How do I set standard email client in Windows 7 using .NET

Question

I would like to set the standard email client in Windows 7 from .NET code, how do I do it?

setting the default email client is most likely a feature of the operating system that .NET has no access to — jbabey, May 03 '13 at 12:37
I am not going to make this an answer since I am not sure, but you may want to look into altering Registry variables for this. — dkroy, May 03 '13 at 12:37

You can find the default email program with the following Registry Key. Find it's content and mess with it:

Check the following link here at SO:

using System;
using Microsoft.Win32;

namespace RegistryTestApp
{
   class Program
   {
      static void Main(string[] args)
      {
         object mailClient = Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail", "", "none"); 
         Console.WriteLine(mailClient.ToString());
      }
   }
}

I have checked the registry key exist and its content. And the registry key class is not a mistery @AlexFilipovici. I forgot to link the post, but I'm doing it now. Thanks – Carlos Landeras May 03 '13 at 12:51

You would need to edit the following registry value. You would do something like the following with the Registry.SetValue Method.

Registry.SetValue(@"HKEY_CLASSES_ROOT\mailto\shell\open\command", "", "\"C:\\PROGRA~2\\MICROS~1\\Office14\\OUTLOOK.EXE\" -c IPM.Note /m \"%1\"");
