Inheritance

System.Object

ZippedContentStream

Namespace: Syncfusion.Compression.Zip

Assembly: Syncfusion.Compression.Portable.dll

Syntax

public class ZippedContentStream : Stream

Constructors

ZippedContentStream(ZipArchive.CompressorCreator)

Initializes new instance of the stream.

Declaration

public ZippedContentStream(ZipArchive.CompressorCreator createCompressor)

Parameters

Type	Name	Description
ZipArchive.CompressorCreator	createCompressor

Properties

CanRead

Gets a value indicating whether the current stream supports reading. Read-only.

Declaration

public override bool CanRead { get; }

Property Value

Type
System.Boolean

CanSeek

Gets a value indicating whether the current stream supports seeking. Read-only.

Declaration

public override bool CanSeek { get; }

Property Value

Type
System.Boolean

CanWrite

Gets a value indicating whether the current stream supports writing. Read-only.

Declaration

public override bool CanWrite { get; }

Property Value

Type
System.Boolean

Crc32

Returns computed crc32 value. Read-only.

Declaration

public uint Crc32 { get; }

Property Value

Type
System.UInt32

Length

Gets the length in bytes of the stream. Read-only.

Declaration

public override long Length { get; }

Property Value

Type
System.Int64

Position

Gets or sets the position within the current stream. Read-only.

Declaration

public override long Position { get; set; }

Property Value

Type
System.Int64

UnzippedSize

Returns size of the unzipped data. Read-only.

Declaration

public long UnzippedSize { get; }

Property Value

Type
System.Int64

ZippedContent

This property returns stream with zipped content. It closes internal deflate stream, so you won't be able to write anything in int. Read-only.

Declaration

public Stream ZippedContent { get; }

Property Value

Type
System.IO.Stream

Methods

Flush()

Clears all buffers for this stream and causes any buffered data to be written to the underlying device.

Declaration

public override void Flush()

Read(Byte[], Int32, Int32)

Reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read.

Declaration

public override int Read(byte[] buffer, int offset, int count)

Parameters

Type	Name	Description
System.Byte[]	buffer	An array of bytes. When this method returns, the buffer contains the specified byte array with the values between offset and (offset + count - 1) replaced by the bytes read from the current source.
System.Int32	offset	The zero-based byte offset in buffer at which to begin storing the data read from the current stream.
System.Int32	count	The maximum number of bytes to be read from the current stream.

Returns

Type	Description
System.Int32	The total number of bytes read into the buffer. This can be less than the number of bytes requested if that many bytes are not currently available, or zero (0) if the end of the stream has been reached.

Seek(Int64, SeekOrigin)

Sets the position within the current stream.

Declaration

public override long Seek(long offset, SeekOrigin origin)

Parameters

Type	Name	Description
System.Int64	offset	A byte offset relative to the origin parameter.
System.IO.SeekOrigin	origin	A value of type SeekOrigin indicating the reference point used to obtain the new position.

Returns

Type	Description
System.Int64	The new position within the current stream.

SetLength(Int64)

Sets the length of the current stream.

Declaration

public override void SetLength(long value)

Parameters

Type	Name	Description
System.Int64	value	The desired length of the current stream in bytes.

Write(Byte[], Int32, Int32)

Writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written.

Declaration

public override void Write(byte[] buffer, int offset, int count)

Parameters

Type	Name	Description
System.Byte[]	buffer	An array of bytes. This method copies count bytes from buffer to the current stream.
System.Int32	offset	The zero-based byte offset in buffer at which to begin copying bytes to the current stream.
System.Int32	count	The number of bytes to be written to the current stream.
