Read the text of the Cell instead of Value

Question

I am trying to write a program to compare two excel files in C#. I am able to open the files n read the value of the excel but i would like to compare the text in the Cell.

For example In my sheet, If the Cell A3 is having a formula say "=A1+A2". I am able to retrieve the value using

((Range)worksheet.Cells[2,0]).Value 

of A3(the total value of A1 and A2) but not "=A1+A2". How can i get the text.(.Text is always null)

Thanks you

Answer 1

Looks like the Formula property should have it.

Range.Formula Property

"If the cell contains a constant, this property returns the constant. If the cell is empty, this Formula property returns an empty string. If the cell contains a formula, the Formula property returns the formula as a string in the same format that would be displayed in the formula bar (including the equal sign)."

((Range)worksheet.Cells[2,0]).Formula;

Answer 2

try

((Range)worksheet.Cells[2,0]).Formula
