You can call ObsClient.ListBuckets to list buckets. 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);
// List buckets.
try
{
    ListBucketsRequest request = new ListBucketsRequest();
    ListBucketsResponse response = client.ListBuckets(request);
    request.IsQueryLocation = true;
    foreach (ObsBucket bucket in response.Buckets)
    {
        Console.WriteLine("Bucket name is : {0}", bucket.BucketName);
        Console.WriteLine("Bucket creationDate is : {0}", bucket.CreationDate);
        Console.WriteLine("Bucket location is : {0}", bucket.Location);
        Console.WriteLine("\n");
    }
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}

NOTE:

Obtained bucket names are listed in the lexicographical order.
Set ListBucketsRequest.IsQueryLocation to true and then you can query the bucket location when listing buckets.
