#region Reading Data From Excel File
dynamic objExcel = AutomationFactory.CreateObject("Excel.Application");
//Open the Workbook Here
dynamic objExcelWorkBook =
objExcel.Workbooks.Open(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
+ "\\" + fileName);
//Read the Worksheet
dynamic objActiveWorkSheet = objExcelWorkBook.ActiveSheet();
//Cells to Read
dynamic objCell_1, objCell_2;
//Iterate through Cells
for (int count = 2; count < 300; count++)
{
objCell_1 = objActiveWorkSheet.Cells[count, 1];
objCell_2 = objActiveWorkSheet.Cells[count, 2];
populationData.Add
(
new PopulationClass()
{
StateName = objCell_1.Value,
Population = objCell_2.Value
