Removes an object from a bucket. The behavior depends on the bucket's versioning state:
If bucket versioning is not enabled, the operation permanently deletes the object.
If bucket versioning is enabled, the operation inserts a delete marker, which becomes
the current version of the object. To permanently delete an object in a versioned
bucket, you must include the object’s versionId in the request. For more information
about versioning-enabled buckets, see Deleting
object versions from a versioning-enabled bucket.
If bucket versioning is suspended, the operation removes the object that has a null
versionId, if there is one, and inserts a delete marker that becomes the current
version of the object. If there isn't an object with a null versionId, and
all versions of the object have a versionId, Amazon S3 does not remove the
object and only inserts a delete marker. To permanently delete an object that has
a versionId, you must include the object’s versionId in the request.
For more information about versioning-suspended buckets, see Deleting
objects from versioning-suspended buckets.
Directory buckets - S3 Versioning isn't enabled and supported for directory
buckets. For this API operation, only the null value of the version ID is supported
by directory buckets. You can only specify null to the versionId query
parameter in the request.
Directory buckets - For directory buckets, you must make requests for this
API operation to the Zonal endpoint. These endpoints support virtual-hosted-style
requests in the format https://amzn-s3-demo-bucket.s3express-zone-id.region-code.amazonaws.com/key-name. Path-style requests are not supported. For more information about endpoints
in Availability Zones, see Regional
and Zonal endpoints for directory buckets in Availability Zones in the Amazon
S3 User Guide. For more information about endpoints in Local Zones, see Concepts
for directory buckets in Local Zones in the Amazon S3 User Guide.
To remove a specific version, you must use the versionId query parameter. Using
this query parameter permanently deletes the version. If the object deleted is a delete
marker, Amazon S3 sets the response header x-amz-delete-marker to true.
If the object you want to delete is in a bucket where the bucket versioning configuration
is MFA Delete enabled, you must include the x-amz-mfa request header in the
DELETE versionId request. Requests that include x-amz-mfa must use HTTPS.
For more information about MFA Delete, see Using
MFA Delete in the Amazon S3 User Guide. To see sample requests that use
versioning, see Sample
Request.
Directory buckets - MFA delete is not supported by directory buckets.
You can delete objects by explicitly calling DELETE Object or calling (PutBucketLifecycle)
to enable Amazon S3 to remove them for you. If you want to block users or accounts
from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject,
s3:DeleteObjectVersion, and s3:PutLifeCycleConfiguration actions.
Directory buckets - S3 Lifecycle is not supported by directory buckets.
General purpose bucket permissions - The following permissions are required
in your policies when your DeleteObjects request includes specific headers.
s3:DeleteObject - To delete an object from a bucket, you must always
have the s3:DeleteObject permission.
s3:DeleteObjectVersion - To delete a specific version of an object
from a versioning-enabled bucket, you must have the s3:DeleteObjectVersion
permission.
Directory bucket permissions - To grant access to this API operation on a
directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically,
you grant the s3express:CreateSession permission to the directory bucket in
a bucket policy or an IAM identity-based policy. Then, you make the CreateSession
API call on the bucket to obtain a session token. With the session token in your request
header, you can make API requests to this operation. After the session token expires,
you make another CreateSession API call to generate a new session token for
use. Amazon Web Services CLI or SDKs create session and refresh the session token
automatically to avoid service interruptions when a session expires. For more information
about authorization, see CreateSession.
Directory buckets - The HTTP Host header syntax is Bucket-name.s3express-zone-id.region-code.amazonaws.com.
The following action is related to DeleteObject:
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginDeleteObject and EndDeleteObject.

Assembly: AWSSDK.S3.dll
Version: 3.x.y.z
public virtual Task<DeleteObjectResponse> DeleteObjectAsync( DeleteObjectRequest request, CancellationToken cancellationToken )
Container for the necessary parameters to execute the DeleteObject service method.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
