推荐答案

您需要使用类System.Net.HttpWebRequest.要创建一个，您需要使用类System.Net.WebRequest的编译时变量及其静态工厂方法Create，因为运行时类型是由URI定义的.您System.Net.HttpWebRequest.Method应该是"GET".

You need to use the class System.Net.HttpWebRequest. To create one, you need to use the compile-time variable of the class System.Net.WebRequest and its static factory method Create, as the run-time type is defined by the URI. You System.Net.HttpWebRequest.Method should be "GET".

假设您使用的是Visual Studio版本，则至少应有一个包含Listbox和Button的Form事件处理代码.然后，您将需要编写更多代码来接收数据，如有必要，对其进行解析，然后填充列表框.我猜您将使用 Web浏览器 [ ^ ]控件可以访问您的互联网数据.

Assuming you have a version of Visual Studio, then you should at least have a Form containing a Listbox and Button with some event handling code. You will then need to write some more code to receive your data, parse it if necessary, and populate your listbox. I would guess you will be using a WebBrowser[^] control to get access to your internet data.
