如何从EWS exchange服务器访问特定的电子邮件

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
service.Credentials = new NetworkCredential("username", "password");
service.Url = new Uri("https://exchangeserver/ews/Exchange.asmx");

ItemView view = new ItemView(1); // 仅获取一封邮件
view.PropertySet = new PropertySet(BasePropertySet.FirstClassProperties);
view.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Descending); // 按接收时间降序排序

FindItemsResults<Item> results = service.FindItems(WellKnownFolderName.Inbox, view); // 在收件箱中查找邮件

if (results.Items.Count > 0)
{
    EmailMessage email = results.Items[0] as EmailMessage; // 获取第一封邮件

    // 在这里可以对邮件进行进一步的操作，如获取邮件的主题、发件人、收件人等信息
    string subject = email.Subject;
    string sender = email.From.Name;
    string recipient = email.ToRecipients[0].Address;

    // 输出邮件信息
    Console.WriteLine("Subject: " + subject);
    Console.WriteLine("Sender: " + sender);
    Console.WriteLine("Recipient: " + recipient);
}
