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
OracleBlobobject to which the data is copied. -
dst_offset
The offset (in bytes) to which the
OracleBlobobject 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
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 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.
