ServiceException Class

表示阿里云服务返回的错误消息。

ServiceException用于处理阿里云服务返回的错误消息。比如，用于身份验证的AccessKeyID不存在，则会抛出ServiceException。异常中包含了错误代码，用于让调用者进行特定的处理。

WebException表示的则是在向阿里云服务发送请求时出现的错误。例如，在发送请求时网络连接不可用，则会抛出WebException的异常。

InvalidOperationException表示客户端代码无法处理或解析返回结果。这种情况有可能是服务器返回的结果不完整，或不再符合SDK设计时的规范。如果持续遇到该错误，请考虑升级 SDK版本，或联系我们。

通常来讲，调用者只需要处理ServiceException。因为该异常表明请求被服务处理，但处理的结果表明存在错误。异常中包含了细节的信息，特别是错误代码，可以帮助调用者进行处理。
