A Button is an essential part of an application, or software, or webpage. It allows the user to interact with the application or software. For example, if a user wants to exit from the current application so, he/she click the exit button which closes the application. It can be used to perform many actions like to submit, upload, download, etc. according to the requirement of your program. It can be available with different shape, size, color, etc. and you can reuse them in different applications. In .NET Framework, Button class is used to represent windows button control and it is inherited from ButtonBase class. It is defined under System.Windows.Forms namespace.

In C# you can create a button on the windows form by using two different ways:

1. Design-Time: It is the easiest method to create a button. Use the below steps:

• Step 1: Create a windows form as shown in the below image:
  Visual Studio -> File -> New -> Project -> WindowsFormApp
  
• Step 2: Drag the Button control from the ToolBox and drop it on the windows form. You are allowed to place a Button control anywhere on the windows form according to your need.
  
• Step 3: After drag and drop you will go to the properties of the Button control to set the properties of the Button.
  

2. Run-Time: It is a little bit trickier than the above method. In this method, you can create your own Button using the Button class.

• Step 1: Create a button using the Button() constructor is provided by the Button class.

  // Creating Button using Button class
  Button MyButton = new Button();
  

• Step 2: After creating Button, set the properties of the Button provided by the Button class.

  // Set the location of the button
  Mybutton.Location = new Point(225, 198);
  
  // Set text inside the button
  Mybutton.Text = "Submit";
  
  // Set the AutoSize property of the button
   Mybutton.AutoSize = true;
  
  // Set the background color of the button
  Mybutton.BackColor = Color.LightBlue;
  
  // Set the padding of the button
  Mybutton.Padding = new Padding(6);
  
  // Set font of the text present in the button
  Mybutton.Font = new Font("French Script MT", 18);
  

• Step 3: And last add this button control to form using Add() method.

  // Add this Button to form
  this.Controls.Add(Mybutton);
