如何在.NET中实现共享内存？

dotnet add package System.IO.MemoryMappedFiles

using System;
using System.IO.MemoryMappedFiles;

public class SharedMemory
{
    private MemoryMappedFile _mmf;
    private MemoryMappedViewAccessor _accessor;

    public void Create(string mapName, long size)
    {
        _mmf = MemoryMappedFile.CreateOrOpen(mapName, size);
        _accessor = _mmf.CreateViewAccessor();
    }

    public void Write(long offset, byte[] data)
    {
        _accessor.WriteArray(offset, data, 0, data.Length);
    }

    public byte[] Read(long offset, int size)
    {
        byte[] data = new byte[size];
        _accessor.ReadArray(offset, data, 0, size);
        return data;
    }

    public void Dispose()
    {
        _accessor.Dispose();
        _mmf.Dispose();
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        string mapName = "MySharedMemory";
        long size = 1000;

        using (var sharedMemory = new SharedMemory())
        {
            sharedMemory.Create(mapName, size);

            if (args.Length == 0)
            {
                // 写入数据
                byte[] data = new byte[] { 1, 2, 3 };
                sharedMemory.Write(0, data);
            }
            else
            {
                // 读取数据
                byte[] data = sharedMemory.Read(0, 3);
                Console.WriteLine($"Read from shared memory: {string.Join(", ", data)}");
            }
        }
    }
}
