How to get the selected values ​​from a CheckedListBox in c#

Question

I come with a question since I have no idea how to capture the data stored in the following checkedlistbox, which in this example is made up of 6 options to be able to check, in reality there are like 20, each selection option is a field in a table that allows null values ​​or default the selected option.

How could or how should I be able to capture this data to store it in a temporary variable and later in a method to be able to save the corresponding selection.

I thank you in advance for your help.

Hi @Roberto Carlos Espinosa ， Welcome to Microsoft Q&A,

You can use foreach to iterate through all items in the checklistbox to get them.

You can also traverse the checked items to get the checked items.

Then you can save them where you want:

Here's an example of mine:

using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace _9_21_x
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //access all items
            List<string> values = new List<string>();
            foreach (var item in checkedListBox1.Items)
            {
                values.Add(item.ToString());
            }
            Console.WriteLine("All items:");
            foreach (var item in values)
            {
                Console.WriteLine(item);
            }

            //access all checked items
            List<string> checkedValues = new List<string>();
            foreach (var item in checkedListBox1.CheckedItems)
            {
                checkedValues.Add(item.ToString());
            }
            Console.WriteLine("All checked items:");
            foreach (var item in checkedValues)
            {
                Console.WriteLine(item);
            }

        }
    }
}

Best Regards,
