CS1503 C＃参数1：无法转换为System.IO.Stream＆＃39; to＆＃39; char []＆＃39;

Question

我是C的新手，并且不理解上面标题中的错误，我的代码如下，但错误显示在第7行，（结果）;

public async static Task<RootObject> GetSensor(bool on)
    {
        var http = new HttpClient();
        var response = await http.GetAsync("http://192.168.0.71/api/apikey/sensors");
        var result = await response.Content.ReadAsStreamAsync();
        var serializer = new DataContractJsonSerializer(typeof(RootObject));

        var ms = new MemoryStream(Encoding.UTF8.GetBytes(result));//result is where the error is generated
        var data = (RootObject)serializer.ReadObject(ms);
        return data;
    }

Answer 1

尝试直接

var data = (RootObject)serializer.ReadObject(result);

没有var ms = new MemoryStream(行。 ReadObject接受Stream作为输入，result是Stream。
