Objects are the basic unit for data operations in Object Storage Service (OSS). OSS SDK for .NET provides the following methods to upload objects:

  • Simple upload: supports the upload of an object that is up to 5 GB in size.

  • Append upload: supports the upload of an object that is up to 5 GB in size.

  • Resumable upload: supports the upload of an object that is up to 48.8 TB in size. This method is suitable for uploading large objects. Concurrent upload is supported. You can specify the size of parts.

  • Multipart upload: supports the upload of an object that is up to 48.8 TB in size. This method is suitable for uploading large objects.
