C＃编程读取从Exchange服务器的邮件 [英] c# programmatically reading emails from the Exchange server

问题描述

当你在网上搜索，你会发现如何阅读电子邮件编程......阿尔网站的解释大多是同这样的页面很简单的答案。
http://omegacoder.com/?p=454

  //依赖从Exchange服务器版本
 service.Credentials =新的NetworkCredential（MDR，密码，ZZZ）; 
 service.AutodiscoverUrl（[e-mail]）; 
对象o = service.FindItems（WellKnownFolderName.Inbox，新ItemView控件（10））; 
 FindItemsResults<项目> findResults = service.FindItems（WellKnownFolderName.Inbox，新ItemView控件（10））; 
的foreach（在findResults.Items项项）
 {
 Console.WriteLine（item.Subject）; 
} 
  

它时，它执行autodiscoverURL线失败。错误说自动发现服务找不到。

于是我进一步一派，从微软的 https://www.testexchangeconnectivity.com/#&&/wEXAQUBcwUBME93h2+JjI0+MV2gTqcRL0g43z9m 在这里，你可以测试你的邮件服务器....
当我通过我得到的参数下面....

但我还是不明白的问题是什么？我需要一个记录添加到DNS？有人可以帮忙吗？

解决方案

您不一定需要使用自动搜索，如果你已经知道你的Exchange服务器的地址。请尝试以下代替（更多信息，请看 href=\"http://msdn.microsoft.com/en-us/library/dd633692%28v=exchg.80%29.aspx\">：

  service.Url =新的URI（HTTPS：//hostname/EWS/Exchange.asmx）; 
  

替换主机名与主机名Exchange服务器。

When you search on web you will find very easy answers for "How to read emails programmatically"... Al the websites are explaining most of the same like this page. http://omegacoder.com/?p=454

// depends from Exchange server version      
        service.Credentials = new NetworkCredential("MDR", "password", "zzz");
        service.AutodiscoverUrl("[e-mail]");
        object o = service.FindItems(WellKnownFolderName.Inbox, new ItemView(10));
        FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(10));
        foreach (Item item in findResults.Items)
        {
            Console.WriteLine(item.Subject);
        }

it fails when it executes the autodiscoverURL line. The error says "The Autodiscover service couldn't be located."

So I googled further and found this site from Microsoft https://www.testexchangeconnectivity.com/#&&/wEXAQUBcwUBME93h2+JjI0+MV2gTqcRL0g43z9m Here you can test your mail server.... When I pass the parameters I get the error below....

But I still don't understand what the problem is? Do I need to add a record to DNS ? Can someone help?

解决方案

You don't necessarily need to use the autodiscovery if you already know the address of your exchange server. Try the following instead (for more info, look here:

service.Url = new Uri("https://hostname/EWS/Exchange.asmx");

Replace "hostname" with the hostname for your exchange server.
