问题描述
嗨:)我正在为游戏制作一个简单的alt客户端，我差不多完成了，我所做的大部分工作都在我的能力之内。但是我需要添加商品价格查询。如何将其链接到GUI，我希望价格出现在文本框中。非常感谢提前。
Hi :) I'm making a simple alt client for a game, I'm almost done and most of what I've done has been within my ability. However I need to add an item price lookup. How can I link this to a GUI, I want the price to appear in a textbox. Thanks so much in advance.

推荐答案
你没有 - 你的类不是从Control派生的，所以它不能直接显示任何东西。我甚至不高兴使用MessageBox，我自己...
它与名称空间无关......
我们的想法是你的UI使用非UI类来组合数据以供显示;该类甚至不应该尝试显示数据，因为它应该不知道应该在哪个环境中找到它自己：网站可以使用与WinForms应用程序相同的类，作为WPF应用程序，作为Xamarin iOS应用程序而不更改类。
所以不要看这里，看看你的UI使用你的类来处理你的UI显示的数据。
You don't - your class is not derived from a Control, so it can't display anything directly. I wouldn't even be happy about it using MessageBox, myself...
And it has nothing to do withnamespaceseither...
The idea is that your UI uses your non-UI classes to assemble data for it to display; the class should not even try to display data because it should have no idea what environment it should find it self in: a website could use the same classes as a WinForms app, as a WPF app, as a Xamarin iOS app without your classes changing.
So don't look here, look at your UI to use your classes to process the data for your UI to display for itself.
