HttpResponseMessage.Content.ReadAsStringAsync don't deserialize JSON when it come from CreateErrorResponse

c#, json

Solution

I found that there were extra '\' and '"' in the returned JSON. So before I serialize back to an object, I needed to remove the extra chars.

e.g.

string jsonString = httpResponseMessage.Content.ReadAsStringAsync()
                                               .Result
                                               .Replace("\\", "")
                                               .Trim(new char[1] { '"' });

List<VwAisItemMaster> vwAisItemMasterList = JsonConvert.DeserializeObject<List<VwAisItemMaster>>(jsonString);

Problem

if i return from my selfhosted webapi ``` Request.CreateResponse(HttpStatusCode.OK, "YAY"); ``` everything is fine.. so i can read it like that: ``` var responseStr = await Client.Content.ReadAsAsync<string>(); and then make something like "MessageBox.Show(responseStr); ``` if i return ``` Request.CreateErrorResponse(HttpStatusCode.NotFound, "something went wrong!"); ``` and i read it out the same way or even with(doesn't matter how): ``` Client.Content.ReadAsStringAsync(); ``` the string is not deserialized and i get an error when trying to parse / read as string. if i read it as object .. it's fine.. but i can't perform object.ToString(); i get errors.. why? and how to fix it?
