how to read excel file with double values, into c#

OK, I give you a solution but it is not the best one

 object myConvertingObject = oSheet2.Cells.Cells[row, col] as Range ;
 double myConvertedObject = (Double)myConvertingObject;

tnx for your reply but , I could not do some mathematical operation on the value of each cell, because they are obj. would you please tell me how to convert those cell values to Double?

 

thanks
