Python与CSharp之间内存共享互传信息

C#写入字符串到共享内存

try

{

    long t = 1 << 10 << 10;

    var mmf = MemoryMappedFile.CreateOrOpen("test1", t, MemoryMappedFileAccess.ReadWrite);

    var viewAccessor = mmf.CreateViewAccessor(0, t);

    string s = "123";

    viewAccessor.Write(0, s.Length); ;

    viewAccessor.WriteArray<byte>(0, System.Text.Encoding.Default.GetBytes(s), 0, s.Length);

    // MessageBox.Show("write ok");

}

catch (System.Exception s)

{

    MessageBox.Show(s.Message);

}

Python从共享内存中读取

import mmap

str = '123'

byte = str.encode()

SHMEMSIZE = len(str)

file_name = 'test1'

print(SHMEMSIZE)

# python读取共享内存

shmem = mmap.mmap(0, SHMEMSIZE, file_name, mmap.ACCESS_READ)

print(shmem.read(SHMEMSIZE).decode('ASCII'))

shmem.close()

Python写入字符串到共享内存

import mmap

str = '123456'

byte = str.encode(encoding='UTF-8')

SHMEMSIZE = len(str)

file_name = 'global_share_memory'

print(file_name)

# python写入共享内存

shmem = mmap.mmap(0, SHMEMSIZE, file_name, mmap.ACCESS_WRITE)

shmem.write(byte)

while True:

    pass

C#从共享内存中读取

long capacity = 6;

var mmf = MemoryMappedFile.OpenExisting("global_share_memory");

MemoryMappedViewAccessor viewAccessor = mmf.CreateViewAccessor(0, capacity);

char[] charsInMMf = new char[6];

byte test = viewAccessor.ReadByte(0);

byte test2 = viewAccessor.ReadByte(1);

byte test3 = viewAccessor.ReadByte(2);

byte test4 = viewAccessor.ReadByte(3);
