c# - How to best fetch a cell value from excel using VSTO? -


i trying cells excel csharp not sure what's best variable type read into.

if make variable string , cell value double parse error. if make variable double when cell string wont work.

here's code running:

 try  {         string = globals.sheet1.cells[7, 7].value;         double num;         if (i == null) return;          if (double.tryparse(i, out num))          {               .               .               .         } } catch (exception e) {        messagebox.show(e.tostring()); }
