ipc使用Shared和全局MMF

使用MMF和C＃我在2个进程之间创建了一个共享内存。

我的目标是将其创建为全局说长度为4000字节并创建分区

所以Main proj是“MainProj”将启动MMF名为"$AppName$_sharedMMF"

那么“Debugger Proj”将访问"$AppName$_sharedMMF"因此访问者位置是：

 MainProj->Debugger : readAddr = 0 , writeAddr = 250 Debbugger->MainProj : reafAddr = 250, writeAddr = 0 

然后我解决方案中的第三个可执行文件将是

 //setter getter MainProj->AnotherExe : readAddr = 251 , writeAddr = 500 //setter getter EnotherExe->MainProj : reafAddr = 500, writeAddr = 251 

我面临的问题是，我希望mainProj成为MMF的全局实例

所以每次我想访问分区我都会使用相同的静态类和方法

 //accessed by main project SharedSetter(SelectedGetter, Data) 

1）因为它由多个线程共享它有点复杂，虽然添加分区并不像整个设置那样复杂，这是一个坏主意吗？

2）我是否真的不能跳过mmf的创建新实例步骤并将其保留为“Alive”并仅创建新的访问器？

3）是否有人实施了该方法？
