我正在使用exchange web service(EWS)从exchange服务器读取电子邮件。
我想阅读来自DateTimeSent大于datetime.now的exchange服务器的电子邮件。
我没有使用searchfilter和viewbase，它们是FindItems的参数，如何使用它们?

       //Email exchange starts here
    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1)
    {
        Credentials = new WebCredentials(credentials.SmtpUser, credentials.SmtpPassword)
    };
    //to add logic for itemview
    service.AutodiscoverUrl(credentials.SmtpFromAddress, RedirectionUrlValidationCallback);
    //var inbox = service.FindItems(WellKnownFolderName.Inbox, new ItemView(100));
      var inbox = service.FindItems(WellKnownFolderName.Inbox,); //what to add here?
    foreach (EmailMessage item in inbox.Items.Where(x => Convert.ToDateTime(x.DateTimeSent) > dateTime.Now))
    {
    }

如何在microsoft exchange web service (EWS)中使用搜索过滤器和viewbase

我不知道DateTimeSent如何大于DateTime.Now以及为什么需要它，但以下是一个如何执行搜索的示例:

string email = "<user>@<host>";
string user = "<user>";
string password = "<password>";
string serviceUrl = "https://<url>/ews/exchange.asmx";
Mailbox mailbox = new Mailbox(email);
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.Credentials = new WebCredentials(user, password);
service.Url = new Uri(serviceUrl);
FolderId inbox = new FolderId(WellKnownFolderName.Inbox, mailbox);
SearchFilter searchFilter = new SearchFilter.IsGreaterThan(ItemSchema.DateTimeSent, DateTime.Now);
ItemView view = new ItemView(10); // take 10 items
view.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Descending);
FindItemsResults<Item> result = service.FindItems(inbox, searchFilter, view);
