Start Excel add-in with C#

Question

Is it possible to start an Excel add-in (in my case statistiXL) and interact with it by using c#? The add-in opens a frame with some fields, that also should be accessible with c#.

Thanks.

Answer 1

You can do it using Excel Interop; be aware addins aren't loaded when starting Excel via interop so you need to do something like this:

var excel = new Application();
var workbook = excel.workbooks.Add(Type.Missing);
excel.RegisterXLL(pathToMyXll);
excel.ShowExcel();

This example should get you going; it's in VB, but the interop object names and the concept are the same.
