Working with Checkbox in SharePoint

In below code we will see, how to add multichoice chekcbox field in list, add item with checkbox field and get value from chekcbox field.

using System;
using System.Collections.Specialized;
using Microsoft.SharePoint;

namespace ConsoleApp
    class Program
        static string listTitle = "My Custom List";
        static string fieldTitle = "Gift Options";
        static string fieldInternalName = null;

        static void Main(string[] args)
            using (SPSite site = new SPSite("http://localhost"))
                using (SPWeb web = site.RootWeb)
                    SPList list = web.Lists.TryGetList(listTitle);
                    if (list != null)
                        // Add a multichoice field to the list.
                        StringCollection choices = new StringCollection();
                        choices.Add("Gift wrap");
                        choices.Add("Gift card");
                        choices.Add("Include gift receipt");

                        fieldInternalName = list.Fields.Add(fieldTitle, SPFieldType.MultiChoice, false, false, choices);

                        // Get a reference to the field.
                        SPFieldMultiChoice choiceField = (SPFieldMultiChoice)list.Fields.GetField(fieldInternalName);

                        // Create a field value with all choices selected.
                        // (A CheckBoxChoiceField control would have all boxes checked.)
                        SPFieldMultiChoiceValue values = new SPFieldMultiChoiceValue();
                        foreach (string choice in choices)

                        // Add an item to the list.
                        SPListItem item = list.Items.Add();
                        item[SPBuiltInFieldId.Title] = "Test item";
                        item[choiceField.Id] = values;

                        // Get the value of the field in the item.
                        string rawValue = item[choiceField.Id].ToString();
                        SPFieldMultiChoiceValue typedValue = new SPFieldMultiChoiceValue(rawValue);

                        // Print the value.
                        Console.WriteLine("The raw value is {0}", rawValue);
                        Console.WriteLine("The value delimiter is {0}", SPFieldMultiChoiceValue.Delimiter);
                        for (int i = 0; i < typedValue.Count; i++)
                            Console.WriteLine("The value at index {0} is {1}", i, typedValue[i]);
            Console.WriteLine("\nPress ENTER to continue....");

Hope this helps!!!
