C# Windows Forms Control Examples

Let us look at a simple C# Windows Forms Control example.

Example 1: Control

This example will comprise the following files:

• Control.cs

Step 1: Create Project

1. The first step is to create a C# Project.
2. Go to FILE-->New-->Project to create a new project.

Step 2: Write Code

Write Code as follows:

*(a). Control.cs

Create a file named Control.cs

Here is the full code

using System;
using System.Windows.Forms;

namespace Examples {
  class MainForm : Form {
    public static void Main() {
      Application.EnableVisualStyles();
      Application.Run(new MainForm());
    }

    public MainForm() {
      Text = "Control example";

      control1.Parent = this;
      control1.BackColor = System.Drawing.Color.SpringGreen;
      control1.Cursor = Cursors.Hand;
      control1.Location = new System.Drawing.Point(50, 50);
      control1.Size = new System.Drawing.Size(100, 50);
      control1.Click += delegate {
        control1.BackColor = control1.BackColor == System.Drawing.Color.SpringGreen ? System.Drawing.Color.OrangeRed : System.Drawing.Color.SpringGreen;
      };
    }

    private Control control1 = new Control();
  }
}
