C# interacting with Excel
-
Hello. I use C# in Visual Studio and need to work with Excels spreadsheets. I know how to create and save the spreadsheets, but I need to format the plan, like to define the cell color, a collumn width and so on. Can anyone tell me how to access the commands in Excel through C#? Thanks.

Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

You can use the Range[^] class to refer to rows, columns and cells. You can add formatting, formulas etc through these objects. I have a sample application that contains the following sequence to control a range of cells:
cellRange = worksheet.get_Range("D2", "D6"); // select some cells
cellRange.Formula = "=RAND()*100000"; // add a formula to each cell
cellRange.NumberFormat = "£#,##0.00"; // format the values as pounds sterlingThere are a number of websites run by Excel experts that offer help which Google can find for you.
