Syntax

public abstract class OperationStream : Stream, IDisposable

Properties

CanRead

Gets a value indicating whether the current stream supports reading.

Declaration

public override bool CanRead { get; }

Property Value

System.Boolean

Overrides

System.IO.Stream.CanRead

CanSeek

Gets a value indicating whether the current stream supports seeking.

Declaration

public override bool CanSeek { get; }

Property Value

System.Boolean

Overrides

System.IO.Stream.CanSeek

CanWrite

Gets a value indicating whether the current stream supports writing.

Declaration

public override bool CanWrite { get; }

Property Value

System.Boolean

Overrides

System.IO.Stream.CanWrite

HasFlushedFinalBlock

Gets a value which indicates whether the final buffer block has been written/read to/from the underlying stream.

Declaration

public bool HasFlushedFinalBlock { get; }

Property Value

System.Boolean true if the final block has been flushed or end of underlying stream is reached; otherwise, false.

Length

Gets the length in bytes of the stream.

Declaration

public override long Length { get; }

Property Value

System.Int64

Overrides

System.IO.Stream.Length

Position

Gets or sets the position within the current stream.

Declaration

public override long Position { get; set; }

Property Value

System.Int64

Overrides

System.IO.Stream.Position

TotalPlainCount

Gets value which specify total plain bytes count (not-compressed and not-encrypted).

Declaration

public long TotalPlainCount { get; }

Property Value

System.Int64

TotalTransformedCount

Gets value which specify total transformed bytes count (compressed or encrypted).

Declaration

public long TotalTransformedCount { get; }

Property Value

System.Int64

Methods

Dispose(Boolean)

Releases the unmanaged resources used by the Stream and optionally releases the managed resources.

Declaration

protected override void Dispose(bool disposing)

Parameters

System.Boolean disposing Value which indicates whether both managed and unmanaged resources (true) on only unmanaged resources (false) should be released.

Overrides

System.IO.Stream.Dispose(System.Boolean)

EnsureNotDisposed()

Ensure that current stream is not disposed.

Declaration

protected void EnsureNotDisposed()

Finalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Declaration

protected void Finalize()

Flush()

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

Declaration

public override void Flush()

Overrides

System.IO.Stream.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

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

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.

Overrides

System.IO.Stream.Read(System.Byte[], System.Int32, System.Int32)

Exceptions

System.NotSupportedException The StreamOperationMode associated with current OperationStream object does not match the underlying stream. For example, this exception is thrown when using Read with an underlying stream that is write only.

System.ArgumentOutOfRangeException The offset parameter is less than zero.-or- The count parameter is less than zero.

System.ArgumentException The sum of the count and offset parameters is larger than the length of the buffer.

Seek(Int64, SeekOrigin)

Sets the position within the current stream.

Declaration

public override long Seek(long offset, SeekOrigin origin)

Parameters

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

System.Int64 The new position within the current stream.

Overrides

System.IO.Stream.Seek(System.Int64, System.IO.SeekOrigin)

SetLength(Int64)

Sets the length of the current stream.

Declaration

public override void SetLength(long value)

Parameters

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

Overrides

System.IO.Stream.SetLength(System.Int64)

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

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.

Overrides

System.IO.Stream.Write(System.Byte[], System.Int32, System.Int32)

StreamExtensions.ReadExactly(Stream, Byte[], Int32, Int32)
