如何使用C#中的EWS从Exchange获取HTML和TEXT中的电子邮件正文？

Question

我有一个应用程序,使用EWS从交换机中读取电子邮件.我的问题是,获取电子邮件的HTML版本是一个电话,并获得电子邮件的TEXT版本是另一个电话.

有没有第三方控件可以在一次调用中获取两种格式？

有一些示例代码会很棒.

看看Exchange Server开发论坛上的这个帖子,我想它会回答你的问题.http://social.technet.microsoft.com/Forums/exchange/en-US/3c95b323-1ba2-4bc5-80bd-f5626707db6a/i-need-the-htmltext-and-the-plaintext-of-the-body-的-AN-项目类型？论坛= exchangesvrdevelopment

我玩这个,所以我可以提供一个代码示例,事实证明你不必使用扩展属性.默认情况下,EWS在EmailMessageSchema.Body中返回HTML格式的主体 - 因此,如果您创建的属性集包含ItemSchema.TextBody和EmailMessageSchema.Body,则可以在一个Bind调用中获取这两种类型.

public static void GetEmail(ExchangeService service, ItemId ItemId)
{
    PropertySet propSet = new PropertySet(BasePropertySet.IdOnly, ItemSchema.TextBody, EmailMessageSchema.Body);
    EmailMessage message = EmailMessage.Bind(service, ItemId, propSet);
}

这会产生以下XML请求:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

        <t:FieldURI FieldURI="item:Body" />
      </t:AdditionalProperties>
    </m:ItemShape>
    <m:ItemIds>
      <t:ItemId Id="AAMkADE4..." />
    </m:ItemIds>
  </m:GetItem>
</soap:Body>
