背景

多个进程直接需要传递大量图片，所以对性能要求较高。支付复制内存显然比转成byte[]再复制优越。

命名空间

using System;
using System.Diagnostics;
using System.Runtime.InteropServices;

代码

public CMainTestForm()
        {
            InitializeComponent();
            WriteIntToMemFile(34);
        }

        static unsafe void WriteIntToMemFile(int i)
        {
            using (var mmf = System.IO.MemoryMappedFiles.MemoryMappedFile.CreateNew("HZD20230925", 42))
            using (var view = mmf.CreateViewAccessor())
            {
                byte* poke = null;
                view.SafeMemoryMappedViewHandle.AcquirePointer(ref poke);
                CopyMemory(new System.IntPtr(poke), new System.IntPtr(&i), sizeof(int));
                view.SafeMemoryMappedViewHandle.AcquirePointer(ref poke);
                int iRead = view.ReadInt32(0);
                Debug.Assert(iRead == i);
            }
        }

[DllImport("kernel32.dll", EntryPoint = "RtlMoveMemory", CharSet = CharSet.Ansi)]
public extern static long CopyMemory(IntPtr dest, IntPtr source, int size);
