Sending Email through Outlook 2010 via C#
提问by SteveAnselment
I am trying to send an email from inside my C# console App. I have added the references and using statements but it seems I have not added everything I need. This is the first time I have ever attempted to do this so I figure there is something I have forgotten.
我正在尝试从我的 C# 控制台应用程序内部发送电子邮件。我已经添加了引用和使用语句，但似乎我没有添加我需要的一切。这是我第一次尝试这样做，所以我想我已经忘记了一些事情。
I got this code snippet from the MSDN site http://msdn.microsoft.com/en-us/library/vstudio/ms269113(v=vs.100).aspx
我从 MSDN 站点http://msdn.microsoft.com/en-us/library/vstudio/ms269113(v=vs.100).aspx得到了这个代码片段
Here is the code that I am getting issues with in VS 2010
这是我在 VS 2010 中遇到问题的代码
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);
}
}
}

replace the line
更换线
Outlook.MailItem mailItem = (Outlook.MailItem)
this.Application.CreateItem(Outlook.OlItemType.olMailItem);
with
和
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);
Hope this helps,

This is how you can send an email via Microsoft Office Outlook. In my case I was using Office 2010, but I suppose it should work with newer versions.
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，但我认为它应该适用于较新的版本。
The upvoted sample above just displays the message. It does not send it out. Moreover it doesn't compile.
上面的 upvoted 示例只显示消息。它不发送它。而且它不编译。
So first you need to add these references to your .NETproject:
所以首先你需要将这些引用添加到你的.NET项目中：
Like I said in my comment to his OP:
就像我在对他的 OP 的评论中所说的那样：
You will need to add the following references: (1) From .NET tab add Microsoft.Office.Tools.Outlook for runtime v.4.0.*, then (2) again from .NET tab add Microsoft.Office.Interop.Outlook for version 14.0.0.0 in my case, and (3) COM object Microsoft Office 12.0 Object Library for Microsoft.Office.Core.
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在我的情况下是 14.0.0.0 版，以及 (3) Microsoft.Office.Core 的 COM 对象 Microsoft Office 12.0 对象库。
Then here's the code to send out emails:
然后这里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: "[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))
{
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;
}
And here's how you'd use it:
这是你如何使用它：
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);

You need to cast theapp.CreateItem(Outlook.OlItemType.olMailItem)
object inOutlook.MailItem mailItem = app.CreateItem(Outlook.OlItemType.olMailItem)
toOutlook.MailItemtype
since no implicit casting is available.
您需要将app.CreateItem(Outlook.OlItemType.olMailItem)
对象转换Outlook.MailItem mailItem = app.CreateItem(Outlook.OlItemType.olMailItem)
为Outlook.MailItem类型，
因为没有可用的隐式转换。
Replace
代替
Outlook.MailItem mailItem = app.CreateItem(Outlook.OlItemType.olMailItem);
with
和
Outlook.MailItem mailItem = (Outlook.MailItem)app.CreateItem(Outlook.OlItemType.olMailItem);
