|
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().
|
|
|
CrcCalculatorStream(Stream, Int64, Boolean, CRC32) |
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(), and the CRC32 instance to use.
|
|
|
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) | (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()()()() |
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 |
Returns the length of the underlying 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.) |
|
|
Position |
The getter for this property returns the total bytes read.
If you use the setter, it will throw
NotSupportedException.
(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) |
Seeking is not supported on this stream. This method always throws
NotSupportedException (Overrides Stream.Seek(Int64, SeekOrigin).) |
|
|
SetLength(Int64) |
This method always throws
NotSupportedException (Overrides Stream.SetLength(Int64).) |
|
|
ToString()()()() | (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.) |
RemarksThis 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.
