MifareClassic.RestoreAsync(Int32) Method

Definition

Copies a value block to the tag's temporary block on a thread-pool thread.

public System.Threading.Tasks.Task RestoreAsync(int blockIndex);
member this.RestoreAsync : int -> System.Threading.Tasks.Task

Parameters

blockIndex
Int32

The zero-based index of the source value block, from 0 through 255. The block must be available on the tag.

Returns

A task that represents the restore operation.

Remarks

This managed wrapper uses Task.Run to call Restore(Int32). Connect and authenticate the block's sector first. Await the task, then use TransferAsync(Int32) to copy the temporary value to a value block.

The synchronous method's connection, access, and NFC permission requirements apply. The method has no cancellation-token parameter. Calling Close() from another thread cancels blocked I/O with IOException. Exceptions from the synchronous call are reported through the task.
