使用AWSSDK .NET /使用.net中的AWS快照创建新快照并删除旧快照

Question

我找不到任何有关如何创建或删除快照的好的文档。所以这就是我所做的。因此，这是创建新快照并删除旧快照的解决方案

从Visual Studio中的nuget Manager添加AWSSDK.Core / AWSSDK.EC2 / AWSSDK.S3库。

有关创建快照的更多信息，请参见：https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/EC2/MEC2CreateSnapshotCreateSnapshotRequest.html

有关描述快照的更多信息，请参阅： https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/EC2/TDescribeSnapshotsRequest.html
