Deleting Versioning Objects

If you have any questions during the development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

Deleting a Single Versioning Object

You can call ObsClient.DeleteObject to pass a version ID (VersionId) to delete an object version.

This example deletes object objectname from bucket bucketname by specifying VersionId.

The example code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
string accessKey= Environment.GetEnvironmentVariable("AccessKeyID", EnvironmentVariableTarget.Machine);
string secretKey= Environment.GetEnvironmentVariable("SecretAccessKey", EnvironmentVariableTarget.Machine);
// Create an instance of ObsClient.
ObsClient client = new ObsClient(accessKey, secretKey, config);
// Delete a versioning object.
try
{
    DeleteObjectRequest request = new DeleteObjectRequest()
    {
        BucketName = "buckername",
        ObjectKey = "objectname",
        VersionId = "versionId"
    };
    DeleteObjectResponse response = client.DeleteObject(request);
    Console.WriteLine("Delete object response: {0}", response.StatusCode);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}

Deleting Versioning Objects in a Batch

You can call ObsClient.DeleteObjects to batch delete specific versions of an object by passing the VersionId value of each version to delete.

This example deletes objects objectname1 and objectname2 from bucket bucketname in a batch by specifying their version IDs.

The example code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
string accessKey= Environment.GetEnvironmentVariable("AccessKeyID", EnvironmentVariableTarget.Machine);
string secretKey= Environment.GetEnvironmentVariable("SecretAccessKey", EnvironmentVariableTarget.Machine);
// Create an instance of ObsClient.
ObsClient client = new ObsClient(accessKey, secretKey, config);
// Delete two versioning objects.
try
{
    DeleteObjectsRequest request = new DeleteObjectsRequest();
    request.BucketName = "bucketname";
    request.Quiet = true;
    request.AddKey("objectName1", "versionId1");
    request.AddKey("objectName2", "versionId2");
    DeleteObjectsResponse response = client.DeleteObjects(request);
    Console.WriteLine("Delete objects response: {0}", response.StatusCode);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}
