c# - Parsing Tab delimited text files -

i have tab delimited file columns , rows example: rows might not have value columns. know "order" doesn't change third tab delimited thing column3 , on.

column1  column2  column3 .... column12 .... column34 ... column50 123  34 abc 234     def                                   as@ddd.com    true      45           nyc                         wwe@dsds.com  false       

now need read file not of columns important program. example need stuff values in column2, column12,column45

what approach suggest?

try following approach

static void main(string[] args) {     datatable datatable = new datatable();     streamreader streamreader = new streamreader(@"c:\temp\txt.txt");     char[] delimiter = new char[] { '\t' };     string[] columnheaders = streamreader.readline().split(delimiter);     foreach (string columnheader in columnheaders)     {         datatable.columns.add(columnheader); // i've added column headers here.     }      while (streamreader.peek() > 0)     {         datarow datarow = datatable.newrow();         datarow.itemarray = streamreader.readline().split(delimiter);         datatable.rows.add(datarow);     }      foreach (datarow row in datatable.rows)     {         console.writeline(""----row no: " + datatable.rows.indexof(row) + "----"");          foreach (datacolumn column in datatable.columns)         {             //check columns need             if (column.columnname == "column2" ||                  column.columnname == "column12" ||                 column.columnname == "column45")              {                 console.write(column.columnname);                 console.write(" ");                 console.writeline(row[column]);             }         }     }     console.readline(); }
