Declaration
public abstract ValueTask<int> ReadAsync(long offset, Memory<byte> buffer, CancellationToken cancellationToken)Parameters
| Type | Name | Description |
|---|---|---|
| long | offset | The offset in the content of the first byte to read. |
| Memory<byte> | buffer | The buffer to read into. An upload never reads past Length. |
| CancellationToken | cancellationToken | A token to cancel the read. |
Returns
| Type | Description |
|---|---|
| ValueTask<int> | The number of bytes read, which can be less than the length of the buffer. Zero means that the content ends at the offset. |
Remarks
The same range can be read more than once. An exception that the read throws ends the upload, which aborts the upload on the service and throws it.
