从wpf中的另一个类访问公共类

问题描述

我正在开发一个 wpf 应用程序.在这个应用程序中，我收到了来自服务器的 JSON 响应并将其反序列化如下:-

I am working on a wpf application. In this application I received JSON response from server and deserialize it as follow :-

StreamReader streamReader = new StreamReader(jsonResponse.GetResponseStream());
                String responseData = streamReader.ReadToEnd();
                var myData = JsonConvert.DeserializeObject<List<RootObject>>(responseData);
                //UserData ud = new UserData();
                foreach (var val in myData)
                {
                    string res = val.response;
                    if (res == "true")
                    {
                        this.Hide();
                        new lobby().Show();

                    }
                }

我的课程如下:-

public class RootObject
{
    public string response { get; set; }
    public string user_id { get; set; }
    public string username { get; set; }
    public string current_balance { get; set; }
    public string message { get; set; }
    public string oauth_token { get; set; }
    public List<string> lastFiveSpinNumbers { get; set; }

}

当我执行此代码时一切正常，并且在检查响应 lobby.xaml 打开后.现在我需要访问 lobby.xaml.cs 中 RootObject 类的值.所以我创建了这个类的一个实例如下:-

When I execute this code everything is ok and after checking response lobby.xaml open. Now I need to access values of RootObject class in lobby.xaml.cs. So I created an instance of this class as follow:-

RootObject cd = new RootObject();
UserNameTextBlock.Text = cd.response;

但 cd.response 始终为空.可能是什么原因?

but cd.response is always null. What may be the reason?

推荐答案

您正在创建 RootObject 的新实例，默认情况下 response 属性为 null.

You are creating a new instance of RootObject and by default the response property is null.

你可以给你的 lobby 类一个构造函数，它接受一个 RootObject:

You can give your lobby class a constructor that takes in a RootObject:

public class lobby
{
   public lobby(RootObject rootObject)
   {
       UserNameTextBlock.Text = rootObject.response;
   }
}

然后在您的 foreach 中，您可以执行以下操作:

Then in your foreach you could do:

if (res == "true")
{
   this.Hide();
   new lobby(val).Show(); // Pass the root object to the Lobby constructor
}

注意:您可能希望将 lobby 重命名为 Lobby 作为您的类名，这符合更好的 C# 命名约定.

Note: You may wish to rename lobby to Lobby for your class name, this adheres to better C# naming conventions.
