[landv]

内存共享读取

class Program
{
	static void Main()
	{
		// 打开一个现有的内存映射文件
		using (MemoryMappedFile mmf = MemoryMappedFile.OpenExisting("sharedMemory"))
		{
			// 创建一个视图流来访问内存映射文件
			using (MemoryMappedViewStream stream = mmf.CreateViewStream())
			{
				// 读取数据从内存映射文件
				byte[] data = new byte[1024];
				int bytesRead = stream.Read(data, 0, data.Length);
				string message = Encoding.UTF8.GetString(data, 0, bytesRead);
				Console.WriteLine("Data read from shared memory: " + message);
			}
		}

	}
}

内存共享写入

class Program
{
	static void Main()
	{
		// 创建或打开一个内存映射文件
		using (MemoryMappedFile mmf = MemoryMappedFile.CreateOrOpen("sharedMemory", 1024))
		{
			// 创建一个视图流来访问内存映射文件
			using (MemoryMappedViewStream stream = mmf.CreateViewStream())
			{
				// 写入数据到内存映射文件
				byte[] data = Encoding.UTF8.GetBytes("Hello from Process 1");
				stream.Write(data, 0, data.Length);
				Console.WriteLine("Data written to shared memory.");
			}
		}

		//Console.WriteLine("Press any key to exit...");
		//Console.ReadKey();
