我正在控制台应用程序中工作，我使用下面的 C# 代码在按钮单击事件上自动发送邮件，
public void SendMail()
{
//// Create the Outlook application by using inline initialization.
Outlook.Application oApp = new Outlook.Application();
////Create the new message by using the simplest approach.
Outlook.MailItem oMsg = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);
//Add a recipient.
// TODO: Change the following recipient where appropriate.
Outlook.Recipients oRecips = oMsg.Recipients;
List<string> oTORecip = new List<string>();
List<string> oCCRecip = new List<string>();
oTORecip.Add("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a0c5d8c1cdd0ccc5e0d4c5d3d48ec3cfcd" rel="noreferrer noopener nofollow">[email protected]</a>");
oCCRecip.Add("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2e4b564f435e424b6e5a4b5d5a004d4143" rel="noreferrer noopener nofollow">[email protected]</a>");
foreach (string t in oTORecip)
{
Outlook.Recipient oTORecipt = oRecips.Add(t);
oTORecipt.Type = (int)Outlook.OlMailRecipientType.olTo;
oTORecipt.Resolve();
}
foreach (string t in oCCRecip)
{
Outlook.Recipient oCCRecipt = oRecips.Add(t);
oCCRecipt.Type = (int)Outlook.OlMailRecipientType.olCC;
oCCRecipt.Resolve();
}
//Set the basic properties.
oMsg.Subject = "TestMail- " + DateTime.Today.ToString("MM/dd/yyyy");
oMsg.HTMLBody = "<html>" +
"<head>" +
"<title>TestMail</title>" +
"</head>" +
"<body style='background-color:#E6E6E6;'>" +
"<div style='font-family: Georgia, Arial; font-size:14px; '>Hi,<br /><br />" +
"PFA<br />" +
"This is Test Mail.Please Ignore.<br /><br /><br /><br /><br />" +
"Thanks & Regards<br />" +
"test"+
"</div>" +
"</body>" +
"</html>";
string date = DateTime.Today.ToString("MM-dd-yyyy");
//Add an attachment.
// TODO: change file path where appropriate
String sSource = "D:\\Test\\test_" + date + ".xlsx";
String sDisplayName = "MyFirstAttachment";
int iPosition = (int)oMsg.Body.Length + 1;
int iAttachType = (int)Outlook.OlAttachmentType.olByValue;
Outlook.Attachment oAttach = oMsg.Attachments.Add(sSource, iAttachType, iPosition, sDisplayName);
// If you want to, display the message.
// oMsg.Display(true); //modal
//Send the message.
oMsg.Save();
oMsg.Send();
//Explicitly release objects.
oTORecip = null;
oCCRecip = null;
oAttach = null;
oMsg = null;
oApp = null;
}
这段代码工作正常。我想使用另一个帐户发送邮件。如何在上面的代码中给出发件人地址？ 是否可以这样做？我需要使用什么 C# 代码来使用 C# 代码代表其他帐户发送邮件？
最佳答案
在 oMsg 上设置 MailItem.SendUsingAccount 属性
http://msdn.microsoft.com/en-us/library/office/ff869311%28v=office.14%29.aspx
您只能从 Application.Session.Accounts 集合中进行选择。
或者可能检查
MailItem.SentOnBehalfOfName http://msdn.microsoft.com/en-us/library/office/ff862145%28v=office.14%29.aspx
(用于交换)

以下代码可以使用智能感知，请检查您的 DLL 版本。使用 Outlook PIA v 14 和 v 12 进行检查。
包下载自 http://www.microsoft.com/en-us/download/details.aspx?id=43664
using Microsoft.Office.Interop.Outlook;
//C:\Program Files\Microsoft Visual Studio 11.0\Visual Studio Tools for Office\PIA\Office14\Microsoft.Office.Interop.Outlook.dll
//14.0.0.0 or 12.0.0.0 - it works from Outlook 2007 and higher
namespace ConsoleApplication1
{
class Program
{
public void SendMail()
{
//// Create the Outlook application by using inline initialization.
Application oApp = new Application();
////Create the new message by using the simplest approach.
MailItem oMsg = (MailItem)oApp.CreateItem(OlItemType.olMailItem);
oMsg.SendUsingAccount = oApp.Session.Accounts[2]; // it starts at 1
...
您似乎正在使用其他一些程序集 DLL，因为对我来说，语句“using Microsoft.Office.Interop;”根本不起作用。
