Using the following method you can convert the DataTable into a List

For example you have the following DataTable:

DataTable resultTable = ConvertToDataTableFromList(realTimeSalesInput.RealTimeSales);
DataTable salesDt = new DataTable("RealTimeSales");
salesDt.Columns.Add("StoreNumber", typeof(string));
salesDt.Columns.Add("Value", typeof(decimal));
    //Test Data
salesDt.Rows.Add(100, "A100", 100);
salesDt.Rows.Add(101, "B100", 101);
salesDt.Rows.Add(102, "C100", 102);

Now you can call the following function to provide the List from the given DataTable.

    /// <summary>
    /// RealTimeSales
    /// </summary>
    public class RealTimeSales
    {
        public long StoreID { get; set; }

        public string StoreNumber { get; set; }

        public decimal Value { get; set; }
    }

    List<RealTimeSales> salesList = new List<RealTimeSales>();
    salesList = ConvertToListFromDataTable<RealTimeSales>(salesDt);

        /// <summary>
        /// Converts to list from data table.
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="dt">The dt.</param>
        /// <returns></returns>
        public List<T> ConvertToListFromDataTable<T>(System.Data.DataTable dt)
        {
            System.Collections.Generic.List<T> data = new List<T>();
            foreach (System.Data.DataRow row in dt.Rows)
            {
                T item = GetItemValue<T>(row);
                data.Add(item);
            }
            return data;
        }

        /// <summary>
        /// Gets the item.
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="dr">The dr.</param>
        /// <returns></returns>
        public T GetItemValue<T>(System.Data.DataRow dr)
        {
            System.Type temp = typeof(T);
            T obj = Activator.CreateInstance<T>();

            foreach (DataColumn column in dr.Table.Columns)
            {
                foreach (System.Reflection.PropertyInfo pro in temp.GetProperties())
                {
                    if (pro.Name == column.ColumnName)
                        pro.SetValue(obj, dr[column.ColumnName], null);
                    else
                        continue;
                }
            }
            return obj;
        }
