How I can call my DLL? (C# net8)

[xMaxrayx]

so I did this simple DLL in c# net8

Code: Select all

namespace consoleDLLtest
{
    public class ClassHello
    {
            public string Method()
        {
            return "Hi, this is from DLL";
        }
    }
}

How I can use it with AHK?
I did this but it doesn't work probably because it was bad coded xd

Code: Select all

#Requires AutoHotkey v2.0
Result := DllCall("ClassLibrary1" ,"Str" , "Method" , )
MsgBox Result

I got this EROR

Error: Call to nonexistent function.

▶ 003: Result := DllCall("ClassLibrary1" ,"Str" , "Method" , )
004: MsgBox(Result)
007: testVariable := unset

The current thread will exit.

sorry I'm net at learning DLL stuff.

Just a guess... but does the method need to be static? (I know nothing about DLL structure, but have coded C#)

　Except for User32.dll, Kernel32.dll, ComCtl32.dll, and Gdi32.dll, you must not omit the DllFile.
If unsure, provide the full path of the DllFile along with the function name. For example, C:\DllDir\DLLFile.dll\Function.
For more information, please read the parameters section of the DllCall documentation.

I actually have experience creating DLLs in C++ and applying them in AHK, but I haven't tried it in C#.
Therefore, I'm unable to offer advice on creating DLLs in C#. Sorry.

IDK I didn't learn about void, static stuff yet but I did it

Code: Select all

namespace consoleDLLtest_v2
{
    public class ClassHello_v2
    {


        public static string Hi()
        {
            return "Hi, this is from DLL";
        }

        public string Goodboey()
        {
            return "good bye";
        }


    }
}

even if it was from relative link?

I see , I read that .Net DLL not same as DLL and they are callable only with Net languages but there are workaround, and I found some stuff are only work with old Net Framwork (only windows) and not with current .Net (cross-patform).

I will try re-search more.

Recent versions of .NET have their own hosting API which differs too much from the old one for the old scripts to work.

If you can create a .dll which can be called from C (i.e. a dll with unmanaged exports), you can call it with DllCall. C++ can mix managed and unmanaged code in older .NET Framework versions, so I assume it can be done in .NET 8 as well. I don't think it can be done in C#, but I haven't tried and I very rarely touch C#.

I assume you can create COM components with .NET 8. A properly registered component can be instantiated with ComObject.
