Sending mail with OUTLOOK VBScript to C#

Question

I made a script in VBScript to send mails via Outlook that works pretty well. The mail's body & subject has 3 different models depending on variables entered in command windows.

I have a .bat file and a .vbs file. .bat file is made for user front view and variables registry. .vbs file is made to send the mail with the variables sent from .bat.

My project is to enhance front view with a Windows Form Application built in C#. A simple window with 3 radio buttons, a textbox and a button that will send the mail on_click, with 2 variables. var1 = would be one of the 3 models. var2 = a "real life file" number.

Here is the VBScript code :

Const ForReading = 1

Set args = WScript.Arguments

Dim ToAddress
Dim FromAddress
Dim CcAddress
Dim BccAddress
Dim MessageSubject
Dim MyTime
Dim MessageBody
Dim ol, ns, newMail
MyTime = Now

ToAddress = "ToAddress@somewhere.com"
FromAddress = "FromAddress@somewhere.com"
CcAddress = "CcAddress@somewhere.com"
BccAddress = "BccAddress@somewhere.com"
MessageSubject = args(0)
MessageBody = args(1)
Set ol = WScript.CreateObject("Outlook.Application")
Set ns = ol.getNamespace("MAPI")
Set newMail = ol.CreateItem(olMailItem)
newMail.Subject = MessageSubject
newMail.Body = MessageBody
newMail.Recipients.Add(ToAddress)
newMail.SentOnBehalfOfName = FromAddress
newMail.CC = CcAddress
newMail.BCC = BccAddress
newMail.Send

The difference with C# is that one variable is "set" with whichever RadioButton is checked and then, with a if(){} function I choose which model is sent. The other variables are set with {metroTextBox1.Text}.

Here's my C# code on SendButton Click Event :

private void flatCustButton012_Click(object sender, EventArgs e)
        {
            if (metroRadioButton1.Checked)
            {
                //HERE WILL GO THE C# CODE to SEND MAIL
                radButtonChecked = true;
                MetroFramework.MetroMessageBox.Show(this, $"Your mail has been sent successfully\nMODEL#1\nFile Nb : {metroTextBox1.Text}", "Mail sent !", MessageBoxButtons.OK);
            }

            if (metroRadioButton2.Checked)
            {
                //HERE WILL GO THE C# CODE to SEND MAIL
                radButtonChecked = true;
                MetroFramework.MetroMessageBox.Show(this, $"Your mail has been sent successfully\nMODEL#2\nFile Nb : {metroTextBox1.Text}", "Mail sent !", MessageBoxButtons.OK);
            }

            if (metroRadioButton3.Checked)
            {
                //HERE WILL GO THE C# CODE to SEND MAIL
                radButtonChecked = true;
                MetroFramework.MetroMessageBox.Show(this, $"Your mail has been sent successfully\nMODEL#3\nFile Nb : {metroTextBox1.Text}", "Mail sent !", MessageBoxButtons.OK);
            }
            metroTextBox1.Text = String.Empty;
        }

I'm not a pro coder but I know some basics and I tried to start to convert. I'm now at the point where:

• i need to call Outlook Application,

• set the ol, ns, newMail variables

• and send the email

Here is where I'm at for now :

For case MODEL#1 :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using MetroFramework.Forms;
using MetroFramework.Design;
using MetroFramework.Fonts;

namespace MyApplication
{
    public partial class Form1 : MetroFramework.Forms.MetroForm
    {
    radButtonChecked = flase;
    //here i declare all my variables ?
    string ToAdress = "ToAdress@something.com"
    string FromAddress = "FromAddress@something.com"
    string CcAddress = "CcAddress@something.com"
    string BccAddress = "BccAddress@something.com"

    //then all my other classes / events
    //public Form1() etc...
    //until i come to my SendButton_Click(event)

private void flatCustButton012_Click(object sender, EventArgs e)
            {
                if (metroRadioButton1.Checked)
                {
                    radButtonChecked = true;

                    //HERE IS THE converted CODE location
                    string MessageSubject = $"MODEL#1 Nb : {metroTextBox1.Text}";
                    string MessageBody = $"Please do MODEL#1 Nb : {metroTextBox1.Text}";
                    //
                    //REST of the convertion that i have no idea how to :
                    //Call OUTLOOK APPLICATION (=ol)
                    //getNameSpace MAPI ? (=ns)
                    //create mail item (= newMail)
                    //then all the new.Mail.Something = variables previously set with "string"
                    //and finally the newMail.Send
                    //
                    //REST OF THE IF :
                    MetroFramework.MetroMessageBox.Show(this, $"Your mail has been sent successfully\nMODEL#1\nFile Nb : {metroTextBox1.Text}", "Mail sent !", MessageBoxButtons.OK);
                }

Answer 1

Ok so here's the result working in case anyone else is wondering how to do :

My "mistake" was not casting the application properly.

In public partial class :

string ToAdress = "ToAdress@something.com";
string FromAddress = "FromAddress@something.com";
string CcAddress = "CcAddress@something.com";
string BccAddress = "BccAddress@something.com";
Outlook.Application application = new Outlook.Application();

Then in your "event trigger"

Outlook.MailItem newMail = (Outlook.MailItem)application.CreateItem(Outlook.OlItemType.olMailItem);

Right adter this line you just specify newMail.Something, where something = To/From/CC/BCC/Subject/Body etc..

And end with newMail.Send();

@BugFinder you were right, i just needed more searching and most of all testings. :p

My deep apologies if that's not StackOverflow policy to give answers/responses like this; please, of course, feel free to edit and/or close.

My goal is to help others. ;)

Thanks.
