In Object Storage Service (OSS), an object is the basic unit of data. The OSS SDK for C# provides several ways to upload objects:
Simple upload (C# SDK V1): The maximum object size is 5 GB.
Append upload (C# SDK V1): The maximum object size is 5 GB.
Resumable upload (C# SDK V1): Supports resuming interrupted uploads, concurrent uploads, and custom part sizes. This method is recommended for large objects. The maximum object size is 48.8 TB.
Multipart upload (C# SDK V1): Use this method for large objects. The maximum object size is 48.8 TB.
During an upload, you can set object metadata and view the upload progress using the progress bar chart (C# SDK V1). After the upload is complete, you can also configure an upload callback (C# SDK V1).
