This instance method copies data from the current OracleBFile instance to the provided OracleBlob object with the specified source offset, destination offset, and character amounts.

Declaration

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

Parameters

• src_offset

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

• obj

  An OracleBlob object to which the data is copied.

• dst_offset

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

• amount

  The amount of data to be copied.

Return Value

The return value is the amount copied.

Exceptions

ObjectDisposedException - The object is already disposed.

ArgumentOutOfRangeException - The src_offset, the dst_offset, or the amount 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.
