General Info: Member Method

Also known as a Class Method.

A code routine that belongs to the class or an object instance (an instance of the class). Methods that belong to the class are called class methods or static methods. Methods that belong to an object instance are called instance methods, or simply methods.

When a method returns a value, it is a function method. When no value is returned (or void), it is a procedure method.

Methods frequently use method parameters to transfer data. When one object instance calls another object instance using a method with parameters, you call that messaging.

C# Member Method

In C#, you indicate a method with parens, no parens indicates a member property. Use the void return type for methods that do not return a value.

Syntax Example:

Define class:

public class Cyborg : System.Object
public virtual void IntroduceYourself()
MessageBox.Show("Hi, I do not have a name yet.");

Create object from class:

Cyborg T1 = new Cyborg();

A Simple Example

The following example uses our class above. Notice for the static�member, we do not use a variable, instead we use the class name directly. That's why static members are sometimes referred to as class members. Static members belong to the class�and are referenced by the class name.

Note: The public member fields cyborgName and cyborgAge are used here for demonstration only. You normally want to make them private and access them via a member property. Also not that cyborgName and cyborgAge start with a lowercase "c" and SeriesID starts with an uppercase "S". The reason I did this is normally you would make use of read-write public member fields. You would make them private. It is common to make member fields lowercase and properities uppercase.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace CR_MemberFields
public partial class Form1 : Form
public Form1()
    private void button1_Click(object sender, EventArgs e)
//Read static member field BEFORE we create our object.
//Notice the use of the class name, not a variable.
MessageBox.Show("We will now build a series " + Cyborg.SeriesID + " robot.");
    Cyborg MyRobot = new Cyborg();
    MyRobot.cyborgName = "John";
MyRobot.cyborgAge = 34;
    MessageBox.Show("We created a " + MyRobot.cyborgAge + " year old robot named " + MyRobot.cyborgName + "."); 

//You cannot refer to static members using an instance reference.

//MessageBox.Show("A series " + MyRobot.SeriesID + " robot.");

//Use a type name instead.

MessageBox.Show("A series " + Cyborg.SeriesID + " robot.");

  public class Cyborg : System.Object
private string serialNumber = "A100";
    public string cyborgName; 
public int cyborgAge = 0;
    public static readonly int SeriesID = 100;
