CloseHandle(IntPtr handle)抛异常

        [DllImport("Kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        public static extern bool CloseHandle(IntPtr handle);

        [DllImport("kernel32", EntryPoint = "GetLastError")]
        public static extern int GetLastError();

CloseHandle（）释放两次就会抛异常，用GetLastError()来捕获，如果返回3，〖3〗-系统找不到指定的路径。

解决办法：

CloseHandle(m_hSharedMemoryFile);
m_hSharedMemoryFile = IntPtr.Zero;
