| Description | |
|
The MemoryStream class uses memory as a store for data, allowing direct access for reading and writing.
The whole memory stream (block) can be extracted into an array of bytes - likewise, it can be constructed from such an array.
Important : when constructing from an array of bytes, the capacity of the stream is fixed by the number of bytes stored.

| Seek | Moves the current position in the Memory Stream to the specified value |
| SetLength | Sets the length of the memory stream |
| ToArray | Extracts the current Memory Streaminto an Array of Bytes |
| Write | Write some or all of an Array of Bytes into the current memory Stream |
| WriteByte | Writes a Byte to the current position in the Memory Stream |
| WriteTo | Writes the complete current Memory Stream to another stream |
