C# 碎片内存Ipc在控制台上触发EventHandler,在Wpf应用程序上失败
我正在练习将MMF实现为IPC,我已经通过wpf作为监听器进行了尝试,并设置了触发MMF的事件处理程序 现在,我已经将相同的setter代码移动到Wpf应用程序上的Wpf(在那之前,setter是控制台应用程序)中,我无法启动事件处理程序 我已经成功地实现了,我不确定这个实现是否正确,…我唯一能确定的是它发送数据、接收回复(实际上来自wpf)并触发事件(在控制台上) MMF类C# 碎片内存Ipc在控制台上触发EventHandler,在Wpf应用程序上失败,c#,wpf,event-handling,ipc,shared-memory,C#,Wpf,Event Handling,Ipc,Shared Memory,我正在练习将MMF实现为IPC,我已经通过wpf作为监听器进行了尝试,并设置了触发MMF的事件处理程序 现在,我已经将相同的setter代码移动到Wpf应用程序上的Wpf(在那之前,setter是控制台应用程序)中,我无法启动事件处理程序 我已经成功地实现了,我不确定这个实现是否正确,…我唯一能确定的是它发送数据、接收回复(实际上来自wpf)并触发事件(在控制台上) MMF类 public class MMFDepositT //: DiposiT<MyData> { pri
