Query the region of a bucket using OSS SDK for C# 1.0

Call GetBucketLocation using the OSS SDK for C# 1.0 to retrieve the region where a bucket is located.

Usage notes

• The sample code uses the public endpoint for the China (Hangzhou) region. To access OSS from another Alibaba Cloud service in the same region, use an internal endpoint instead. For a full list of regions and endpoints, see Regions and Endpoints.

• The sample code creates an OSSClient instance using an OSS endpoint. To create an OSSClient instance using a custom domain name or Security Token Service (STS), see Initialization.

• To query the region of a bucket, you must have the oss:GetBucketLocation permission. For more information, see Grant a custom policy.

using Aliyun.OSS;
using Aliyun.OSS.Common;
// Specify the endpoint of a region that is supported by OSS. Example: 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 bucket name. 
var bucketName = "yourBucketName";
// Specify the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the region to cn-hangzhou.
const string region = "cn-hangzhou";

// Create a ClientConfiguration instance and modify parameters as required.
var conf = new ClientConfiguration();

// Use the signature algorithm V4.
conf.SignatureVersion = SignatureVersion.V4;

// Create an OSSClient instance. 
var client = new OssClient(endpoint, accessKeyId, accessKeySecret, conf);
client.SetRegion(region);
try
{
    // Query the region of the bucket. 
    var result = client.GetBucketLocation(bucketName);
    Console.WriteLine("Get bucket:{0} Info succeeded ", bucketName);
    Console.WriteLine("bucket Location: {0}", result.Location);
