Constructors​

SKManagedStream(Stream, bool)​

public SKManagedStream(Stream stream, bool leaveOpen = false)

Parameters​

stream Stream

leaveOpen bool

Properties​

CanRead​

When overridden in a derived class, gets a value indicating whether the current stream supports reading.

public override bool CanRead { get; }

Property Value​

bool

CanSeek​

When overridden in a derived class, gets a value indicating whether the current stream supports seeking.

public override bool CanSeek { get; }

Property Value​

bool

CanWrite​

When overridden in a derived class, gets a value indicating whether the current stream supports writing.

public override bool CanWrite { get; }

Property Value​

bool

LeaveOpen​

public bool LeaveOpen { get; }

Property Value​

bool

Length​

When overridden in a derived class, gets the length in bytes of the stream.

public override long Length { get; }

Property Value​

long

Exceptions​

NotSupportedException

A class derived from Stream does not support seeking and the length is unknown.

ObjectDisposedException

Methods were called after the stream was closed.

Position​

When overridden in a derived class, gets or sets the position within the current stream.

public override long Position { get; set; }

Property Value​

long

Exceptions​

IOException

An I/O error occurs.

NotSupportedException

The stream does not support seeking.

ObjectDisposedException

Methods were called after the stream was closed.

Methods​

Dispose(bool)​

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

protected override void Dispose(bool disposing)

Parameters​

disposing bool

true to release both managed and unmanaged resources; false to release only unmanaged resources.

Flush()​

When overridden in a derived class, clears all buffers for this stream and causes any buffered data to be written to the underlying device.

public override void Flush()

Exceptions​

IOException

An I/O error occurs.

Read(byte[], int, int)​

When overridden in a derived class, reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read.

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

Parameters​

buffer byte[]

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.

offset int

The zero-based byte offset in buffer at which to begin storing the data read from the current stream.

count int

The maximum number of bytes to be read from the current stream.

Returns​

int

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 count is 0 or the end of the stream has been reached.

Exceptions​

ArgumentException

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

ArgumentNullException

buffer is null.

ArgumentOutOfRangeException

offset or count is negative.

IOException

An I/O error occurs.

NotSupportedException

The stream does not support reading.

ObjectDisposedException

Methods were called after the stream was closed.

Seek(long, SeekOrigin)​

When overridden in a derived class, sets the position within the current stream.

public override long Seek(long offset, SeekOrigin origin)

Parameters​

offset long

A byte offset relative to the origin parameter.

origin SeekOrigin

A value of type indicating the reference point used to obtain the new position.

Returns​

long

The new position within the current stream.

Exceptions​

IOException

An I/O error occurs.

NotSupportedException

The stream does not support seeking, such as if the stream is constructed from a pipe or console output.

ObjectDisposedException

Methods were called after the stream was closed.

SetLength(long)​

When overridden in a derived class, sets the length of the current stream.

public override void SetLength(long value)

Parameters​

value long

The desired length of the current stream in bytes.

Exceptions​

IOException

An I/O error occurs.

NotSupportedException

The stream does not support both writing and seeking, such as if the stream is constructed from a pipe or console output.

ObjectDisposedException

Methods were called after the stream was closed.

Write(byte[], int, int)​

When overridden in a derived class, writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written.

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

Parameters​

buffer byte[]

An array of bytes. This method copies count bytes from buffer to the current stream.

offset int

The zero-based byte offset in buffer at which to begin copying bytes to the current stream.

count int

The number of bytes to be written to the current stream.

Exceptions​

ArgumentException

The sum of offset and count is greater than the buffer length.

ArgumentNullException

buffer is null.

ArgumentOutOfRangeException

offset or count is negative.

IOException

An I/O error occurred, such as the specified file cannot be found.

NotSupportedException

The stream does not support writing.

ObjectDisposedException

was called after the stream was closed.
