如何使用Amazon S3的SDK判断我的文件是否已成功从Amazon S3删除

我使用以下代码从S3中删除一个文件。但是我如何判断从S3中实际删除文件是否成功呢?


这些是成功返回的报头:


响应头:x-amz-id-2，值:|秘钥移除|
响应头:x-amz-request-id，值:CA3F42D7F3B9215E
响应头:日期，值:Tue, 2009年8月9日


而且不成功:


响应头:x-amz-id-2，值:fM3/|秘钥移除|+p+F2Adu1Rr3b2k
Amazon S3 Delete: Response Header: x-amz-request-id, Value: 0CFB9E7882F01BA3
响应头:Date, Value: Tue, 09 Aug 2011 21:23:12 GMT
响应头:Server，值:AmazonS3





报头之间的唯一区别(除了不同的请求ID)是从S3返回的额外行，该行具有Server, Value: AmazonS3值，但我不知道这对我来说是否是确定文件是否成功从S3删除的可靠方法

我如何修改c#代码来告诉我删除是否成功?

谢谢。

static void DeletingAnObject()

        }
