The CompressionStream type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|

Creates a new instance of CompressionStream class.
|
Methods
| Name | Description | |
|---|---|---|
| BeginRead | Begins an asynchronous read operation. (Inherited from Stream.) |
| BeginWrite | Begins an asynchronous write operation. (Inherited from Stream.) |
| Close | Closes the current stream and releases any resources (such as sockets and file handles) associated with the current stream. (Inherited from Stream.) |
| CopyTo(Stream) | (Inherited from Stream.) |
| CopyTo(Stream, Int32) | (Inherited from Stream.) |
| CopyToAsync(Stream) | (Inherited from Stream.) |
| CopyToAsync(Stream, Int32) | (Inherited from Stream.) |
| CopyToAsync(Stream, Int32, CancellationToken) | (Inherited from Stream.) |
| CreateObjRef | 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) |
Closes the underlying stream.
(Overrides Stream..::..Dispose(Boolean).) |
| EndRead | Waits for the pending asynchronous read to complete. (Inherited from Stream.) |
| EndWrite | Ends an asynchronous write operation. (Inherited from Stream.) |
| Equals | 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 |
Causes any buffered data to be written to the underlying stream.
(Overrides Stream..::..Flush()()()().) |
| FlushAsync()()()() | (Inherited from Stream.) |
| FlushAsync(CancellationToken) | (Inherited from Stream.) |
| 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.) |
| MemberwiseClone()()()() | Creates a shallow copy of the current Object. (Inherited from Object.) |
| MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
| ObjectInvariant | Obsolete. (Inherited from Stream.) |
| Read |
Reads data from the underlying stream, compressing them during the process.
(Overrides Stream..::..Read(array<Byte>[]()[][], Int32, Int32).) |
| ReadAsync(array<Byte>[]()[][], Int32, Int32) | (Inherited from Stream.) |
| ReadAsync(array<Byte>[]()[][], Int32, Int32, CancellationToken) | (Inherited from Stream.) |
| 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.) |
| Seek |
This method is not supported by the CompressionStream class.
(Overrides Stream..::..Seek(Int64, SeekOrigin).) |
| SetLength |
This method is not supported by the CompressionStream class.
(Overrides Stream..::..SetLength(Int64).) |
| ToString | Returns a String that represents the current Object. (Inherited from Object.) |
| Write |
Writes a sequence of bytes into the current stream. The sequence will be compressed and the result written
into the underlying stream.
(Overrides Stream..::..Write(array<Byte>[]()[][], Int32, Int32).) |
| WriteAsync(array<Byte>[]()[][], Int32, Int32) | (Inherited from Stream.) |
| WriteAsync(array<Byte>[]()[][], Int32, Int32, CancellationToken) | (Inherited from Stream.) |
| WriteByte | Writes a byte to the current position in the stream and advances the position within the stream by one byte. (Inherited from Stream.) |
Fields
| Name | Description | |
|---|---|---|
  | DefaultCompressionLevel |
The default compression level.

(Overrides Stream..::..Position.) |
| ReadTimeout | Gets or sets a value that determines how long the stream will attempt to read before timing out. (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.) |
