这是您可以通过 Microsoft Office Outlook 发送电子邮件的方式。就我而言，我使用的是 Office 2010，但我想它应该适用于较新的版本。
上面赞成的示例仅显示消息。它不会发送出去。而且它不编译。
因此，首先您需要将这些引用添加到您的.NET项目中：
就像我在对他的 OP 的评论中所说的那样：
您将需要添加以下引用：(1) 从 .NET 选项卡添加 Microsoft.Office.Tools.Outlook for runtime v.4.0.*，然后 (2) 再次从 .NET 选项卡添加 Microsoft.Office.Interop.Outlook for就我而言，版本 14.0.0.0，以及 (3) COM 对象 Microsoft Office 12.0 Microsoft.Office.Core 对象库。
然后是发送电子邮件的代码：
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: "me@somewhere.com") -- 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: "recipient@gmail.com", or "recipient1@gmail.com; recipient2@gmail.com")
//'sCc' = email address sending to as Carbon Copy option. Can be multiple. In that case separate with semicolons or commas. (ex: "recipient@gmail.com", or "recipient1@gmail.com; recipient2@gmail.com")
//'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))
{
string[] arrAddTos = sToAddress.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 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;
}
下面是你如何使用它：
List<string> arrAttachFiles = new List<string>() { @"C:\Users\User\Desktop\Picture.png" };
bool bRes = sendEmailViaOutlook("senders_email@somewhere.com",
"john.doe@hotmail.com, jane_smith@gmail.com", null,
"Test email from script - " + DateTime.Now.ToString(),
"My message body - " + DateTime.Now.ToString(),
BodyType.PlainText,
arrAttachFiles,
null);
