SqlConnection _con = new SqlConnection(@"Data Source=STKWX028\SQLEXPRESS;Initial Catalog=Library;Integrated Security=True");
string queryStr = "SELECT * FROM bookInfo";
DataSet ds = new DataSet();
SqlDataAdapter ad = new SqlDataAdapter(queryStr, _con);
ad.Fill(ds);
Microsoft.Office.Interop.Excel.Application excelApp = new Application();
if (excelApp == null)
{
lblMessage.Text = "Fail to export because there's no excel installation!";
}
Workbook workbook = excelApp.Workbooks.Add(Missing.Value);
Worksheet worksheet = (Worksheet)workbook.Worksheets[1];//get the sheet index
for (int row = 0; row < ds.Tables[0].Rows.Count;row++ )//write data to excel
