Overloads
| CopyTo(OracleLob) |
Copies the entire contents of this OracleBFile to the beginning of a destination OracleLob. |
| CopyTo(OracleLob, Int64) |
Copies the entire contents of this OracleBFile to a destination OracleLob at the specified offset. |

CopyTo(OracleLob)
Copies the entire contents of this OracleBFile to the beginning of a destination OracleLob.
public:
long CopyTo(System::Data::OracleClient::OracleLob ^ destination);public long CopyTo (System.Data.OracleClient.OracleLob destination);member this.CopyTo : System.Data.OracleClient.OracleLob -> int64override this.CopyTo : System.Data.OracleClient.OracleLob -> int64Public Function CopyTo (destination As OracleLob) As LongParameters
Returns
The number of bytes copied.
Exceptions
The destination OracleLob is a null object reference.
The destination is a null OracleLob.
-or-
The connection with which this OracleBFile is associated is closed.
The OracleBFile object is closed or disposed.
Remarks
The underlying data types of the source OracleBFile and the destination OracleLob must be compatible. For example, you cannot copy binary data to a destination OracleLob that has a character data type.
You must have write access to the destination OracleLob for the CopyTo operation to execute correctly.
Applies to
CopyTo(OracleLob, Int64)
Copies the entire contents of this OracleBFile to a destination OracleLob at the specified offset.
