You'll need to create the workbook, add more sheets if needed (defaults with three), and then fill out the cells.

Top of the file:

using Excel=Microsoft.Office.Interop.Excel;

And then the main code for generating the Excel file

Excel.Application excel = new Application();

var workbook = (Excel._Workbook) (excel.Workbooks.Add(Missing.Value));

for (var i = 0; i < dataset.Tables.Count; i++)
{
    if (workbook.Sheets.Count <= i)
    {
        workbook.Sheets.Add(Type.Missing, Type.Missing, Type.Missing, 
                            Type.Missing);
    }

    var currentSheet = (Excel._Worksheet)workbook.Sheets[i];
    for (var y = 0; y < dataset.Tables[i].Rows.Count; y++)
    {
        for (var x = 0; x < dataset.Tables[i].Rows[y].ItemArray.Count(); x++)
        {
            currentSheet.Cells[y, x] = dataset.Tables[i].Rows[y].ItemArray[x];
        }
    }
}

workbook.SaveAs("C:\\Temp\\book.xlsx", Type.Missing, Type.Missing, Type.Missing,
                Type.Missing, Type.Missing, XlSaveAsAccessMode.xlNoChange, 
                Type.Missing, Type.Missing, Type.Missing, Type.Missing, 
                Type.Missing);

workbook.Close();
excel.Quit();

Response.WriteFile(C:\\Temp\\book.xlsx");

Don't know exactly if this will work, but it should get you in the right direction

(also: Type.Missing and Missing.Value come from the namespace System.Reflection, just FYI)
