using System;
using System.Data;

namespace DataTableMerge
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create the first DataTable
            DataTable table1 = new DataTable("Table1");
            table1.Columns.Add("ID", typeof(int));
            table1.Columns.Add("Name", typeof(string));
            table1.Rows.Add(1, "John");
            table1.Rows.Add(2, "Jane");

            // Create the second DataTable
            DataTable table2 = new DataTable("Table2");
            table2.Columns.Add("ID", typeof(int));
            table2.Columns.Add("Name", typeof(string));
            table2.Rows.Add(3, "Peter");
            table2.Rows.Add(4, "Susan");

            // Create the third DataTable
            DataTable table3 = new DataTable("Table3");
            table3.Columns.Add("ID", typeof(int));
            table3.Columns.Add("Name", typeof(string));
            table3.Rows.Add(5, "Mark");
            table3.Rows.Add(6, "Lucy");

            // Merging DataTable 2 into DataTable 1
            table1.Merge(table2);

            // Merging DataTable 3 into DataTable 1
            table1.Merge(table3);

            // Display merged table
            Console.WriteLine("Merged DataTable:");
            foreach (DataRow row in table1.Rows)
            {
                Console.WriteLine($"ID: {row["ID"]}, Name: {row["Name"]}");
            }
            Console.ReadLine();
