I am doing a project regarding Hotel Management System. In this project I am using ViewStates to store data within pages. Now I want to generate a Excel document(xls) by using the data stored in ViewState. I have stored the data into ViewState using Collections.

This is the code for the view state

protected Collection Restaurants
if (ViewState[ViewstateRestaurantName] != null)
object o = ViewState[ViewstateRestaurantName]
return (Collection)o
return null


ViewState[ViewstateRestaurantName] = value

And this is my Excel generation codes.

protected void Button1_Click(object sender, EventArgs e)
////RestaurantRequestDto restaurant = new RestaurantRequestDto()

Application xlapp = (Application)System.Runtime.InteropServices.Marshal.GetActiveObject("Application")
Workbook xlworkbook = (Workbook)xlapp.ActiveWorkbook
Worksheet xlworksheet = (Worksheet)xlworkbook.ActiveSheet

xlworkbook.SaveAs("csharp-Excel.xls", XlFileFormat.xlWorkbookNormal, XlSaveAsAccessMode.xlExclusive)
Range chart_range = xlworksheet.UsedRange
for (int i = 0 i < Restaurants.Count-1 i++)
for (int j = 0 j < 5 j++)
xlworksheet.Cells[i + Restaurants.Count, j + 1] = this.Restaurants.FirstOrDefault()


Your kind assistance will be appreciated.
Thanks in advance.

Not a question, not clear what help would you expect.
