       private void button7_click(object sender, eventargs e) {     list<mycolumns> list = new list<mycolumns>();      openfiledialog openfile1 = new openfiledialog();     openfile1.multiselect = true;      if (openfile1.showdialog() != dialogresult.cancel)     {         foreach (string filename in openfile1.filenames)         {              using (streamreader sr = new streamreader(filename))             {                 string line;                 while ((line = sr.readline()) != null)                 {                     string[] _columns = line.split(",".tochararray());                     mycolumns mc = new mycolumns();                     mc.time = _columns[0];                     mc.system_description = _columns[1];                     mc.user_description = _columns[2];                     list.add(mc);                 }             }         }         datatable listasdatatable = builddatatable<mycolumns>(list);         dataview listasdataview = listasdatatable.defaultview;         this.datagridview1.datasource = view = listasdataview;         this.datagridview1.allowusertoaddrows = false;         datagridview1.clearselection();     }     textbox1.text = this.datagridview1.rows.count.tostring(); } 

   i thinking using reg expresions, format of text this. field1>(6)field2>(23)field3>(2)field4>(50+) field 3 spaces work delimiters, possible change them commas, while working text??

if fixed-width columns, 1 way using string.substring , trimming results each column string.trim.
