ButtonBase

,

which inherits the 

Control

 class. 

Button

 defines only one constructor, which is shown here:

public Button( )

This creates a button that has a default size and location within the window. It contains no 

description. Before a button can be used, it will need to be given a description by assigning 

a string to its 

Text

 property.

To specify the location of the button within the window, you must assign the 

coordinates of its upper-left corner to the 

Location

 property. The 

Location

 property is 

inherited from 

Control

 and defined like this:

public Point Location { get; set; }

The coordinates are contained within a 

Point

 structure, which is defined in the 

System.Drawing

namespace. It includes these two properties:

public int X { get; set; }

public int Y { get; set; }

Thus, to create a button that contains the description “Press Here” and is positioned at 

location 100, 200, use the following sequence:

Button MyButton = new Button();

MyButton.Text = "Press Here";

MyButton.Location = new Point(100, 200);

Adding a Button to a Form

After you have created a button, you must add it to a form. You do this by calling the 

Add( )

method on the collection of controls linked to that form. This collection is available through
