An example

  1. C# source code


The following example shows the source code of a Point class:

namespace Graphics


{

///

Class Point models a point in a two-dimensional plane.


///

public class Point
{

///

Instance variable x represents the point's


/// x-coordinate.

private int x;

///

Instance variable y represents the point's


/// y-coordinate.

private int y;

/// Property X represents the point's x-coordinate.


public int X
{
get { return x; }
set { x = value; }
}

/// Property Y represents the point's y-coordinate.


public int Y
{
get { return y; }
set { y = value; }
}

///

This constructor initializes the new Point to


/// (0,0).

public Point() : this(0,0) {}

///

This constructor initializes the new Point to


/// (
,
).

///
xor is the new Point's x-coordinate.

///
yor is the new Point's y-coordinate.

public Point(int xor, int yor) {
X = xor;
Y = yor;
}

///

This method changes the point's location to


/// the given coordinates.

///
xor is the new x-coordinate.

///
yor is the new y-coordinate.

///
public void Move(int xor, int yor) {
X = xor;
Y = yor;
}

///

This method changes the point's location by


/// the given x- and y-offsets.
/// For example:
///
/// Point p = new Point(3,5);
/// p.Translate(-1,3);
///

/// results in p's having the value (2,8).
///

///

///
xor is the relative x-offset.

///
yor is the relative y-offset.

///
public void Translate(int xor, int yor) {
X += xor;
Y += yor;
}

///

This method determines whether two Points have the same


/// location.

///
o is the object to be compared to the current object.
///

/// True if the Points have the same location and they have


/// the exact same type; otherwise, false.
///
///
public override bool Equals(object o) {
if (o == null) {
return false;
}

if (this == o) {


return true;
}

if (GetType() == o.GetType()) {


Point p = (Point)o;
return (X == p.X) && (Y == p.Y);
}
return false;
}

///

Report a point's location as a string.


/// A string representing a point's location, in the form (x,y),
/// without any leading, training, or embedded whitespace.

public override string ToString() {
return "(" + X + "," + Y + ")";
}

///

/// location.

///

///
p2 is the second Point to be compared.

/// True if the Points have the same location and they have

///
///
public static bool operator==(Point p1, Point p2) {
if ((object)p1 == null || (object)p2 == null) {
return false;
}

if (p1.GetType() == p2.GetType()) {


return (p1.X == p2.X) && (p1.Y == p2.Y);
}

return false;


}

///

Here is the output produced by one documentation generator when given the source code for class Point, shown above:




Point



Class Point models a point in a two-dimensional
plane.




Instance variable x represents the point's
x-coordinate.




Instance variable y represents the point's
y-coordinate.




This constructor initializes the new Point to
(0,0).




This constructor initializes the new Point to
(
,
).


xor is the new Point's x-coordinate.


yor is the new Point's y-coordinate.




This method changes the point's location to
the given coordinates.


xor is the new x-coordinate.


yor is the new y-coordinate.




name="M:Graphics.Point.Translate(System.Int32,System.Int32)">
This method changes the point's location by
the given x- and y-offsets.
For example:

Point p = new Point(3,5);
p.Translate(-1,3);

results in p's having the value (2,8).



xor is the relative x-offset.


yor is the relative y-offset.





This method determines whether two Points have the same
location.


o is the object to be compared to the current
object.


True if the Points have the same location and they have
the exact same type; otherwise, false.

cref="M:Graphics.Point.op_Equality(Graphics.Point,Graphics.Point)"/>
cref="M:Graphics.Point.op_Inequality(Graphics.Point,Graphics.Point)"/>



Report a point's location as a string.
A string representing a point's location, in the form
(x,y),
without any leading, training, or embedded whitespace.



name="M:Graphics.Point.op_Equality(Graphics.Point,Graphics.Point)">
This operator determines whether two Points have the
same
location.


p1 is the first Point to be compared.


p2 is the second Point to be compared.

True if the Points have the same location and they have
the exact same type; otherwise, false.


cref="M:Graphics.Point.op_Inequality(Graphics.Point,Graphics.Point)"/>


name="M:Graphics.Point.op_Inequality(Graphics.Point,Graphics.Point)">
This operator determines whether two Points have the
same
location.


p1 is the first Point to be compared.


p2 is the second Point to be compared.

True if the Points do not have the same location and
the
exact same type; otherwise, false.


cref="M:Graphics.Point.op_Equality(Graphics.Point,Graphics.Point)"/>



This is the entry point of the Point class testing
program.

This program tests each method and operator, and


is intended to be run after any non-trvial maintenance has
been performed on the Point class.




Property X represents the point's
x-coordinate.




Property Y represents the point's
y-coordinate.
