssemblyName objects for all the assemblies referenced by this assembly.

Similar to C#, can we get the list of libraries in c++.

It would be great if anyone could give me an advice.

Here you go. Open VS and create a new Win32 console application
Copy and paste below code. Run it.

#include "stdafx.h"
#include <windows.h>
#include <tchar.h>
#include <psapi.h>
#include <vector>
#include <iostream>
#include <string>

int PrintModules(DWORD processID)
{
    std::vector<HMODULE> modules;
    HANDLE process;
    DWORD bytesNeeded;

    std::cout << "Process ID:" << processID << std::endl;
    process = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, processID);
    if(NULL == process)
        return 1;

    EnumProcessModulesEx(process, nullptr, 0, &bytesNeeded, LIST_MODULES_ALL);
    modules.resize(bytesNeeded / sizeof(HMODULE));
    if(EnumProcessModulesEx(process, modules.data(), modules.size() * sizeof(HMODULE), &bytesNeeded, LIST_MODULES_ALL))
    {
        for(auto handle : modules)
        {
            std::vector<char> moduleName(1024, 0);
            auto newSize = GetModuleFileNameEx(process, handle, moduleName.data(), moduleName.size());
            moduleName.resize(newSize);
            std::cout << "\t" << moduleName.data() << std::endl;
        }
    }
    CloseHandle(process);
    return 0;
}

int main()
{
    PrintModules(GetCurrentProcessId());
    return 0;
}

You should get something like

Process ID:9348
C:\Path\Visual Studio 2015\Projects\ConsoleApplication5\Debug\ConsoleApplication5.exe
C:\WINDOWS\SYSTEM32\ntdll.dll
C:\WINDOWS\System32\KERNEL32.DLL
C:\WINDOWS\System32\KERNELBASE.dll
C:\WINDOWS\SYSTEM32\MSVCP140D.dll
C:\WINDOWS\SYSTEM32\VCRUNTIME140D.dll
C:\WINDOWS\SYSTEM32\ucrtbased.dll

Now add new Win32 DLL to the solution. Link your console application with it. Call any method from new library in your main. Something like this.

int main()
{
    auto res = fnMyLibrary();
    PrintModules(GetCurrentProcessId());
    return 0;
}

Rerun you program. You should get something like this

Process ID:9348
C:\Path\Visual Studio 2015\Projects\ConsoleApplication5\Debug\ConsoleApplication5.exe
C:\WINDOWS\SYSTEM32\ntdll.dll
C:\WINDOWS\System32\KERNEL32.DLL
C:\WINDOWS\System32\KERNELBASE.dll
C:\Path\Visual Studio 2015\Projects\ConsoleApplication5\Debug\MyLibrary.dll
C:\WINDOWS\SYSTEM32\MSVCP140D.dll
C:\WINDOWS\SYSTEM32\VCRUNTIME140D.dll
C:\WINDOWS\SYSTEM32\ucrtbased.dll

The whole solution is here
