CopyTo(Int64, OracleBlob, Int64, Int64)

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.
