I am trying to convert a http response message into an IEnumerable, but I get the error:

JsonException: The JSON value could not be converted to System.Collections.Generic.IEnumerable 1[MyProject.Models.MyClass]. Path: $ | LineNumber: 0 | BytePositionInLine: 1.

Here is my code:

[HttpGet]
        public async Task<IEnumerable<MyClass>> GetAsync()
        {
            var httpRequestMessage = new HttpRequestMessage(
               HttpMethod.Get,
               "https://xxx/api/123")
            {
                Headers =
                {
                    { HeaderNames.Authorization, "password" },
                }
            };

            var httpClient = _httpClientFactory.CreateClient();
            var httpResponseMessage = await httpClient.SendAsync(httpRequestMessage);

            if (httpResponseMessage.IsSuccessStatusCode)
            {
                using var contentStream =
                    await httpResponseMessage.Content.ReadAsStreamAsync();

                Ipads = await JsonSerializer.DeserializeAsync
                    <IEnumerable<MyClass>>(contentStream); // HERE IS WHERE THE ERROR HITS
            }

            return MyClasses;
        }

Here is the same GET but in Postman working:

Thanks beforehand! Best regards Max

CodePudding user response：

You need to await the content from the HttpResponseMessage as string.

var responseContent = await httpResponseMessage.Content.ReadAsStringAsync();
var model = JsonConvert.DeserializeObject<MyClass>(responseContent);
