Methods
  NameDescription
Public methodBeginRead (Inherited from Stream.)
Public methodBeginWrite (Inherited from Stream.)
Public methodClose
Closes the current stream and releases any resources (such as sockets and file handles) associated with the current stream. Instead of calling this method, ensure that the stream is properly disposed.
(Inherited from Stream.)
Public methodCloseAsync
Closes the GridFS stream.
Public methodCopyTo(Stream)
Reads the bytes from the current stream and writes them to another stream.
(Inherited from Stream.)
Public methodCopyTo(Stream, Int32)
Reads the bytes from the current stream and writes them to another stream, using a specified buffer size.
(Inherited from Stream.)
Public methodCopyToAsync(Stream)
Asynchronously reads the bytes from the current stream and writes them to another stream.
(Inherited from Stream.)
Public methodCopyToAsync(Stream, Int32)
Asynchronously reads the bytes from the current stream and writes them to another stream, using a specified buffer size.
(Inherited from Stream.)
Public methodCopyToAsync(Stream, Int32, CancellationToken)
Asynchronously reads the bytes from the current stream and writes them to another stream, using a specified buffer size and cancellation token.
(Inherited from Stream.)
Public methodCreateObjRef
Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.
(Inherited from MarshalByRefObject.)
Protected methodCreateWaitHandle Obsolete.
Allocates a WaitHandle object.
(Inherited from Stream.)
Public methodDispose
Releases all resources used by the Stream.
(Inherited from Stream.)
Protected methodDispose(Boolean)
Releases the unmanaged resources used by the Stream and optionally releases the managed resources.
(Inherited from Stream.)
Public methodEndRead (Inherited from Stream.)
Public methodEndWrite (Inherited from Stream.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodFlush
When overridden in a derived class, clears all buffers for this stream and causes any buffered data to be written to the underlying device.
(Inherited from Stream.)
Public methodFlushAsync
Asynchronously clears all buffers for this stream and causes any buffered data to be written to the underlying device.
(Inherited from Stream.)
Public methodFlushAsync(CancellationToken)
Asynchronously clears all buffers for this stream, causes any buffered data to be written to the underlying device, and monitors cancellation requests.
(Inherited from Stream.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetLifetimeService
Retrieves the current lifetime service object that controls the lifetime policy for this instance.
(Inherited from MarshalByRefObject.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodInitializeLifetimeService
Obtains a lifetime service object to control the lifetime policy for this instance.
(Inherited from MarshalByRefObject.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodMemberwiseClone(Boolean)
Creates a shallow copy of the current MarshalByRefObject object.
(Inherited from MarshalByRefObject.)
Protected methodObjectInvariant Obsolete.
Provides support for a Contract.
(Inherited from Stream.)
Public methodRead
When overridden in a derived class, reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read.
(Inherited from Stream.)
Public methodReadAsync(Byte, Int32, Int32)
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 Stream.)
Public methodReadAsync(Byte, Int32, Int32, CancellationToken)
Asynchronously reads a sequence of bytes from the current stream, advances the position within the stream by the number of bytes read, and monitors cancellation requests.
(Inherited from Stream.)
Public methodReadByte
Reads 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 Stream.)
Public methodSeek
When overridden in a derived class, sets the position within the current stream.
(Inherited from Stream.)
Public methodSetLength
When overridden in a derived class, sets the length of the current stream.
(Inherited from Stream.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Public methodWrite
When overridden in a derived class, writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written.
(Inherited from Stream.)
Public methodWriteAsync(Byte, Int32, Int32)
Asynchronously writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written.
(Inherited from Stream.)
Public methodWriteAsync(Byte, Int32, Int32, CancellationToken)
Asynchronously writes a sequence of bytes to the current stream, advances the current position within this stream by the number of bytes written, and monitors cancellation requests.
(Inherited from Stream.)
Public methodWriteByte
Writes a byte to the current position in the stream and advances the position within the stream by one byte.
(Inherited from Stream.)
