Properties
CanWrite
When overridden in a derived class, gets a value indicating whether the current stream supports writing.
public override bool CanWrite { get; }
Property Value
Methods
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
intThe zero-based byte offset in
buffer
at which to begin storing the data read from the current stream.count
intThe 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
andcount
is larger than the buffer length.- ArgumentNullException
buffer
is null.- ArgumentOutOfRangeException
offset
orcount
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
longA byte offset relative to the
origin
parameter.origin
SeekOriginA 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
longThe 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。
