Ice for .NET supports two mappings for dictionaries. By default, a dictionary maps to System.Collections.Generic.Dictionary<T>. You can use a metadata directive to map a dictionary to System.Collections.Generic.SortedDictionary instead.

Default Mapping for Dictionaries in C#

Here is the definition of our EmployeeMap once more:

dictionary<long, Employee> EmployeeMap;

By default, the Slice-to-C# compiler maps the dictionary to the following type:

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

Custom Mapping for Dictionaries in C#

You can use the "clr:generic:SortedDictionary" metadata directive to change the default mapping to use a sorted dictionary instead:

["clr:generic:SortedDictionary"]
dictionary<long, Employee> EmployeeMap;

With this definition, the type of the dictionary becomes:

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