 | Memory |
An efficient memory stream implementation that sacrifices the ability to
get access to the internal byte buffer in order to drastically improve
performance.

(Overrides StreamCanSeek) |
| CanTimeout |
Check whether or not reading and writing to the stream can timeout.
(Overrides StreamCanTimeout) |
| CanWrite |
Check whether or not the stream supports writing.
(Overrides StreamCanWrite) |
| Length |

Read a sequence of bytes from the stream and advances the position
within the stream by the number of bytes read.
(Overrides StreamRead(Byte, Int32, Int32)) |
| ReadAsync(Byte, Int32, Int32) | (Inherited from Stream) |
| ReadAsync(Byte, Int32, Int32, CancellationToken) |
Asynchronously read a sequence of bytes from the stream and advances the position
within the stream by the number of bytes read.
(Overrides StreamReadAsync(Byte, Int32, Int32, CancellationToken)) |
| ReadByte | (Inherited from Stream) |
| Seek |
Set the position within the current stream.
(Overrides StreamSeek(Int64, SeekOrigin)) |
| SetLength |
Set the length of the stream.
(Overrides StreamSetLength(Int64)) |
| ToArray | Copy the memory stream into a byte array. |
| ToString | (Inherited from Object) |
| Write |
Write a sequence of bytes to the stream and advances the current
position within this stream by the number of bytes written.
(Overrides StreamWrite(Byte, Int32, Int32)) |
| WriteAsync(Byte, Int32, Int32) | (Inherited from Stream) |
| WriteAsync(Byte, Int32, Int32, CancellationToken) |
Asynchronously write a sequence of bytes to the stream and advances the current
position within this stream by the number of bytes written.
(Overrides StreamWriteAsync(Byte, Int32, Int32, CancellationToken)) |
| WriteByte | (Inherited from Stream) |
Remarks
Instead of resizing an internal byte array, the MemoryBlockStream
chains blocks of non-contiguous memory. This helps improve performance by avoiding
unneeded copying of data from the old array to the newly allocated array as well
as the zeroing of the newly allocated array.
