Can we force garbage collector to run ?

System.GC.Collect() forces garbage collector to run. This is not recommended but can be used if situations arises.

using System;

class Program

    {

        private const int maxGarbage = 1000;

        static void Main()

        {

            // Put some objects in memory.

            Program.MakeSomeGarbage();

            Console.WriteLine("Memory used before collection: {0:N0}",

                              GC.GetTotalMemory(false));

 

            // Collect all generations of memory.

            GC.Collect();

            Console.WriteLine("Memory used after full collection: {0:N0}",

                              GC.GetTotalMemory(true));

            Console.ReadLine();

        }

        static void MakeSomeGarbage()

        {

            Version vt;

            // Create objects and release them to fill up memory with unused objects.

            for (int i = 0; i < maxGarbage; i++)

            {

                vt = new Version();

            }

        }     

}

 Output 

Memory used before collection:       193,252

Memoryused after full collection:   94,020
