slice2cs 3.4.1 omits map types

Hi. I'm using Ice 3.4.1 on Windows XP with Visual Studio 2010. slice2cs doesn't seem to be generating C# classes for my maps. Running slice2cs on the following code produces the output included below. I just installed 3.4.1 (upgrading from 3.2.1), and I uninstalled 3.2.1 in case slice2cs 3.4.1 was somehow loading DLLs from 3.2.1 or something like that. Any ideas what I might be doing wrong?

Hi Andrew,

The mapping for dictionaries has changed since Ice 3.2. Now your dictionary maps to the following type by default:

System.Collections.Generic.Dictionary<string, string>

This means that the Slice compiler doesn't need to generate a class representing the dictionary because it can reuse the .NET Dictionary class.

This page describes the mapping in more detail.

Mark

Oh.

Mark,

Thanks for the link. Next time I'll read up more on the changes before posting.

Andrew

documentation tweak

Incidentally, while reading this:

http://www.zeroc.com/doc/Ice-3.4.1-IceTouch/manual/Csharp.15.7.html

I noticed a couple typos:

"By default, he Slice-to-C# compiler maps the dictionary to the following type:
System.Collections.Generic.Dictionary<Employee>"

I think this should be:

By default, the Slice-to-C# compiler maps the dictionary to the following type:
System.Collections.Generic.Dictionary<int, Employee>

I noticed those too, and actually the mapped type should be

System.Collections.Generic.Dictionary<long, Employee>

Thanks,
Mark
