Icon Member Description
DuplicateStream(Stream)
Creates a new duplicate of a stream.

BeginRead(array<Byte>[]()[], Int32, Int32, AsyncCallback, Object) HostProtectionAttribute.
Begins an asynchronous read operation.
(Inherited from Stream.)
BeginWrite(array<Byte>[]()[], Int32, Int32, AsyncCallback, Object) HostProtectionAttribute.
Begins an asynchronous write operation.
(Inherited from Stream.)
CanRead
Gets a value indicating whether the source stream supports reading.
(Overrides Stream.CanRead.)
CanSeek
Gets a value indicating whether the source stream supports seeking.
(Overrides Stream.CanSeek.)
CanTimeout
Gets a value that determines whether the current stream can time out.
(Inherited from Stream.)
CanWrite
Gets a value indicating whether the source stream supports writing.
(Overrides Stream.CanWrite.)
Close()()()
Closes the underlying stream, effectively closing ALL duplicates.
(Overrides Stream.Close()()().)
CreateObjRef(Type)
Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.
(Inherited from MarshalByRefObject.)
CreateWaitHandle()()() Obsolete.
Allocates a WaitHandle object.
(Inherited from Stream.)
Dispose()()()
Releases all resources used by the Stream.
(Inherited from Stream.)
Dispose(Boolean)
Releases the unmanaged resources used by the Stream and optionally releases the managed resources.
(Inherited from Stream.)
EndRead(IAsyncResult)
Waits for the pending asynchronous read to complete.
(Inherited from Stream.)
EndWrite(IAsyncResult)
Ends an asynchronous write operation.
(Inherited from Stream.)
Equals(Object)
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Finalize()()()
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
Flush()()()
Flushes the source stream.
(Overrides Stream.Flush()()().)
GetHashCode()()()
Serves as a hash function for a particular type. GetHashCode()()() is suitable for use in hashing algorithms and data structures like a hash table.
(Inherited from Object.)
GetLifetimeService()()()
Retrieves the current lifetime service object that controls the lifetime policy for this instance.
(Inherited from MarshalByRefObject.)
GetType()()()
Gets the Type of the current instance.
(Inherited from Object.)
InitializeLifetimeService()()()
Obtains a lifetime service object to control the lifetime policy for this instance.
(Inherited from MarshalByRefObject.)
Length
Gets the length of the source stream.
(Overrides Stream.Length.)
MemberwiseClone(Boolean)
Creates a shallow copy of the current MarshalByRefObject object.
(Inherited from MarshalByRefObject.)
MemberwiseClone()()()
Creates a shallow copy of the current Object.
(Inherited from Object.)
OriginalStream(Stream)
Retrieves the original stream from a possible duplicate stream.

Position
Gets or sets the position of the current stream, ignoring the position of the source stream.
(Overrides Stream.Position.)
Read(array<Byte>[]()[], Int32, Int32)
Reads from the source stream while maintaining a separate position and not impacting the source stream's position.
(Overrides Stream.Read(array<Byte>[]()[], Int32, Int32).)
ReadByte()()()
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.)
ReadTimeout
Gets or sets a value that determines how long the stream will attempt to read before timing out.
(Inherited from Stream.)
Seek(Int64, SeekOrigin)
Changes the position of this stream without impacting the source stream's position.
(Overrides Stream.Seek(Int64, SeekOrigin).)
SetLength(Int64)
Sets the length of the source stream.
(Overrides Stream.SetLength(Int64).)
Source
Gets the original stream that was used to create the duplicate.

ToString()()()
Returns a String that represents the current Object.
(Inherited from Object.)
Write(array<Byte>[]()[], Int32, Int32)
Writes to the source stream while maintaining a separate position and not impacting the source stream's position.
(Overrides Stream.Write(array<Byte>[]()[], Int32, Int32).)
WriteByte(Byte)
Writes a byte to the current position in the stream and advances the position within the stream by one byte.
(Inherited from Stream.)
WriteTimeout
Gets or sets a value that determines how long the stream will attempt to write before timing out.
(Inherited from Stream.)
Remarks
WARNING: duplicate streams are not thread-safe with respect to each other or the original stream. If multiple threads use duplicate copies of the same stream, they must synchronize for any operations.
