CopyToAsync(Int64, OracleBlob, Int64, Int64, CancellationToken)

The CopyToAsync method returns a Task-based asynchronous version of OracleBlob.CopyTo().

Declaration

// C#
public Task<Int64> CopyToAsync(Int64 src_offset, OracleBlob obj, Int64 dst_offset, Int64 amount, CancellationToken cancellationToken);

Parameters

• src_offset

  The offset (in bytes) in the current instance, from which the data is read.

• obj

  The OracleBlob object to which the data is copied.

• dst_offset

  The offset (in bytes) at which the OracleBlob object is copied.

• amount

  The amount of data to be copied.

• cancellationToken

  The input cancellation token which can be used by the application to cancel the task

Return Value

Task<Int64> object representing the asynchronous operation immediately without blocking the calling thread for the whole duration of the query execution.

Exceptions

• ObjectDisposedException - The object is already disposed.

• ArgumentOutOfRangeException - The src_offset, the dst_offset, or the amount parameter is less than 0.

• InvalidOperationException - This exception is thrown if any of the following conditions exist:

  • The OracleConnection is not open or has been closed during the lifetime of the object.

  • The LOB object parameter has a different connection than the object.
