DLL in C# in Visual Studio

[speed780]

Hello,

I have a dll coded in delphi language which thus contains functions in delphi which I would like to use in C# under Visual Studio 2017.

I want to use for example the GENERATE function contained in test.dll.

Below is an example of C# code I made to use test.dll in delphi in C#.

namespace AppTest
{
Public class Program
{
[DllImport("test.dll", CharSet = CharSet.Ansi)]
public static extern bool GENERATE(string path);

static void Main(string[] args)
{
GENERATE(@"C:\Users");
}
}
}




But when I test this program, I get the following error:

System.DllNotFoundException: 'Unable to load DLL' test.dll ': The specified module could not be found. (Exception from HRESULT: 0x8007007E) '

How to solve this problem ?

I placed test.dll in the folder that contains the C# source files.

How C# is able to read a dll in delphi if Visual Studio does not know delphi?


Thank you for your help.
