    Public PropertyReadTimeoutGets or sets a value, in miliseconds, that determines how long the stream will attempt to read before timing out. (Inherited from System.IO.Stream)
    Public PropertyValueGets the value of the OracleLob object. (Inherited from Devart.Data.Oracle.OracleLob)
    Public PropertyWriteTimeoutGets or sets a value, in miliseconds, that determines how long the stream will attempt to write before timing out. (Inherited from System.IO.Stream)

    Public Methods
     NameDescription
    Public MethodAppendOverloaded. Appends the supplied data to the current OracleLob instance. (Inherited from Devart.Data.Oracle.OracleLob)
    Public MethodBeginBatchOverloaded. Prevents server-side triggers from firing while performing multiple write operations. (Inherited from Devart.Data.Oracle.OracleLob)
    Public MethodBeginReadBegins an asynchronous read operation. (Consider using System.IO.Stream.ReadAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream)
    Public MethodBeginWriteBegins an asynchronous write operation. (Consider using System.IO.Stream.WriteAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream)
    Public MethodCloneOverridden. Creates a copy of the current OracleBFile object associated with the same physical file as the original.  
    Public MethodCloseOverridden. Closes the current stream and releases any resources associated with it.  
    Public MethodCloseFileCloses the physical file associated with the OracleBFile object opened before by OpenFile method.  
    Public MethodCopyToOverloaded. Copies data from the OracleBFile to a destination OracleLob.  
    Public MethodCopyToAsyncOverloaded. Asynchronously reads the bytes from the current stream and writes them to another stream. (Inherited from System.IO.Stream)
    Public MethodCreateObjRefCreates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from System.MarshalByRefObject)
    Public MethodDisposeDisposes the resources allocated by the OracleLob object. (Inherited from Devart.Data.Oracle.OracleLob)
    Public MethodEndBatchAllows server-side triggers to resume firing after performing multiple write operations. (Inherited from Devart.Data.Oracle.OracleLob)
    Public MethodEndReadWaits for the pending asynchronous read to complete. (Consider using System.IO.Stream.ReadAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream)
    Public MethodEndWriteEnds an asynchronous write operation. (Consider using System.IO.Stream.WriteAsync(System.Byte[],System.Int32,System.Int32) instead.) (Inherited from System.IO.Stream)
    Public MethodEraseOverloaded. Erases all data from the OracleLob. (Inherited from Devart.Data.Oracle.OracleLob)
    Public MethodFlushFlush/write all buffers for the current OracleLob. (Inherited from Devart.Data.Oracle.OracleLob)
    Public MethodFlushAsyncOverloaded. Asynchronously clears all buffers for this stream and causes any buffered data to be written to the underlying device. (Inherited from System.IO.Stream)
    Public MethodGetLifetimeServiceRetrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from System.MarshalByRefObject)
    Public MethodInitializeLifetimeServiceObtains a lifetime service object to control the lifetime policy for this instance. (Inherited from System.MarshalByRefObject)
    Public MethodIsEqualDetermines whether the specified OracleLob object is equal to the current OracleLob. (Inherited from Devart.Data.Oracle.OracleLob)
    Public MethodOpenFileOpens the file with which an OracleBFile object is associated.  
    Public MethodReadOverloaded. Overridden. Reads a sequence of bytes from the current OracleBFile stream and advances the position within the stream by the number of bytes read.  
    Public MethodReadAsyncOverloaded. Asynchronously reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read. (Inherited from System.IO.Stream)
    Public MethodReadByteReads a byte from the stream and advances the position within the stream by one byte, or returns -1 if at the end of the stream. (Inherited from System.IO.Stream)
