I had tried the IList<double>, and it works fine if I send in a list that is
full of doubles,
Using something like mylist = map(float,range(10))
That was an awkwardness I wanted to avoid. I wanted to be able to pass in
mylist = range(10) just as easily.
My C# routine will accept the argument as an IList (no type), but I'm unable to
cast it afterwards.
I finally solved the problem by accepting an IList, copying it element my
element to a new list of the correct type. If a typecast is required, I assign
it to a temporary variable of the same type first, then cast the temporary
variable.
This is the function I use for my conversion of each element. I settled on
using the IronPython.Runtime.List instead of IList because that's what I'm
really passing in, but they seem to act exactly the same in this context.
static private double pToDouble(IronPython.Runtime.List pList, int
index)
{
string type = pList[index].GetType().FullName;
if (type == "System.Int32")
{
int tmp = (int)pList[index];
return (double)tmp;
}
else if (type == "System.Double")
{
return (double)pList[index];
}
else
throw (new ApplicationException("Can't convert Python list to
Double"));
}
It's a little clumsy, but I'd rather push this down into the C# where I can
hide it from my Python users.

Have you tried using IList<double> or IEnumerable<double> as
arguments? IronPython should then handle the conversion for you.
