C#和Python共享内存技术

 我这里做一个简单的示例

1.C#写入内存的方法，FileName是内存共享的名字 t是内存size

        public static void SaveGluePLYToMemory(string FileName, string msg){try{ long t = 100;// SetMemorySize(msg);// 100;//# 创建内存块，test1,其他语言利用这个内存块名字就能找到内存块。var mmf = MemoryMappedFile.CreateOrOpen(FileName, t, MemoryMappedFileAccess.ReadWrite);var viewAccessor = mmf.CreateViewAccessor(0, t);string s = msg;viewAccessor.WriteArray<byte>(0, System.Text.Encoding.Default.GetBytes(s), 0, s.Length); // MessageBox.Show("write ok");//GC.Collect();}catch (System.Exception s){MessageBox.Show(s.Message);}}

2.Python读取内存 filename分别为TireGlueing和FoamStick

import copy
import os
import sys
import open3d as o3d;
import numpy as np
import pip;
import mmapfrom multiprocessing import shared_memoryif __name__ == "__main__": print("version")print(sys.path)print(o3d.__version__)print(sys.version)print(sys.executable)print(pip.__version__)print(pip.__file__)print(sys.getwindowsversion())try:MemorySize = 100file_name1 = 'TireGlueing'#print(SHMEMSIZE)# python读取共享内存shmem1 = mmap.mmap(0, MemorySize, file_name1, mmap.ACCESS_READ)print(f"TireGlue = {shmem1.read(MemorySize).decode('ASCII')}")#MemorySize = int(shmem.read(MemorySize).decode('ASCII'))shmem1.close() file_name = 'FoamStick'print(MemorySize)# python读取共享内存shmem = mmap.mmap(0, MemorySize, file_name, mmap.ACCESS_READ)#print(shmem.read(MemorySize).decode('ASCII'))print(f"FoamStick = {shmem.read(MemorySize).decode('ASCII')}")shmem.close() except Exception as e:print(e)print('ok')print("version end")
