DateTime is a struct. You have to pass a value. It should not take null.  If you tried to do that in c# it would not allow it either.

I am sure there is a really simple answer to this one… but so far it is eluding me.

 

I have a class something like this:

 

public class Foo

{

  …

    public int process_date(DateTime? mydate)

   {

      …

   }

}

 

 

I want to call this from python using pythondotnet.

 

 

Calling it like this works fine:

 

     mydate = DateTime(0)

     Foo().process_date(mydate)

 

But if I try to pass in a null as the date as follows:

 

    Foo().process_date(None)

 

I get:

 

   TypeError: No method matches given arguments

 

Hoping there is something really obvious I am missing here.
