This instance method copies data from the current OracleBlob instance to the provided OracleBlob object with the specified destination offset.

Declaration

// C#
public Int64 CopyTo(OracleBlob obj, Int64 dst_offset);

Parameters

• obj

  The OracleBlob object to which the data is copied.

• dst_offset

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

Return Value

The return value is the amount copied.

Exceptions

ObjectDisposedException - The object is already disposed.

ArgumentOutOfRangeException - The dst_offset 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.

Remarks

If the dst_offset is beyond the end of the OracleBlob data, spaces are written into the OracleBlob until the dst_offset is met.

The offsets are 0-based. No character conversion is performed by this operation.

The provided object and the current instance must be using the same connection; that is, the same OracleConnection object.
