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);
