How to convert a .Net array into something Matlab can understand?

I have managed to write some .net code and compile it to a dll, and call it successfully from Matlab.

The resulting object exposes a number of properties which are all array of string/double/DateTime.

If I do the following in Matlab

z = Library1.DbData.getData(startDt, endDt);
a = cell(z.a_text_field);

Then I can see the results in a no problem.

However, if I do

c = cell(z.dates,'ConvertTypes','System.DateTime');

Then I get

Error using cell
Conversion to double from System.DateTime[] is not possible.

And if I do

d = cell(z.doubles,'ConvertTypes','all');

Then I get

Error using cell
Size inputs must be scalar.

I could hack this and make everything return a stirng, but it seems a bit ugly. How can I make doubles and datetimes work?

I have answer for the double array. I simply need to do

x = z.some_numeric_field.double;

There doesn't seem to be any equivalent for DateTime though.

Final update: for DateTime I am just returning the Matlab date number instead of a DateTime. Slighlty hacky. Better support for primitave arrays would be nice.
