The storage information about a bucket includes the used capacity of and the number of objects in the bucket. You can call ObsClient.GetBucketStorageInfo to obtain the bucket storage information. Sample 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/eu/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);
// Obtain the storage information about a bucket.
try
{
    GetBucketStorageInfoRequest request = new GetBucketStorageInfoRequest
    {
        BucketName = "bucketname",
    };
    GetBucketStorageInfoResponse response = client.GetBucketStorageInfo(request);
    Console.WriteLine("Get bucket storageinfo response: {0}", response.StatusCode);
    Console.WriteLine("ObjectNumber: {0}", response.ObjectNumber);
    Console.WriteLine("Size: {0}", response.Size);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}
