How to use C# dll in Labwindows CVI 2015

[Rahul_KL]

Hi,

I need to use a dll which is created using visual studio 2019 c# library.

I saw some discussion in the forum.  But I am not clear about it, especially in the exported function signature.  Can anyone share me an example codeset, please?

My Example C# code

using System;
// namespace declaration
namespace HelloWorld{ 
    // Class declaration
    public class program

   {

       public static void MainEntry()

       { 
           MyFunction(); 
           Console.ReadKey();
        }
    }

}

static int MyFunction()

{

Console.WriteLine("Hello World!");

return 0;

}

From the above example, I need to call the function "MainEntry()"  in my CVI application.  Can anyone help me?

Regards,

Rahul.

I use Robert Giesecke's "Unmanaged Exports," installable with Nuget.

using System;
using RGiesecke.DllExport;
// namespace declaration
namespace HelloWorld{ 
    // Class declaration
    public class program
   {
       [DllExport( "MainEntry", CallingConvention = CallingConvention.Cdecl )]
       public static void MainEntry()
       { 
           MyFunction(); 
           Console.ReadKey();
        }
    }
}

Much thanks for the replay.

Can you please key in few lines of example code which I should use in CVI for the same example provided.  In CVI side do I need to do any thing with RGiesecke.DLLExpor ?

Regards,

Rahul.
