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

true if the stream supports reading; otherwise, false.

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

true if the stream supports seeking; otherwise, false.

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

true if the stream supports writing; otherwise, false.

Length

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

public override long Length { get; }

Property Value

long

A long value representing the length of the stream in bytes.

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.

NotSupportedException

不支持获取此音频流的长度。

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

The current position within the stream.

Exceptions

IOException

An I/O error occurs.

NotSupportedException

The stream does not support seeking.

ObjectDisposedException

Methods were called after the stream was closed.

NotSupportedException

不支持获取或设置此音频流的位置。

Methods

Clear()

清空该流.

public void Clear()

Remarks

此操作会导致丢失所有缓冲的数据。

ClearAsync(CancellationToken)

清空该流.

public virtual Task ClearAsync(CancellationToken cancellationToken)

Parameters

cancellationToken CancellationToken

用于取消该异步操作的取消令牌。

Returns

Task

一个清空操作的异步任务。

Remarks

此操作会导致丢失所有缓冲的数据。

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.

NotSupportedException

不支持读取此音频流。

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 SeekOrigin 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.

NotSupportedException

不支持在此音频流中进行定位操作。

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.

NotSupportedException

不支持为此音频流设置长度。

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

Write(byte[], int, int) was called after the stream was closed.

WriteHeader(ushort, uint, bool)

向流中写入一个头部信息。

public virtual void WriteHeader(ushort seq, uint timestamp, bool missed)

Parameters

seq ushort

头部的序列号。

timestamp uint

头部的时间戳。

missed bool

头部是否用于标识丢失的数据包。

Exceptions

InvalidOperationException

该流不接收头部信息。
