That's what I thought too... but..
In [82]: System.Nullable[System.DateTime]()

Thanks Brad.
I think I understand what is happening now. Note that the C# code I posted
works fine, you can pass in Null as mydate.
DateTime? mydate
Gets translated by the C# compiler to System.Nullable mydate.
When you pass in null to the method C# sets up a Nullable with the
HasValue set
Try System.Nullable[System.DateTime]()
I haven't tested that, but I think that's what you need.

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.

Thanks. At least on my system there is no such thing as System.Null
In c# at least, null is just a keyword in the language.

I believe you want to import System and pass System.Null. I can't remember if
I've done this, but I think so.

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 work
