AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

This implementation of the DELETE operation uses the policy subresource to delete the policy of a specified bucket. If you are using an identity other than the root user of the AWS account that owns the bucket, the calling identity must have the DeleteBucketPolicy permissions on the specified bucket and belong to the bucket owner's account to use this operation.

If you don't have DeleteBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.

As a security precaution, the root user of the AWS account that owns a bucket can always use this operation, even if the policy explicitly denies the root user the ability to perform this action.

For more information about bucket policies, see Using Bucket Policies and UserPolicies.
