当单元格打开并且单元格包含公式时，如何读取和优化单元格地址

Question

I have an excel file. This excel file contains a formula on a cell address(example A10). Now i open this excel file. One more thing I have installed an Add-Ins named Thomson Reuters in system. Through this Add-Ins cell address value changed periodically. How can i read the changed cell address value (without saving the excel file) using .net (c#).

You Just open your excel file using interop code this will allow addin code to run side by side. then you can use cell value using interop calls.

    Excel.Application xlApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
                    xlApp.Visible = true;
                    Excel.Workbook newWb = xlApp.Workbooks.Open(fileName, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
                                                                Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

xlApp.ActiveSheet.get_Range("A10", Type.Missing).Value2;
