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

This method returns a Task-based asynchronous version of OracleBFile.CopyTo(), which copies data from the current instance to the provided object.

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.
