Question

我有一个方法，它在类库中有对象返回类型，我正在使用javascript反序列化器并返回对象数据。并创建了此类的DLL并在另一个项目中调用此类。我正在获取该类中的数据，但混淆了如何在标签控件中显示对象类型数据。

这是类库方法：

public class HttpRequestResponse
{
    private WebRequest request;    
         public object Fetchresult()
    {          
        request = WebRequest.Create("URL");               
        request.Method = "GET";
        request.ContentType = "application/json; charset=utf-8";
        WebResponse response = request.GetResponse();                 Console.WriteLine(((HttpWebResponse)response).StatusDescription);
            dataStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(dataStream);
            string responseFromServer = reader.ReadToEnd();
        JavaScriptSerializer js = new JavaScriptSerializer();
        object obj = js.Deserialize<dynamic>(responseFromServer);
        return obj;               

    }
}

这是调用类：

HttpRequestResponse cls = new HttpRequestResponse();
object obj= cls.Fetchresult();
Label3.Text = obj["name"];

我在obj中获得了值，但是如何在标签控件中显示此值。感谢

Answer 1

这是解决方案

dynamic obj = cls.Fetchresult(i);

也许，你可以这样。所以，你总是有一个你想要的类型的对象。

public class HttpRequestResponse
{
    private WebRequest request;
    public T Fetchresult<T>()
    {
        request = WebRequest.Create("URL");
        request.Method = "GET";
        request.ContentType = "application/json; charset=utf-8";
        WebResponse response = request.GetResponse();
        Console.WriteLine(((HttpWebResponse)response).StatusDescription);
        var dataStream = response.GetResponseStream();
        StreamReader reader = new StreamReader(dataStream);
        string responseFromServer = reader.ReadToEnd();
        JavaScriptSerializer js = new JavaScriptSerializer();
        var obj = js.Deserialize<T>(responseFromServer);
        return obj;

    }
}

可以使用它：

List<int> list = HttpRequestResponse.Fetchresult<List<int>>();

或者

ClassName obj = HttpRequestResponse.Fetchresult<ClassName>();
