The GetTotalMemory() method of GC class is used to get the total number of bytes currently thought to be allocated, this method accepts a Boolean parameter that represents whether this method should wait (for a short time) to allow the system to collect garbage & finalize objects.

Syntax:

    int GetTotalMemory(bool forceFullCollection);

Parameter(s):

  • forceFullCollection: It is a Boolean parameter, if it is set to true then method waits till occurrence of garbage collection.

Return value:

It returns allocated memory in bytes.

Program:

The source code to get the number of bytes currently thought to be allocated is given below. The given program is compiled and executed successfully.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Program pObj1 = new Program();
            Console.WriteLine("The generation of pObj1: " + GC.GetGeneration(pObj1));

            Program pObj2 = new Program();
            Console.WriteLine("The generation of pObj2: " + GC.GetGeneration(pObj2));

            Console.WriteLine("Total allocated memory: " + GC.GetTotalMemory(false));

            Console.WriteLine();
        }
    }
}

Output:

The generation of pObj1: 0
The generation of pObj2: 0
Total allocated memory: 62048
