An workable solution is presented below using System; using System.Collections.Generic; using System.Linq; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { var invoiceDataList = new List<InvoiceData>(); //populating some data Enumerable .Range(1, 10) .ToList() .ForEach( i => invoiceDataList.Add(new InvoiceData { InvoiceId = i, InvoiceNumber = i + 10, InvoiceDate = DateTime.Now.AddDays(i), TotalAmount = i % 2 == 0 ? 20000 + i : 1000 + i, ReceivedAmount = i % 2 == 0 ? 1000 + i: 20000 + i }) ); //the program var InvoiceMasterList = new List<InvoiceMaster>(); invoiceDataList .ToList() .ForEach(i => { if (i.ReceivedAmount > i.TotalAmount) Console.WriteLine("You Have Entered More Amount Than Invoice Amount"); else InvoiceMasterList.Add(new InvoiceMaster { InvoiceId = i.InvoiceId, InvoiceNumber = i.InvoiceNumber, InvoiceDate = i.InvoiceDate, TotalAmount = i.TotalAmount, ReceivedAmount = i.ReceivedAmount }); }); } } public class InvoiceData { public int InvoiceId { get; set; } public int InvoiceNumber { get; set; } public DateTime InvoiceDate { get; set; } public int TotalAmount { get; set; } public int ReceivedAmount { get; set; } } public class InvoiceMaster { public int InvoiceId { get; set; } public int InvoiceNumber { get; set; } public DateTime InvoiceDate { get; set; } public int TotalAmount { get; set; } public int ReceivedAmount { get; set; } } } Hope this helps. -- Thanks & Regards, RNA Team Kasani007, if this helps please login to Mark As Answer. \| Alert Moderator
