示例1: Main
//引入命名空间
using System;
using System.IO;
using System.Text;
class MemStream
{
static void Main()
{
int count;
byte[] byteArray;
char[] charArray;
UnicodeEncoding uniEncoding = new UnicodeEncoding();
// Create the data to write to the stream.
byte[] firstString = uniEncoding.GetBytes(
"Invalid file path characters are: ");
byte[] secondString = uniEncoding.GetBytes(
Path.GetInvalidPathChars());
using(MemoryStream memStream = new MemoryStream(100))
{
// Write the first string to the stream.
memStream.Write(firstString, 0 , firstString.Length);
// Write the second string to the stream, byte by byte.
count = 0;
while(count < secondString.Length)
{
memStream.WriteByte(secondString[count++]);
}
// 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);
}
}
}示例2: new MemoryStream()
//引入命名空间
using System;
using System.IO;
using System.Drawing;
using System.Drawing.Imaging;
public class Analyzer {
public static void Main() {
Image sample = new Bitmap("a.jpg");
MemoryStream buf = new MemoryStream();
sample.Save(buf, ImageFormat.Bmp);
byte[] currentImage = buf.GetBuffer();
int[] stats = new int[3];
for (int i = 0; i < currentImage.Length; ){
for (int j = 0; j < 3; j++) {
stats[j] += currentImage[i];
++i;
}
}
Console.WriteLine("Blue: " + stats[0]);
Console.WriteLine("Green: " + stats[1]);
Console.WriteLine("Red: " + stats[2]);
if ((stats[0] > stats[1]) && (stats[0] > stats[2]))
Console.WriteLine("This is a cold picture.");
if ((stats[1] > stats[0]) && (stats[1] > stats[2]))
Console.WriteLine("This is a summer picture.");
if ((stats[2] > stats[0]) && (stats[2] > stats[1]))
Console.WriteLine("This is a fiery picture.");
}
