Parsing a nested dictionary with arbitrary numerical keys and object array values

Given the json string

var testJson = @"{'entry1': {
                       '49208118': [
                          {
                             'description': 'just a description'
                          },
                          {
                             'description': 'another description' 
                          }
                       ],
                       '29439559': [
                          {
                             'description': 'just a description'
                          },
                          {
                             'description': 'another description' 
                          }
                       ]
                     }
                }";

The array value of the key 49208118 can be retrieved by 

var root = JToken.Parse(testJson);
var descriptions = root.SelectTokens("..49208118[*]").ToList();

according to this answer.

But how can the whole substructure under entry1 be parsed into a dictionary

 Dictionary<string, JArray> descriptions;

mapping the numerical ids to arrays of JObjects?

Since question is how you can parse entry1 to Dictionary<string, JArray> - easiest option is:

JToken root = JToken.Parse(testJson);
Dictionary<string, JArray> descriptions = root["entry1"].ToObject<Dictionary<string, JArray>>();

Json.NET allows mixing of .NET classes (Dictionary) and his own classes (JArray) without problems when parsing.

How about this:

string selector = String.Format("..{0}[*]", yourKey);
var descriptions = root.SelectTokens(selector).ToList();
