asp.net – 适用于多个用户的EWS通知中心

>拥有一个有权冒充所有用户的帐户.
>我通过提供用户名和帐户为该帐户创建服务
密码.
>我冒充用户并将用户的订阅添加到
连接
>我创建了另一个服务,它是主服务的关闭
相同的用户名和密码,将冒充其他用户
然后将订阅添加到同一连接

这是我的代码的两个部分.忘记LogDevice它只是内部的东西.
第一部分是详细的模拟并将服务添加到服务列表中
在我的情况下,服务列表是一个字典,userSMTP是密钥,这里的UserSMTP密钥是模拟帐户.

以下是调用上一个函数(即对所有用户)的代码,请记住,您应该以某种方式存储要模拟的每个帐户的电子邮件地址.

我会把订阅部分和添加到连接,但它有点难看,很难得到.但想法只是你应该有一个连接,然后你去你做的每个服务,然后`connection.AddSubscription(streamingSubscription);其中streamingSubscription是从服务中提取的.
