So for this article first we will create a new windows application and add the below mention controls on form.

Now on button control click event add the below code.

C#.Net

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 WindowsFormsApplication2 {     public partial class Form1 : Form     {         public Form1()         {             InitializeComponent();         }         private void button1_Click(object sender, EventArgs e)         {             FontFamily fontFamily = new FontFamily("Arial");             int fontSize = Convert.ToInt32(ddlFontSize.SelectedItem);             Font font = new Font(fontFamily, fontSize, FontStyle.Regular, GraphicsUnit.Pixel);             label1.Font = font;         }     } }

VB.Net

Imports System.Collections.Generic Imports System.ComponentModel Imports System.Data Imports System.Drawing Imports System.Linq Imports System.Text Imports System.Windows.Forms Namespace WindowsFormsApplication2        Public Partial Class Form1               Inherits Form               Public Sub New()                      InitializeComponent()               End Sub               Private Sub button1_Click(sender As Object, e As EventArgs)                      Dim fontFamily As New FontFamily("Arial")                      Dim fontSize As Integer = Convert.ToInt32(ddlFontSize.SelectedItem)                      Dim font As New Font(fontFamily, fontSize, FontStyle.Regular, GraphicsUnit.Pixel)                      label1.Font = font               End Sub        End Class End Namespace

In above code I have first assign the font and after that I have taken the font size from dropdown list. Now we have done run the application and check the output.
