Object Storage Service:Delete buckets

Usage notes

• In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS by using other Alibaba Cloud services in the same region as OSS, use an internal endpoint. For more information about the regions and endpoints supported by OSS, see Regions and endpoints.

• In this topic, an OSSClient instance is created by using an OSS endpoint. If you want to create an OSSClient instance by using custom domain names or Security Token Service (STS), see Initialization.

• To delete a bucket, you must have the oss:DeleteBucket permission. For more information, see Attach a custom policy to a RAM user.

Prerequisites

• All objects in the bucket are deleted. You can manually delete objects from a bucket or have objects automatically deleted from a bucket based on a lifecycle rule.

  • If the bucket contains a small number of objects, we recommend that you manually delete them. For more information, see Delete objects.

  • To delete a large number of objects, we recommend that you configure lifecycle rules to delete the objects. For more information, see Lifecycle rules based on the last modified time.

    Important

    To delete a versioning-enabled bucket, make sure that all current and previous versions of objects in the bucket are deleted. For more information, see Overview.

• Parts generated by multipart upload or resumable upload tasks in the bucket are deleted. For more information, see Delete parts.

• All LiveChannels in the bucket are deleted. For more information, see DeleteLiveChannel.

Sample code

The following sample code shows how to delete a bucket named examplebucket:

using System;
using Aliyun.OSS;


namespace Samples
{
    public class Program
    {
        public static void Main(string[] args)
        {
            // Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. 
            var endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
            // Obtain access credentials from environment variables. Before you run the sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are configured. 
            var accessKeyId = Environment.GetEnvironmentVariable("OSS_ACCESS_KEY_ID");
            var accessKeySecret = Environment.GetEnvironmentVariable("OSS_ACCESS_KEY_SECRET");
            // Specify the name of the bucket. Example: examplebucket. 
            var bucketName = "examplebucket314";
            // Create an OSSClient instance. 
            var client = new OssClient(endpoint, accessKeyId, accessKeySecret);

            try
            {
                client.DeleteBucket(bucketName);

                Console.WriteLine("Delete bucket succeeded");
            }
            catch (Exception ex)
            {
                Console.WriteLine("Delete bucket failed. {0}", ex.Message);
            }
        }
    }
}
