Hi,

I am trying to do something like this in my code to add values of excel cells

xlWorkSheet1.Cells[i, 5] = row[13].ToString() + row1[13].ToString();

But it is just writing the values side by side in one cell

Can anyone suggest me how can I add the values of excel cells using c#

Thanks
John

Hi,

You are concatenating two values. if row[13] and row1[13] is numeric value you need to cast before sum each other.

So simple dear.

Best luck :)

Hi,
I tried like this by using casting

xlWorkSheet1.Cells[i, 5] = Convert.ToInt32(row[13]) + Convert.ToInt32(row1[13]);
It is working fine, but giving integer values. But I have floating point values
I am trying like this
xlWorkSheet1.Cells[i, 5] = (float)(row[13]) + (float)(row1[13]);
which is not working

use Convert.ToDouble
