从 exchange 服务器读取外出办公室供其他用户使用 C#

Question

我正在尝试从我的 C# 程序中读取组织中其他用户的外出状态和消息。我们在本地运行 Exchange 2013。

此应用程序运行作为 Active Directory 帐户（有自己的交换邮箱），我不能使用模拟。

我花了一些时间尝试解决类似问题，例如：

这个用的是模仿
Read out of office from exchange server for other users 我没有使用 Outlook 对象模型
How to get Out of Office for another mailbox 再次禁止模仿我
http://gsexdev.blogspot.com/2011/11/using-mailtips-in-ews-to-get-oof-out-of.html 我没有参考 ExchangeServiceBinding，即使我使用 Microsoft.Exchange.WebServices.Data;
http://blogs.msdn.com/b/devmsg/archive/2014/06/03/ews-how-to-retrieve-the-oof-out-of-facility-settings-message-using-ews-for-an-exchange-user.aspx 这一个作为参数，urlname 我不确定 url 是从哪里来的。这个似乎是最有前途的，有什么想法是从哪里来的吗？

我想得到类似的东西：

public void checkOOF(string userEmail){
bool isOOF = checkstuff(userEmail);
string message;
if(isOOF)
   message = getOOFMessage(userEmail);
}

请帮我理解，谢谢。

http://blogs.msdn.com/b/devmsg/archive/2014/06/03/ews-how-to-retrieve-the-oof-out-of-facility-settings-message-using-ews-for-an-exchange-user.aspx This one takes as a paramater, urlname and I'm not sure where that url is coming from. This one seems the most promising though, any ideas where that comes from?

urlname 只是 EWS URL 如果您使用的是托管 API 而不是仅使用来自 service.url.

的值

http://gsexdev.blogspot.com/2011/11/using-mailtips-in-ews-to-get-oof-out-of.html I don't have reference to ExchangeServiceBinding, even though I'm using Microsoft.Exchange.WebServices.Data;

这是从 Exchange Web 服务 WSDL 文件生成的代理代码，请参阅 https://msdn.microsoft.com/en-us/library/office/dd877040(v=exchg.140).aspx (Microsoft.Exchange.WebServices.Data) 是托管的 API。

这就是我最终使用的并且有效。

public static string getOOM(string emailToCheck) //needs to be full email of user.
{
            string EWSurl = String.Format("https://{0}/EWS/Exchange.asmx", ExchangePath);
            WebRequest webRequest = WebRequest.Create(EWSurl);
            HttpWebRequest httpwebRequest = (HttpWebRequest)webRequest;
            httpwebRequest.Method = "POST";
            httpwebRequest.ContentType = "text/xml; charset=utf-8";
            httpwebRequest.ProtocolVersion = HttpVersion.Version11;
            httpwebRequest.Credentials = new NetworkCredential("user", "password", "domain");//service Account
            httpwebRequest.Timeout = 60000;
            Stream requestStream = httpwebRequest.GetRequestStream();
            StreamWriter streamWriter = new StreamWriter(requestStream, Encoding.ASCII);

            StringBuilder getMailTipsSoapRequest = new StringBuilder("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"");
            getMailTipsSoapRequest.Append(" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" ");
            getMailTipsSoapRequest.Append("xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" ");
            getMailTipsSoapRequest.Append("xmlns:t=\"http://schemas.microsoft.com/exchange/services/2006/types\"><soap:Header>");
            getMailTipsSoapRequest.Append(" <t:RequestServerVersion Version=\"Exchange2010\"/></soap:Header><soap:Body>");
            getMailTipsSoapRequest.Append("<GetMailTips xmlns=\"http://schemas.microsoft.com/exchange/services/2006/messages\">");
            getMailTipsSoapRequest.Append("<SendingAs>");
            getMailTipsSoapRequest.Append("<t:EmailAddress>accessingemail@domain.com</t:EmailAddress>");
            getMailTipsSoapRequest.Append("<t:RoutingType>SMTP</t:RoutingType></SendingAs>");
            getMailTipsSoapRequest.Append("<Recipients><t:Mailbox>");
            getMailTipsSoapRequest.Append("<t:EmailAddress>" + emailToCheck + "</t:EmailAddress>");
            getMailTipsSoapRequest.Append("<t:RoutingType>SMTP</t:RoutingType></t:Mailbox></Recipients>");
            getMailTipsSoapRequest.Append(" <MailTipsRequested>OutOfOfficeMessage</MailTipsRequested></GetMailTips>");
            getMailTipsSoapRequest.Append("</soap:Body></soap:Envelope>");

            streamWriter.Write(getMailTipsSoapRequest.ToString());
            streamWriter.Close();
            HttpWebResponse webResponse = (HttpWebResponse)httpwebRequest.GetResponse();

            StreamReader streamreader = new StreamReader(webResponse.GetResponseStream());
            string response = streamreader.ReadToEnd();
            if (response.Contains("<t:Message/>"))
                return null;
            int messageIndex = response.IndexOf("<t:Message>");
            response = response.Substring(messageIndex, response.IndexOf("</t:Message>") - messageIndex);
            return response;
}

Aaron 提供的解决方案对我来说效果很好。然而，返回子字符串给我带来了问题，因为我们的字符串是 html 字符串而不是纯文本，而且它没有正确解析。所以我用以下内容替换了 StreamReader 的向下部分。这仍然是 returns 作为字符串但正确解析为 html 它被返回为。

        XDocument doc;
        using (Stream responseStream = response.GetResponseStream())
        {
            doc = XDocument.Load(responseStream);
        }
        return doc.Root.Descendants().Where(d => d.Name.LocalName == "Message").Select(d => d.Value).FirstOrDefault();
