How to quickly release the memory of. NET programs

[DllImport ("kernel32.dll")]
Public static extern bool SetProcessWorkingSetSize (IntPtr process, int minSize, int maxSize );

Public static void GarbageCollect ()
{
GC. Collect ();
GC. WaitForPendingFinalizers ();
GC. Collect ();
}

Public static void FlushMemory ()
{
GarbageCollect ();

If (Environment. OSVersion. Platform = PlatformID. Win32NT)
{
Win32.SetProcessWorkingSetSize (System. Diagnostics. Process. GetCurrentProcess (). Handle,-1,-1 );
}
}



NET has a class to achieve this effect.
System. Diagnostics. Process. GetCurrentProcess (). MinWorkingSet = new System. IntPtr (5 );

It works well when the regular release + form is used for opening. It is estimated that the memory occupied by the program will be below 20
