using system; using system.collections.generic; using system.componentmodel; using system.data; using system.drawing; using system.io; using system.linq; using system.text; using system.windows.forms;  namespace sts_converter {     public partial class form1 : form     {         public form1()         {             initializecomponent();         }          private void select_click(object sender, eventargs e)         {             int size = -1;             dialogresult result = openfiledialog1.showdialog(); // show dialog.             if (result == dialogresult.ok) // test result.             {                 string file = openfiledialog1.filename;                 try                 {                     string text = file.readalltext(file);                     size = text.length;                 }                 catch (ioexception)                 {                 }             }             console.writeline(size); // <-- shows file size in debugging mode.             console.writeline(result); // <-- debugging use only.         }      } }

it easy as:

string file = openfiledialog1.filename; file.writealllines(     file,      file.readlines(file).take(28).toarray() );
