The CheckBox control is the part of windows form which is used to take input from the user. Or in other words, CheckBox control allows us to select single or multiple elements from the given list. In CheckBox, you are allowed to set the horizontal and vertical alignment of the check mark on a CheckBox using the CheckAlign property of the CheckBox. The default value of this property is MiddleLeft. In Windows form, you can set this property in two different ways:1. Design-Time: It is the simplest way to set the CheckAlign property of a CheckBox using the following steps:  
Step 1: Create a windows form as shown in the below image: Visual Studio -> File -> New -> Project -> WindowsFormApp  
Step 2: Drag the CheckBox control from the ToolBox and drop it on the windows form. You can place CheckBox anywhere on the windows form according to your need.  
Step 3: After drag and drop you will go to the properties of the CheckBox control to set the alignment of the check mark in CheckBox by using CheckAlign property.  
Output:  
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the CheckAlign property of a CheckBox programmatically using the following syntax: 
public System.Drawing.ContentAlignment CheckAlign { get; set; }
Here, ContentAlignment is used to represent the ContentAlignment values. It will throw an InvalidEnumArgumentException if the value of this property is not according to the ContentAlignment values. Following steps are used to set the CheckAlign property of the CheckBox:  
Step 1: Create a checkbox using the CheckBox() constructor provided by the CheckBox class.  
// Creating checkbox
CheckBox Mycheckbox = new CheckBox();
Step 2: After creating CheckBox, set the CheckAlign property of the CheckBox provided by the CheckBox class.  
// Set the CheckAlign property of the CheckBox
Mycheckbox.CheckAlign = ContentAlignment.MiddleCenter;
Step 3 : And last add this checkbox control to form using Add() method.  
// Add this checkbox to form
this.Controls.Add(Mycheckbox);
Example: 
CSharp
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms; namespace WindowsFormsApp5 { public partial class Form1 : Form {     public Form1()    {        InitializeComponent();    }     private void Form1_Load(object sender, EventArgs e)    {         // Creating and setting the properties of label        Label l = new Label();        l.Text = "Select city:";        l.Location = new Point(233, 111);         // Adding label to form        this.Controls.Add(l);         // Creating and setting the properties of CheckBox        CheckBox Mycheckbox = new CheckBox();        Mycheckbox.Height = 50;        Mycheckbox.Width = 100;        Mycheckbox.Location = new Point(229, 136);        Mycheckbox.Text = "Jaipur";        Mycheckbox.CheckAlign = ContentAlignment.MiddleCenter;         // Adding checkbox to form        this.Controls.Add(Mycheckbox);         // Creating and setting the properties of CheckBox        CheckBox Mycheckbox1 = new CheckBox();        Mycheckbox1.Height = 50;        Mycheckbox1.Width = 100;        Mycheckbox1.Location = new Point(230, 174);        Mycheckbox1.Text = "Mumbai";        Mycheckbox1.CheckAlign = ContentAlignment.MiddleCenter;         // Adding checkbox to form        this.Controls.Add(Mycheckbox1);    }}}
