Optional parameter to COM components

dotnet interop: Some functions of COM components have optional parameters. When imported
into C#, the generated functions assume all parameters to be present. Is
there any way to call COM functions with optional functions? Thanks in
advance.

Assuming an optional second parameter

using System.Reflection

object optParam = System.Reflection.Missing.Value;
double required = 1.0;

someCall(required, optParam);
