CopyTo(Int64, OracleClob, Int64, Int64)
This instance method copies data from the current OracleBFile instance to the provided OracleClob object with the specified source offset, destination offset, and amount of characters. 
                  
Declaration
// C# public Int64 CopyTo(Int64 src_offset,OracleClob obj,Int64 dst_offset, Int64 amount);
Parameters
- 
                        src_offsetThe offset (in characters) in the current instance, from which the data is read. 
- 
                        objAn OracleClobobject that the data is copied to.
- 
                        dst_offsetThe offset (in characters) at which the OracleClobobject is copied to.
- 
                        amountThe 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 OracleConnectionis 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 current OracleClob data, spaces are written into the OracleClob 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.
