Unable to cast object of type 'RestSharp.JsonArray'

[Jonathan Channon]

This is probably obviously but I can't see the problem.

Below is my code and JSON. Can anyone point me in the right direction?

The response from RestSharp is throwing the error:

    Unable to cast object of type 'RestSharp.JsonArray' to type 'System.Collections.Generic.IDictionary`2[System.String,System.Object]'.

Is it because the Tags on the first JSON data is null?

**Code**

    var client = new RestClient(this.Context.Request.Url.ToString());

    

    var request = new RestRequest("SugarTown/Posts", Method.GET);

    

    request.AddHeader("Accept", "application/json");

    

    var response2 = client.Execute<List<Post>>(request);

**JSON**

    [

        {

            "Id": "posts/1",

            "Title": "testes jkl",

            "DateCreated": "/Date(-59011459200000)/",

            "Body": "<p><strong>sccsdc</strong></p>",

            "Tags": null

        },

        {

            "Id": "posts/33",

            "Title": "yeah baby",

            "DateCreated": "/Date(-59011459200000)/",

            "Body": "<p><span style=\"text-decoration: underline;\"><strong>jkljk jklj lkjkl kj&nbsp;</strong></span></p>\r\n<ol>\r\n<li><strong><span style=\"text-decoration: underline;\">,lk</span></strong></li>\r\n<li><strong><span style=\"text-decoration: underline;\">98</span></strong></li>\r\n</ol>",

            "Tags": [

                "asd",

                "qwe",

                "fgh",

                "jh"

            ]

        }

    ]

**Model**

    public class Post

    {

        public string Id { get; set; }

        public string Title { get; set; }

        public DateTime DateCreated { get; set; }

        public string Body { get; set; }

        public Collection<string> Tags { get; set; }

    }

Its probably how you defined Collection. It'll probably work if you make it a List<string>.

I'll give it a try but I've read its not good to expose List<T>

[Jonathan Channon]

To confirm List<T> resolves the issue
