要在 Microsoft Outlook 中使用 Office 自动化对象，请向项目添加对 Microsoft Office 和 Microsoft Office Interop for Outlook 库的引用。运行代码的机器上还必须安装 Microsoft Office Outlook。
VSTO
// Create Application class and get namespace
Outlook.Application outlook = new Outlook.Application();
Outlook.NameSpace ns = outlook.GetNamespace("Mapi");
object _missing = Type.Missing;
ns.Logon(_missing, _missing, false, true);
// Get Inbox information in objec of type MAPIFolder
Outlook.MAPIFolder inbox = ns.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
// Unread emails
int unread = inbox.UnReadItemCount;
// Display the subject of emails in the Inbox folder
foreach (Outlook.MailItem mail in inbox.Items)
{
Console.WriteLine(mail.Subject);
}
Aspose.Email
然而，运行代码的机器上不需要安装 Microsoft Outlook。引用 Aspose.Email.dll 即可成功构建和运行项目。
// Create instance of ExchangeClient class by giving credentials
ExchangeClient client = new ExchangeClient("http://MachineName/exchange/Username",
"username", "password", "domain");
// Call ListMessages method to list messages info from Inbox
ExchangeMessageInfoCollection msgCollection = client.ListMessages(client.MailboxInfo.InboxUri);
// Loop through the collection to display the basic information
foreach (ExchangeMessageInfo msgInfo in msgCollection)
{
Console.WriteLine("Subject: " + msgInfo.Subject);
Console.WriteLine("From: " + msgInfo.From.ToString());
Console.WriteLine("To: " + msgInfo.To.ToString());
Console.WriteLine("Message ID: " + msgInfo.MessageId);
Console.WriteLine("Unique URI: " + msgInfo.UniqueUri);
Console.WriteLine("==================================");
}
