Finally I found the way out. Process seems to be little confusing, so,
listing down the steps or the benefit of others.
1) create a class file myCOMobj.cs (you can use notepad to do that)
2) Add the Sample Code below
//
********************************************************************************************************//
using System;
using System.Text;
using System.Runtime.InteropServices;
namespace myCOMobj
{
public interface ImyCOMobj
{
string sayHello();
}
[ClassInterface(ClassInterfaceType.AutoDual)]
[Guid("2F3357F5-2AB4-4d24-81C1-B54A915CAEF0")]
public class myCOM: ImyCOMobj
{
public myCOM()
{
//
// TODO: Add constructor logic here
//
}
public string sayHello()
{
return "Hello From C#";
}
}
}
//
********************************************************************************************************//
3) Create a strong Key Name using the below command
c:\Temp>sn.exe -k MyKey.snk
* you will see the message "Key pair written to MyKey.snk" and a
file will be created
4) Compile the original .cs file to make a dll using this strong key.
Use the command below achieve this.
C:\Temp>csc /keyfile:"c:\temp\myKey.snk" /target:library myCOM.cs
*this will create a dll file named myCOM.dll in c:\temp directory
5) Convert the .dll to type using command
C:\Temp>regasm myCom.dll /tlb myCom.tlb
6) Add the assembly into GAC cache using command
C:\Temp>gacutil -i myCOM.dll
Testing of Component:
Component should be visible to any application on that machine having
ability to use COM objects. For verification you can test this using
Excel.
1) Open Excel, Press ALT+F11 -> VBA editor will open
2) Tools > References > MyCOM should be listed in the Available
resources. Select that and Click ok.
3) Insert a module (Insert > Module)
4) Type the Code Below
Sub Test()
Dim objMyCOM As myCOM.myCOM
Set objMyCOM = New myCOM.myCOM
MsgBox objMyCOM.sayHello
End Sub
*Message Box "Hello From C#" should be displayed. If Everything goes
fine.
