More in hope than expectation as I am only skimming VSTO at the present (and
even then in VB.Net not C#), but if you have a pointer to the Excel
application object through the Office Interop structure then you should be
able to use the WorksheetFunction property of the Application object

xlApp.WorksheetFunction.Min(Range)

Note: Some functions are not available through this route for a list check
help in VBA for the property
