How do I use Memory Stream in C#

This code shows how to use MemoryStream class and its member to read data in memory stream, which can be used to save it from there.

using System;
using
System.IO;
using
System.Text;
class
MemoryStreamSample
{
static void
Main()
{
int
count;
//GetByteData function to get Byte data like if you fetch Image column data from sqlserver or somewhere.
byte
[] byteArray = getByteData();
MemoryStream memStream =
new
MemoryStream(ByteArray);
// Write the second string to the stream, byte by byte.
count = 0;
// Write the stream properties to the console.
Console.WriteLine(
"Capacity = {0}, Length = {1}, Position = {2}\n",
memStream.Capacity.ToString(),
memStream.Length.ToString(),
memStream.Position.ToString());
// Set the position to the beginning of the stream.
memStream.Seek(0, SeekOrigin.Begin);
// Read the first 20 bytes from the stream.
byteArray = new byte
[memStream.Length];
count = memStream.Read(byteArray, 0, 20);
// Read the remaining bytes, byte by byte.
while
(count < memStream.Length)
{
byteArray[count++] = Convert.ToByte(memStream.ReadByte());
}
// Decode the byte array into a char array
// and write it to the console.
charArray = new char
[uniEncoding.GetCharCount(byteArray, 0, count)];
uniEncoding.GetDecoder().GetChars(byteArray, 0, count, charArray, 0);
Console.WriteLine(charArray);
}
}
