J'utilise Visual Studio 201 (.NET 4). J'ai besoin de créer un objet COM (en C #) et je n'ai aucune idée de comment commencer (quel type de projet utiliser, etc.)
OK j'ai trouvé la solution et je vais l'écrire ici pour le bien commun.
using System.Runtime.InteropServices;
Au fichiervous pouvez maintenant utiliser votre objet COM en utilisant son ProgID.
exemple: le code C #:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
namespace Launcher
{
[InterfaceType(ComInterfaceType.InterfaceIsDual), Guid("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX")]
public interface ILauncher
{
void launch();
}
[ClassInterface(ClassInterfaceType.None), Guid("YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYY"), ProgId("Launcher.Launcher")]
public class Launcher : ILauncher
{
private string path = null;
public void launch()
{
Console.WriteLine("I launch scripts for a living.");
}
}
}
et VB utilisant le COM:
set obj = createObject("PSLauncher.PSLauncher") obj.launch()
et la sortie sera:
Je lance des scripts pour vivre
Étapes de création
Register = vsdrpCOM
MainWindow Vous pouvez créer un formulaire normal, voici pré-généré.
public partial class MainWindow : Form
{
public MainWindow()
{
InitializeComponent();
}

/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

Vous pouvez utiliser un projet de bibliothèque de classes. Déclarez un type avec des méthodes qui seront exposées en tant qu'objet COM.
Assurez-vous que l'assemblage a été rendu COM-visible:
Et enfin l'enregistrer en utilisant regasm.exe :
regasm.exe /codebase mylib.dll
À présent, l'assembly est exposé en tant qu'objet COM et le type que vous avez déclaré peut être utilisé par tout client qui prend en charge COM.
