this gives me data in xls file want add new column name "event" & need specific column xml want "name","address". how possible? please me on this...

after constructing data in data table. add new columns in data table following -

datacolumn namecol = datatable.columns.add("name", typeof(string)); namecol.allowdbnull = false;

reference : http://msdn.microsoft.com/en-us/library/hfx3s9wd(v=vs.110).aspx , put required data existing columns via loop or existing queries.
