You can map Data Table to model class using a Generic class like below.

Generic class

 public static class DataTableMappingtoModel
    {
        /// 

        /// Maps Data Table values to coresponded model propertise
        /// 
        /// 
        /// 
        /// 
        public static List MappingToEntity(this DataTable dt) 
        {
            try
            {
                var lst = new List();
                var tClass = typeof (T);
                PropertyInfo[] proInModel = tClass.GetProperties();
                List proInDataColumns = dt.Columns.Cast().ToList();
                T cn;
                foreach (DataRow item in dt.Rows)
                {
                    cn = (T) Activator.CreateInstance(tClass);
                    foreach (var pc in proInModel)
                    {


                            var d = proInDataColumns.Find(c => string.Equals(c.ColumnName.ToLower().Trim(), pc.Name.ToLower().Trim(), StringComparison.CurrentCultureIgnoreCase));
                            if (d != null)
                                pc.SetValue(cn, item[pc.Name], null);


                    }
                    lst.Add(cn);
                }
                return lst;
            }
            catch (Exception e)
            {
                throw e;
            }
        }
    }

Model class

public class Item
{
    public string ItemCode { get; set; }
    public string Cost { get; set; }
    public override string ToString()
    {
        return "ItemCode : " + ItemCode + ", Cost : " + Cost;
    }
}

Create DataTable

public DataTable getTable()
{
    DataTable dt = new DataTable();
    dt.Columns.Add(new DataColumn("ItemCode", typeof(string)));
    dt.Columns.Add(new DataColumn("Cost", typeof(string)));
    DataRow dr;
    for (int i = 0; i < 10; i++)
    {
        dr = dt.NewRow();
        dr[0] = "ItemCode" + (i + 1);
        dr[1] = "Cost" + (i + 1);
        dt.Rows.Add(dr);
    }
    return dt;
}

Now we can convert this DataTable to List like below:

DataTable dt = getTable();
List lst = dt.ToCollection();
foreach (Item cn in lst)
{
    Response.Write(cn.ToString() + "
");
}

Hope will help you
