Envoi de courrier électronique via Outlook 2010 via C #

J'essaie d'envoyer un email depuis l'intérieur de mon application console C #. J'ai ajouté les références et les déclarations d'utilisation, mais il semble que je n'ai pas ajouté tout ce dont j'ai besoin. C’est la première fois que j’essaie de faire cela, alors j’imagine que j’ai oublié quelque chose.

J'ai reçu cet extrait de code sur le site MSDN http://msdn.Microsoft.com/en-us/library/vstudio/ms269113(v=vs.100).aspx

ScreenShot of code from VS2010 showing the build errors

Voici le code avec lequel je rencontre des problèmes dans VS 2010

using System;
using System.Configuration;
using System.IO;
using System.Net;
using System.Net.Mail;
using System.Runtime.InteropServices;
using Outlook = Microsoft.Office.Interop.Outlook;
using Office = Microsoft.Office.Core;

namespace FileOrganizer
{
    class Program
    {
        private void CreateMailItem()
        {
            //Outlook.MailItem mailItem = (Outlook.MailItem)
            // this.Application.CreateItem(Outlook.OlItemType.olMailItem);
            Outlook.Application app = new Outlook.Application();
            Outlook.MailItem mailItem = app.CreateItem(Outlook.OlItemType.olMailItem);
            mailItem.Subject = "This is the subject";
            mailItem.To = "[email protected]";
            mailItem.Body = "This is the message.";
            mailItem.Attachments.Add(logPath);//logPath is a string holding path to the log.txt file
            mailItem.Importance = Outlook.OlImportance.olImportanceHigh;
            mailItem.Display(false);
        }
    }
}

remplacer la ligne

Outlook.MailItem mailItem = (Outlook.MailItem)
this.Application.CreateItem(Outlook.OlItemType.olMailItem);

avec

Microsoft.Office.Interop.Outlook.Application app = new Microsoft.Office.Interop.Outlook.Application();
Microsoft.Office.Interop.Outlook.MailItem mailItem = app.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);

J'espère que cela t'aides,

Voici comment envoyer un courrier électronique via Microsoft Office Outlook. Dans mon cas, j'utilisais Office 2010, mais je suppose que cela devrait fonctionner avec les versions les plus récentes.

L'exemple de vote supérieur ci-dessus affiche simplement le message. Il ne l'envoie pas. De plus, il ne compile pas.

Donc, vous devez d’abord ajouter ces références à votre projet .NET:

 enter image description here

Comme je l'ai dit dans mon commentaire à son op:

Vous devrez ajouter les références suivantes: (1) À partir de l'onglet .NET, ajoutez Microsoft.Office.Tools.Outlook pour l'exécution v.4.0. *, Puis à nouveau (2) depuis l'onglet .NET, ajoutez Microsoft.Office.Interop.Outlook pour la version 14.0.0.0 dans mon cas, et (3) objet COM Bibliothèque d'objets Microsoft Office 12.0 pour Microsoft.Office.Core.

Alors voici le code pour envoyer des emails:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.Net;
using System.Configuration;
using System.IO;
using System.Net.Mail;
using System.Runtime.InteropServices;
using Outlook = Microsoft.Office.Interop.Outlook;
using Office = Microsoft.Office.Core;

public enum BodyType
{
    PlainText,
    RTF,
    HTML
}

    //....

    public static bool sendEmailViaOutlook(string sFromAddress, string sToAddress, string sCc, string sSubject, string sBody, BodyType bodyType, List<string> arrAttachments = null, string sBcc = null)
    {
        //Send email via Office Outlook 2010
        //'sFromAddress' = email address sending from (ex: "[email protected]") -- this account must exist in Outlook. Only one email address is allowed!
        //'sToAddress' = email address sending to. Can be multiple. In that case separate with semicolons or commas. (ex: "[email protected]", or "[email protected]; [email protected]")
        //'sCc' = email address sending to as Carbon Copy option. Can be multiple. In that case separate with semicolons or commas. (ex: "[email protected]", or "[email protected]; [email protected]")
        //'sSubject' = email subject as plain text
        //'sBody' = email body. Type of data depends on 'bodyType'
        //'bodyType' = type of text in 'sBody': plain text, HTML or RTF
        //'arrAttachments' = if not null, must be a list of absolute file paths to attach to the email
        //'sBcc' = single email address to use as a Blind Carbon Copy, or null not to use
        //RETURN:
        //      = true if success
        bool bRes = false;

        try
        {
            //Get Outlook COM objects
            Outlook.Application app = new Outlook.Application();
            Outlook.MailItem newMail = (Outlook.MailItem)app.CreateItem(Outlook.OlItemType.olMailItem);

            //Parse 'sToAddress'
            if (!string.IsNullOrWhiteSpace(sToAddress))

                foreach (string strAddr in arrAddTos)
                {
                    if (!string.IsNullOrWhiteSpace(strAddr) &&
                        strAddr.IndexOf('@') != -1)
                    {
                        newMail.Recipients.Add(strAddr.Trim());
                    }
                    else
                        throw new Exception("Bad to-address: " + sToAddress);
                }
            }
            else
                throw new Exception("Must specify to-address");

            //Parse 'sCc'
            if (!string.IsNullOrWhiteSpace(sCc))
            {
                string[] arrAddTos = sCc.Split(new char[] { ';', ',' });
                foreach (string strAddr in arrAddTos)
                {
                    if (!string.IsNullOrWhiteSpace(strAddr) &&
                        strAddr.IndexOf('@') != -1)
                    {
                        newMail.Recipients.Add(strAddr.Trim());
                    }
                    else
                        throw new Exception("Bad CC-address: " + sCc);
                }
            }

            //Is BCC empty?
            if (!string.IsNullOrWhiteSpace(sBcc))
            {
                newMail.BCC = sBcc.Trim();
            }

            //Resolve all recepients
            if (!newMail.Recipients.ResolveAll())
            {
                throw new Exception("Failed to resolve all recipients: " + sToAddress + ";" + sCc);
            }


            //Set type of message
            switch (bodyType)
            {
                case BodyType.HTML:
                    newMail.HTMLBody = sBody;
                    break;
                case BodyType.RTF:
                    newMail.RTFBody = sBody;
                    break;
                case BodyType.PlainText:
                    newMail.Body = sBody;
                    break;
                default:
                    throw new Exception("Bad email body type: " + bodyType);
            }


            if (arrAttachments != null)
            {
                //Add attachments
                foreach (string strPath in arrAttachments)
                {
                    if (File.Exists(strPath))
                    {
                        newMail.Attachments.Add(strPath);
                    }
                    else
                        throw new Exception("Attachment file is not found: \"" + strPath + "\"");
                }
            }

            //Add subject
            if(!string.IsNullOrWhiteSpace(sSubject))
                newMail.Subject = sSubject;

            Outlook.Accounts accounts = app.Session.Accounts;
            Outlook.Account acc = null;

            //Look for our account in the Outlook
            foreach (Outlook.Account account in accounts)
            {
                if (account.SmtpAddress.Equals(sFromAddress, StringComparison.CurrentCultureIgnoreCase))
                {
                    //Use it
                    acc = account;
                    break;
                }
            }

            //Did we get the account
            if (acc != null)
            {
                //Use this account to send the e-mail. 
                newMail.SendUsingAccount = acc;

                //And send it
                ((Outlook._MailItem)newMail).Send();

                //Done
                bRes = true;
            }
            else
            {
                throw new Exception("Account does not exist in Outlook: " + sFromAddress);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("ERROR: Failed to send mail: " + ex.Message);
        }

        return bRes;
    }

Et voici comment vous l'utiliseriez:

List<string> arrAttachFiles = new List<string>() { @"C:\Users\User\Desktop\Picture.png" };

bool bRes = sendEmailViaOutlook("[email protected]",
    "[email protected], [email protected]", null,
    "Test email from script - " + DateTime.Now.ToString(),
    "My message body - " + DateTime.Now.ToString(),
    BodyType.PlainText,
    arrAttachFiles,
    null);
