When a dot-net application runs, it generates a large number of objects. It’s likely that some of those objects aren’t used by the programme at any one time. A garbage collector is a Small Routine or a Background Process Thread in the.NET Framework<\/a> that runs periodically and tries to identify which objects are not currently being used by the application and deallocates the memory of those objects.<\/p>\n

So, Garbage Collector is nothing more than a CLR functionality that allows us to clean up or delete unneeded managed objects. By cleaning or eliminating those useless managed objects, the memory is effectively reclaimed.<\/p>\n

\"garbage\"\/<\/p>\n

In garbage collections, Generations <\/strong>are just the factors that determine how long objects remain in the memory.
\n0 Generation (Zero):<\/strong> This generation contains objects that have a short lifespan, such as Temporary objects. In this generation, the trash collection operation is started regularly by the GC.
\n1 Generation (One):<\/strong> This generation serves as a buffer between items with short lives and those with extended lives.
\n2 Generation (Two):<\/strong> This generation stores long-lived objects, such as a static and global variables, that must be kept for a period of time. Things that are not collected in generation Zero are moved to generation 1 and are known as survivors; similarly, objects that are not collected in generation One are moved to generation 2 and remain in the same generation from there on.<\/p>\n

The following are some of the GC class’s methods:<\/h2>\n

GC.GetGeneration():<\/strong> This method returns the target object’s generation number. It just takes one parameter, which is the target object for which the generation number is needed.
\nusing System;
\npublic class Demo {
\n\tpublic static void Main(string[] args)
\n\t{
\n\t\tDemo obj = new Demo();
\n\t\tConsole.WriteLine(\"The generation number of object is: \"\t\t\t\t\t\t\t\t\t\t+ GC.GetGeneration(obj));
\n\t}
\n}<\/code><\/p>\n

Output:<\/strong>
\nThe generation number of object is: 0<\/strong>
\nGC.GetTotalMemory()<\/strong> The number of bytes allocated in the system is returned by this procedure. It only requires a single boolean parameter, true indicating that the procedure waits for garbage collection to complete before returning, and false indicating the reverse.
\nusing System;
\npublic class Demo {
\n\tpublic static void Main(string[] args)\t{
\n\t\tConsole.WriteLine(\"Total Memory:\" + GC.GetTotalMemory(false));
\n\t\tDemo obj = new Demo();
\n\t\tConsole.WriteLine(\"The generation number of object is: \"
\n\t\t+ GC.GetGeneration(obj));
\n\t\tConsole.WriteLine(\"Total Memory:\" + GC.GetTotalMemory(false));
\n\t}
\n}<\/code><\/p>\n

Output:
\nTotal Memory:4197120
\nThe generation number of object is: 0
\nTotal Memory:4204024<\/em><\/strong><\/p>\n

GC.Collect():<\/strong> This method can be used to force garbage collection in the system. Only one parameter is required for this method: the number of the oldest generation for which garbage collection is performed.<\/p>\n

using System;
\npublic class Demo {
\n\tpublic static void Main(string[] args)
\n\t{
\n\tGC.Collect(0);
\n\tConsole.WriteLine(\"Garbage Collection in Generation 0 is: \"
\n\t+ GC.CollectionCount(0));
\n\t}
\n}<\/code><\/p>\n

Output:
\nGarbage Collection in Generation 0 is: 1<\/em><\/strong><\/p>\n
