如何修复错误代码CS1503?

public async void GetWeatherInfo(CityName city)
    {
        var httpClient = new HttpClient();
        var json = JsonConvert.SerializeObject(city);
        var content = new StringContent(json,Encoding.UTF8,"application/json");

        var uri = new Uri(string.Format("http://api.openweathermap.org/data/2.5/weather?q={0}&appid=29d06aa8c8b3a8341ab876b124d7c&units=metric",json));

        var result = await httpClient.Getasync(uri);

        if (result.IsSuccessStatusCode)
        {
            try
            {
                var weatherInfo = JsonConvert.DeserializeObject<WeatherInfo>(**result**);
        }}}

我正在开发一个天气应用程序项目,并且试图从用户那里获取一个字符串城市名称。我将城市名称绑定到url并编写了GetRequest,但是在代码末尾出现“ 结果”错误。它应该反序列化响应,以便我可以更改响应并使用它。错误消息是:无法从'System.Net.Http.HttpResponseMessage'转换为'string'

说明

HttpClient.getAsync()方法返回一个Task<HttpResponseMessage>,其中还包括状态码和有关响应本身的更多信息。

  

返回任务{HttpResponseMessage}

     

代表异步操作的任务对象。

您需要从结果中提取内容。

解决方案

尝试一下

public async void GetWeatherInfo(CityName city)
    {
        var httpClient = new HttpClient();
        var json = JsonConvert.SerializeObject(city);
        var content = new StringContent(json,Encoding.UTF8,"application/json");

        var uri = new Uri(string.Format("http://api.openweathermap.org/data/2.5/weather?q={0}&appid=29d06aa8c8b3a8341ab876b124d7c&units=metric",json));

        var result = await httpClient.GetAsync(uri);

        if (result.IsSuccessStatusCode)
        {
            try
            {
                string content = await result.Content.ReadAsStringAsync();
                var weatherInfo = JsonConvert.DeserializeObject<WeatherInfo>(content);
        }}}
