Yes I know. I want to open and execute that dll through executable file whether its cmd console, or form app, or bat file.

You can execute a function contained with the library by importing the dll. You can't "execute" a dll directly.

Not sure why you are quoting me. Calling a DLL from an existing process isn't direct execution.

As people before me told you, DLL is a library. If you want to call these, you need to know their signatures.

If you just want to call the entry point (DllMain), just importing it should work (depending on the implementation)

Can this method execute the dll aswell ?

Can you tell me how to call that dll file and execute it through windows console or windows form on load.

What's a form app?

Windows Form Application

DLLs are not executables. You have to call their functions to execute their contents.

It would look something like this. See the link above that I linked you to.

Code

[DllImport("MyDLL.dll")]
public static extern int MyFunction(int param1, int param2);

disagree

that, by definition, is an executable

that's how malware is executed directly in memory

Nope. Executables are standalone files that can be run. A DLL is not that.

[webdev77]

im not going to sit here and argue that dll doesnt have executable logic

DLLs do have logic that is executable. That's an objective fact. That does not make them an executable. They are very specifically called Dynamic Link Libraries for a reason and not executables.

we talking about using it in code so both need to be load first by their pe format and thats make dll much simple to do by api call.

what is the title of this thread?

Refer to steps 4 to 6 of the link of my first post in the thread.

    private static extern IntPtr LoadLibrary(string dllToLoad);

    public static void Main()
    {
        var dllPath = @"C:\path\to\your\dll.dll";
        var handle = LoadLibrary(dllPath);
        if (handle == IntPtr.Zero)
        {
            int errorCode = Marshal.GetLastWin32Error();
            throw new Exception($"Failed to load DLL. Error code: {errorCode}");
        }

        Console.ReadLine();

}

Since you have no clue about the DLL content, this will just load the DLL which will in turn execute the DllMain with attach params.
note that DLL you are trying to load might not even do anything at attach event or the context might be wrong and you will get an error(or not ¯\_(ツ)_/¯ ).
