Deserialize json array of dictionaries in c#

Question

I have an array of dictionaries that I\'ve created in javascript. After serializing to json I get the following string :

\"[{\\\"key\\\":\\\"60236\\\",\\\"va

There are several ways that you can extract your key/value pairs to construct a dictionary:

var dict = "[{\"key\":\"60236\",\"value\":\"1\"},  
             {\"key\":\"60235\",\"value\":\"gdsfgdfsg\"},
             {\"key\":\"60237\",\"value\":\"1\"}]";

Use List>

var dictionary = JsonConvert.DeserializeObject>>(dict)
                                 .ToDictionary(x => x.Key, y => y.Value);

Use a custom object that represents your pairs and then create a dictionary from your collection.

var output = JsonConvert.DeserializeObject>(dict);
var dictionary = output.ToDictionary(x => x.Key, y => y.Value);

public class Temp
{
    public int Key { get; set; }
    public string Value { get; set; }
}

Finally, if you're uncomfortable with using a custom "throwaway" object just for deserialization, you can take a tiny performance hit and use dynamic instead.

var dictionary = JsonConvert.DeserializeObject>(dict)
                                 .ToDictionary (x => (int)x.key, y => (string)y.value);
