Good people, I’m going through a little problem, I have an application in c++ and I have to make the output of it read by a program made in C#. would you like to know if there is any way to do that? , would you like to have a communication between them.

    Hello be welcome ! try to add some more details of your application in c++ in the statement, you can start with the code snippet , we have to understand how and made the "exit" of your program. The "output" would be text in a console application ?

  • Initially the output is done by console, but I wanted it to be otherwise, I do not have much c base++.

  • How about saving the output to a text file ( .txt ) ? so you can read in a program in C# I believe it would be the easiest way.

  • but I could make my program in c# check if there is content in that txt?

  • My real problem is this, I’m trying to develop an application that through a camera identifies the plate of a vehicle and sends this response to my program done in c#, I wanted to do everything in c# but I couldn’t find any tools to help me develop the identification part of the plate in this language, only in c++.

  • But Opencv for example is possible to integrate with C#

"i have an application in c++ and have to make the output from it be read by a program done in C#. I would like to know if it exists some way to do it?"

Yes, my suggestion is that you do the storage of the output information in a arquivo.txt.

The following examples are applications made in Console.

The first example is a c++ that creates and writes the board information into a file .txt

Program C++

#include <iostream>
#include <fstream>
using namespace std;
int main () {
  ofstream myfile;
  myfile.open ("Placa_Veiculo.txt");
  myfile << "ABC-1234";
  myfile.close();
  return 0;
}

The second will perform the reading of the text file. where so in your program c# will perform the desired treatment for plate information.

Program in C# 

static void Main(string[] args)
        {
            try
            {   // abrir arquivo de texto usando stream reader.
                using (StreamReader sr = new StreamReader(@"C:\Users\usuario_do_mal\Desktop\Pasta do meu Projeto C++\Placa_Veiculo.txt"))
                {
                    // Ler arquivo e armazenar a informação da placa
                    String Leitura_Arquivo = sr.ReadToEnd();
                    string Placa = Leitura_Arquivo;
                }
            }
            catch (Exception e)
            {
                Console.WriteLine("Erro  :");
                Console.WriteLine(e.Message);
            }
        }

Remember to use the namespace System.IO.

Obs : Note that a well simplified example, and was made to meet the need for everything that was said up to the moment.

What you need is to realize Interop between applications.
If you have the module signature in C/C++, you can use this tool which makes mounting of types interfacing automatically:
Pinvoke Interop Assistant
