title: Read specific columns from Excel files with C#
body: <p>I want to read some Excel files and convert to my own Excel template. I want to read B column every line (B1,B2,B3... going like this).</p>
  
  <p>If there is a number in this column; in B3 there is number like "1,2,3,4,5,6,7,8,9" then I'll get this whole line and take it to an array[i]. If there is "5" number in B4 then it'll get this whole line and take it to an array[i]. If there is no number in related line it will continue to next line.</p>
  
  <p>It will continue to read end of the Excel file. And I want to take this array and write to a new Excel file.</p>
