when i run this i get an error as

Input string was not in a correct format

Can any one help me in this

string cell3 = SketchWorkSheet.Cells[i, 3].ToString();
string cell4 = SketchWorkSheet.Cells[i, 4].ToString();

1) It will take time.   <code>-- what doesn't, if it is worth doing?</code>
2) It is some paid thing  <code>-- what isn't - if it does the job you want?</code>
