C# Generics: 'x' is a 'type' but used like a 'variable'

For some reason, this code won't compile:

JsonSerializer serializer = new JsonSerializer();
_sectionStories = 开发者_如何学Pythonserializer.Deserialize < IDictionary<int, ObservableCollection<Story>>(new JTokenReader(contents));

The error:

Error 91 'System.Collections.Generic.IDictionary>' is a 'type' but is used like a 'variable'

What am I doing wrong here? I feel like I'm missing something basic.

Looks like a typo. I see three < but only two >.

You are missing a >.

For illustrative purposes, I have matched up the <s and >s below:

_sectionStories = serializer.Deserialize<
                     IDictionary<
                        int,
                        ObservableCollection<Story>
                     >
                  >(new JTokenReader(contents)));

i think the good synthaxe is :

JsonSerializer serializer = new JsonSerializer();
        _sectionStories = serializer.Deserialize < IDictionary<int, ObservableCollection<Story>>>(new JTokenReader(contents));
