Applies an Amazon S3 bucket policy to an Amazon S3 bucket. If you are using an identity
other than the root user of the Amazon Web Services account that owns the bucket,
the calling identity must have the PutBucketPolicy permissions on the
specified bucket and belong to the bucket owner's account in order to use this operation.
If you don't have PutBucketPolicy 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 Amazon Web Services 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, see Bucket policy examples.

This example shows how to Get, Put and Delete bucket policies.
// Create a client
AmazonS3Client client = new AmazonS3Client();
// Put sample bucket policy (overwrite an existing policy)
string newPolicy = @"{
""Statement"":[{
""Sid"":""BasicPerms"",
""Effect"":""Allow"",
""Principal"": ""*"",
""Action"":[""s3:PutObject"",""s3:GetObject""],
""Resource"":[""arn:aws:s3:::samplebucketname/*""]
}]}";
PutBucketPolicyRequest putRequest = new PutBucketPolicyRequest
{
BucketName = "SampleBucket",
Policy = newPolicy
};
client.PutBucketPolicy(putRequest);
// Retrieve current policy
GetBucketPolicyRequest getRequest = new GetBucketPolicyRequest
{
BucketName = "SampleBucket"
};
string policy = client.GetBucketPolicy(getRequest).Policy;
Console.WriteLine(policy);
Debug.Assert(policy.Contains("BasicPerms"));
// Delete current policy
DeleteBucketPolicyRequest deleteRequest = new DeleteBucketPolicyRequest
{
BucketName = "SampleBucket"
};
client.DeleteBucketPolicy(deleteRequest);
// Retrieve current policy and verify that it is null
policy = client.GetBucketPolicy(getRequest).Policy;
Debug.Assert(policy == null);
