示例1: Main
// Note: you must compile this sample using the unsafe flag.
// From the command line, type the following: csc sample.cs /unsafe
using System;
using System.IO;
using System.Text;
using System.Runtime.InteropServices;
unsafe class TestWriter
{
static void Main()
{
// Create some data to read and write.
byte[] message = UnicodeEncoding.Unicode.GetBytes("Here is some data.");
// Allocate a block of unmanaged memory and return an IntPtr object.
IntPtr memIntPtr = Marshal.AllocHGlobal(message.Length);
// Get a byte pointer from the IntPtr object.
byte* memBytePtr = (byte*)memIntPtr.ToPointer();
// Create an UnmanagedMemoryStream object using a pointer to unmanaged memory.
UnmanagedMemoryStream writeStream = new UnmanagedMemoryStream(memBytePtr, message.Length, message.Length, FileAccess.Write);
// Write the data.
writeStream.Write(message, 0, message.Length);
// Close the stream.
writeStream.Close();
// Create another UnmanagedMemoryStream object using a pointer to unmanaged memory.
UnmanagedMemoryStream readStream = new UnmanagedMemoryStream(memBytePtr, message.Length, message.Length, FileAccess.Read);
// Create a byte array to hold data from unmanaged memory.
byte[] outMessage = new byte[message.Length];
// Read from unmanaged memory to the byte array.
readStream.Read(outMessage, 0, message.Length);
// Close the stream.
readStream.Close();
// Display the data to the console.
Console.WriteLine(UnicodeEncoding.Unicode.GetString(outMessage));
// Free the block of unmanaged memory.
Marshal.FreeHGlobal(memIntPtr);
Console.ReadLine();
