How to set the name of the CheckBox in C#?

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 assign a name to the CheckBox using the Name property of the CheckBox. It makes your CheckBox more attractive. In Windows form, you can set this property in two different ways:

1. Design-Time: It is the simplest way to set the Name 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 name of the CheckBox using Name property. 

Output:

2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the Name property of a CheckBox programmatically using the following syntax:

public string Name { get; set; }

Here, the name of the CheckBox is of string type. Following steps are used to set the Name 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 Name property of the CheckBox provided by the CheckBox class. 

// Set the Name property of the CheckBox
Mycheckbox.Name = "First_Check_Box";

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

// Add this checkbox to form
this.Controls.Add(Mycheckbox);

Example:

C#

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 language:";
        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 = "C#";
        Mycheckbox.BackColor = Color.LightPink;
        Mycheckbox.ForeColor = Color.DarkGreen;
        Mycheckbox.Name = "First_Check_Box";

        // 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(250, 198);
        Mycheckbox1.Text = "Ruby";
        Mycheckbox1.BackColor = Color.LightGreen;
        Mycheckbox1.ForeColor = Color.DeepPink;
        Mycheckbox1.Name = "Second_Check_Box";
        // Adding checkbox to form
        this.Controls.Add(Mycheckbox1);
    }
}
}
