Question

What is the difference between these two different ways to read a string from an Excel speadsheet while working with the Excel Interop in C#?

        String node1 = ((Excel.Range)ws.Cells[row, "A"]).Value2.ToString();
        String node1 = ws.Cells[row, "A"].ToString();

Is one better, more correct/through than the other?

Answer 1

It looks as though it has to do with Date and Currency data types.

The Value2 property, which you can use for the Range object, is
almost identical to the Value property except that the Value2 property
does not use the Currency and Date data types. Depending on how a cell
is formatted (for example, with date, currency, or other formats), the
two properties may return different values for the same cell.
