Passing json data to a WebApi with special characters results to null

Question

I have a json string that is being passed to a webapi, now the problem is, when I try adding special characters, the recieving object becomes null.

Here\'s I do it.

Answer 1

Please see the code below. Note: I did not use JsonConvert.SerializeObject and used HttpClient instead of WebClient

    public static HttpRequestMessage CreateRequest(string requestUrl, HttpMethod method, String obj)
    {
        var request = new HttpRequestMessage
        {
            RequestUri = new Uri(requestUrl),
            Method = method,
            Content = new StringContent(obj, Encoding.UTF8, "application/json")
        };

     return request;
    }
    public static void DoAPI()
    {
        var client = new HttpClient();
        var obj = "{\"Firstname\":\"kyv®\",\"Lastname\":\"sab®\"}";
        var httpRequest = CreateRequest("mywebapiURL", HttpMethod.Post, obj);
        var response = client.SendAsync(httpRequest).Result;
        Console.WriteLine(response.Content.ReadAsStringAsync().Result);
    }

Answer 2

You need to set the Encoding of the WebClient

client.Encoding = Encoding.UTF8;
