删除任务/异步代码后，我收到以下异常：

以前状态的代码没有问题：

public async Task<HttpResponseMessage> GetAccount(string query)
        {

            var response = Client.Instance.GetAsync(Client.Instance.BaseAddress + query);
            var responseType = response.Result.StatusCode;
            if (responseType == HttpStatusCode.NotFound)
            {
                return new HttpResponseMessage
                {
                    StatusCode = responseType
                };
            }
            return await response;
        }

然后我将其更新为非异步：

    public HttpResponseMessage GetAccount(string query, HttpRequestHeaders headers)
    {
        var requestUri = new Uri(Client.Instance.BaseAddress + query);
        var request = new HttpRequestMessage
        {
            RequestUri = requestUri
        };

        foreach (var header in headers)
        {
            request.Headers.Add(header.Key, header.Value);
        }

        var response = Client.Instance.SendAsync(request).Result;
        return response;
    }

导致此异常的原因是什么？它似乎与async / async有关？

控制器定义如下：

    [HttpGet]
    [Route("accounts({id:guid})")]
    [Route("accounts")]
    public Task<HttpResponseMessage> GetAccount()
    {
        var query = Request.RequestUri.AbsolutePath.Split('/').Last() + Request.RequestUri.Query;
        var response = _accountService.GetAccount(query, Request.Headers);
        return response;
    }
