我正在开发一种Windows服务，它使用service.create()方法读取CSV文件并将记录添加到Dynamics CRM 2011。它引发了以下异常，我无法确定原因：

Exception Message: The request was aborted: The request was canceled.

Inner Exception:

Answer 1

组织服务最终是一个WCF服务......你可以享受内部部署的好处，也许你发送的请求太大或者CRM很忙，无法回复你的请求在超时之前。

无论如何，您可能需要考虑增加Binding配置中的超时值。

您的问题可能是由连接超时引起的。对于异步操作，WCF不会在连接超时时抛出TimeoutException。相反，它将使用Status WebExceptionStatus.RequestCanceled抛出具有内部异常WebException的CommunicationException。

响应超时对同步和异步操作抛出TimeoutException。

连接到Dynamics CRM投掷“请求已中止：请求已取消。”例外
