IconMemberDescription
CrcCalculatorStream(Stream)
The default constructor.

CrcCalculatorStream(Stream, Boolean)
The constructor allows the caller to specify how to handle the underlying stream at close.

CrcCalculatorStream(Stream, Int64)
A constructor allowing the specification of the length of the stream to read.

CrcCalculatorStream(Stream, Int64, Boolean)
A constructor allowing the specification of the length of the stream to read, as well as whether to keep the underlying stream open upon Close().

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
Indicates whether the stream supports reading.
(Overrides Stream.CanRead.)
CanSeek
Indicates whether the stream supports seeking.
(Overrides Stream.CanSeek.)
CanTimeout
Gets a value that determines whether the current stream can time out.
(Inherited from Stream.)
CanWrite
Indicates whether the stream supports writing.
(Overrides Stream.CanWrite.)
Close()()()()
Closes the stream.
(Overrides Stream.Close()()()().)
Crc
Provides the current CRC for all blocks slurped in.

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 try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Flush()()()()
Flush the stream.
(Overrides Stream.Flush()()()().)
GetHashCode()()()()
Serves as a hash function for a particular type.
(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.)
LeaveOpen
Indicates whether the underlying stream will be left open when the CrcCalculatorStream is Closed.

Length
Not implemented.
(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.)
Position
Not implemented.
(Overrides Stream.Position.)
Read(array<Byte>[]()[][], Int32, Int32)
Read from the stream
(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, in miliseconds, that determines how long the stream will attempt to read before timing out.
(Inherited from Stream.)
Seek(Int64, SeekOrigin)
Not implemented.
(Overrides Stream.Seek(Int64, SeekOrigin).)
SetLength(Int64)
Not implemented.
(Overrides Stream.SetLength(Int64).)
ToString()()()()
Returns a string that represents the current object.
(Inherited from Object.)
TotalBytesSlurped
Gets the total number of bytes run through the CRC32 calculator.

Write(array<Byte>[]()[][], Int32, Int32)
Write to the stream.
(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, in miliseconds, that determines how long the stream will attempt to write before timing out.
(Inherited from Stream.)
Remarks

This class can be used to verify the CRC of a ZipEntry when reading from a stream, or to calculate a CRC when writing to a stream. The stream should be used to either read, or write, but not both. If you intermix reads and writes, the results are not defined.

This class is intended primarily for use internally by the DotNetZip library.
