Excel Interop - running a Macro from C#


I am programmatically accessing an Excel Workbook via C# using the Excel.Interop assembly.

The workbook contains a custom Macro.

Is there a way of programmatically running this Macro?

I've tried:
 Workbook.Run ("MacroName")
But, that requires 30 additional parameters?!

Many Thanks.

You can either fill all those parameters with System.Reflection.Missing.Value.

  excel.Run("YourMacroName", System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, ..., System.Reflection.Missing.Value);

or you can use reflection to invoke the Run method,

  excel.GetType().InvokeMember("Run", System.Reflection.BindingFlags.Default | System.Reflection.BindingFlags.InvokeMethod, null, excel, new object[] { "YourMacroName" });
