我正在尝试在我的应用程序（特别是Windows服务）中实现一个内存映射文件，然后使用C#表单从MMF中读取服务写入的内容。不幸的是，我似乎无法让表单从MMF中读取任何内容，更重要的是，表单似乎永远找不到服务创建的MMF。以下是概述我所做的内容的代码片段，有人能看出我做错了什么或者能够指导我更好的方向吗？
服务：
private MemoryMappedFile mmf = MemoryMappedFile.CreateOrOpen("AuditStream", 1024 * 1024);
private Mutex mutex = new Mutex(false, "MyMutex");
byte[] msg = new byte[1];
var view = mmf.CreateViewStream(0, 1);
byte[] rmsg = new byte[1];
for (int i = 0; i < 400; i++)
{
mutex.WaitOne();
for (int j = 0; j < msg.Length; j++)
{
msg[j] = (byte)i;
}
view.Position = 0;
view.Write(msg, 0, bufferSize);
//the next 3 lines verify that i wrote to the mmf and can potentially read from it
//These are just for testing
view.Position = 0;
view.Read(rmsg, 0, 1);
Log.Error("Finished MMF", rmsg[0].ToString());
mutex.ReleaseMutex();
}
表单：
private MemoryMappedFile mmf;
private Mutex mutex;
Thread t = new Thread(MmfMonitor);
t.Start();
private void MmfMonitor()
{
byte[] message = new byte[1];
while(!quit)
{
try
{
**mmf = MemoryMappedFile.OpenExisting("AuditStream");**
mutex = Mutex.OpenExisting("MyMutex");
var view = mmf.CreateViewStream(0, 1);
mutex.WaitOne();
view.Position = 0;
view.Read(message, 0, 1);
Invoke(new UpdateLabelCallback(UpdateLabel), message[0].ToString());
mutex.ReleaseMutex();
}catch(FileNotFoundException)
{
**//The AuditStream MMF is never found, and therefore doesnt every see the proper values**
}
}
}
此外，在服务“运行”时，MMF 应始终具有句柄，并且不应被垃圾回收器收回；
