  System.IO.MemoryStream Class
 
 Description
Calling writeTextBlock 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. After writeTextBlock
 Syntax
Constructor Create ;
Constructor Create ( InitialCapacity : Integer );
Constructor Create ( Bytes : Array of Byte );
Constructor Create ( Bytes : Array of Byte; CanWrite : Boolean );
Constructor Create ( Bytes : Array of Byte; StartIndex : Integer; Count : Integer );
Constructor Create ( Bytes : Array of Byte; StartIndex : Integer; Count : Integer; CanWrite : Boolean );
Constructor Create ( Bytes : Array of Byte; StartIndex : Integer; Count : Integer; CanWrite : Boolean; CanGetBuffer : Boolean );
 Methods
Close  Close the current Memory stream
Read  Returns a block of bytes from the current position in the Memory Stream
ReadByte  Returns the next byte from the current position inthe Memory Stream
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

 Properties
CanRead  Boolean  Gets a value indicating whether the current stream supports reading.
CanSeek  Boplean  Gets a value indicating whether the current stream supports seeking.
CanWrite  Boolean  Gets a value indicating whether the current stream supports writing.
Capacity  Integer  Gets or sets the number of bytes allocated for this stream.
Length  Int64  Gets the length of the stream in bytes.
Position  Int64  Gets or sets the current position within the stream.
