Master Huawei OBS eSDK Storage: Build C# Apps with Full SDK Capabilities

Earlier this year Huawei held a training session on OBS (Object Storage Service) eSDK storage, and many participants found the material challenging. This article organizes the key points of that training.

Huawei OBS is used for personal cloud backup and online storage, as well as enterprise centralized backup and active archiving.

OBS SDK provides four main capabilities:

Bucket operations include:

Check if a bucket exists (HeadBucket)

List buckets (ListBuckets)

Get bucket location (GetBucketLocation)

Create bucket (CreateBucket)

Delete bucket (DeleteBucket)

List objects in a bucket (ListObjects)

Get bucket ACL (GetBucketAcl)

Set bucket ACL (SetBucketAcl)

Get bucket logging configuration (GetBucketLoggingConfiguration)

The eSDK storage SDK is open‑source and currently supports Android, C#, iOS, C++, Go, Java, Node.js, PHP, Python, Ruby and other languages.

Object operations include:

Upload content (PutObject)

Get object content (GetObject)

Delete object (DeleteObject)

Copy object (CopyObject)

Get object ACL (GetObjectAcl)

Set object ACL (SetObjectAcl)

Upload part (UploadPart)

Copy part (CopyPart)

Abort multipart upload (AbortMultipartUpload)

How to set up an OBS C# SDK development environment?

First, obtain the eSDK storage development tools and materials, such as Visual Studio or another IDE, and the necessary header files and shared libraries for OBS.

The available materials include SDK packages and documentation (illustrated in the following image).

With these tools, developers can use the SDK to:

Create a bucket

List buckets

Upload objects

Download objects

Query objects

Host a bucket as a static website

Examples (C# demos) are shown below:
