Object Storage Service:Delete object tags

Prerequisites

Before you begin, make sure that you have:

• An AccessKey pair with the oss:DeleteObjectTagging permission. For more information, see Grant custom access policies to RAM users

• The AlibabaCloud.OSS.V2 NuGet package installed in your project

Background

Object tags are key-value pairs used to classify and manage objects. When tags are no longer needed, delete them with the DeleteObjectTaggingAsync method. This removes all tags from the specified object in a single call.

For more information about object tagging, see Object tagging. For the API specification, see DeleteObjectTagging.

Sample code

The following example uses the China (Hangzhou) region (cn-hangzhou) with a public endpoint. To access OSS from another Alibaba Cloud service in the same region, use an internal endpoint instead. For more information, see Regions and endpoints.

using OSS = AlibabaCloud.OSS.V2;

// Specify the region and target object.
var region = "cn-hangzhou";
var endpoint = null as string;
var bucket = "<your-bucket-name>";
var key = "<your-object-key>";

// Load the default SDK configuration.
// Credentials are read from the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables.
var cfg = OSS.Configuration.LoadDefault();
cfg.CredentialsProvider = new OSS.Credentials.EnvironmentVariableCredentialsProvider();
cfg.Region = region;

// If an endpoint is specified, override the default endpoint.
if (endpoint != null)
{
    cfg.Endpoint = endpoint;
}

using var client = new OSS.Client(cfg);

var result = await client.DeleteObjectTaggingAsync(new()
{
    Bucket = bucket,
    Key = key
});

Console.WriteLine("DeleteObjectTagging done");
Console.WriteLine($"StatusCode: {result.StatusCode}");
Console.WriteLine($"RequestId: {result.RequestId}");
Console.WriteLine("Response Headers:");
result.Headers.ToList().ForEach(x => Console.WriteLine(x.Key + " : " + x.Value));

Replace the following placeholders with your actual values:
