Properties

NameTypeDescription
Public Property BucketName System.String

The name of the bucket containing this object.

Public Property ChecksumAlgorithm System.Collections.Generic.List<System.String>

Gets and sets the property ChecksumAlgorithm.

The algorithm that was used to create a checksum of the object.

Public Property ETag System.String

Gets and sets the property ETag.

The entity tag is a hash of the object. The ETag reflects changes only to the contents of an object, not its metadata. The ETag may or may not be an MD5 digest of the object data. Whether or not it is depends on how the object was created and how it is encrypted as described below:

  • Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-S3 or plaintext, have ETags that are an MD5 digest of their object data.

  • Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-C or SSE-KMS, have ETags that are not an MD5 digest of their object data.

  • If an object is created by either the Multipart Upload or Part Copy operation, the ETag is not an MD5 digest, regardless of the method of encryption. If an object is larger than 16 MB, the Amazon Web Services Management Console will upload or copy that object as a Multipart Upload, and therefore the ETag will not be an MD5 digest.

Public Property Key System.String

The key of the object.

Public Property LastModified System.DateTime

The date and time the object was last modified. The date retrieved from S3 is in ISO8601 format. A GMT formatted date is passed back to the user.

Public Property Owner Amazon.S3.Model.Owner

The owner of the object.

Public Property Size System.Int64

The size of the object.

Public Property StorageClass Amazon.S3.S3StorageClass

The class of storage used to store the object.
