Does class members occupy memory?

.net, asp.net, c#, memory

Solution

Say we have the following class:

public class Person
{
   public string Name { get; set; }

   public Person(string name)
   {
        Name = name;
   }

   public string SayName()
   {
      string hello = "Hello! My name is ";
      return hello + name;
   }
}

Person p = new Person("John");
string yourName = p.SayName();

The `SayName()` function goes on the `Call Stack`, and the `Person p` object and it's properties (`Name`) will stay in memory until the `Garbage Collection` comes in and cleans it up.

In terms of memory, you should be more concerned with the instance fields (properties) of the object, the amount of objects you are dealing with, and if your object is some time of `Reader` or `Connection`. If your object is a `Reader` or `Connection` you need to consider a `using` statement.

Pseudo-code:

using(DatabaseConnection dbConn = new DatabaseConnection()
{
    // Process your calls and data
}
// The object is Disposable and it's resources are cleared

Problem

A class is composed normally of member variables & methods. When we create instance of a class, memory is allocated for member variables of a class. Does member methods also occupy memory? Where are these methods stored?
