Memory Cleaner that forces GC to collect objects in asp.net or Wcf or Window service

The following example demonstrates how to use the Collect method to perform a collection on all generations of memory. The code generates a number of unused objects, and then calls the Collect method to clean them from memory.

[DllImportAttribute("Kernel32.dll", EntryPoint = "SetProcessWorkingSetSize", ExactSpelling = true, CharSet = CharSet.Ansi, SetLastError = true)]
    private static extern int ProcessWorkingSetSize(IntPtr Process, int minimumWorkingSetSize, int maximumWorkingSetSize);
    public void Flushmemory()
    {
        GC.Collect();
        GC.WaitForPendingFinalizers();
        if (Environment.OSVersion.Platform == PlatformID.Win32NT)
        {
            ProcessWorkingSetSize(System.Diagnostics.Process.GetCurrentProcess().Handle, -1, -1);
        }
    }
