推荐答案

它不能那样工作：你表示什么是假设的布尔属性点击类按钮（我假设你的意思是System.Windows.Forms.Button）以事件的形式存在，名为点击。事件不像理论代码示例中的字段或属性那样被读取。他们正在订阅，当他们解雇订阅他们的方法（事件处理程序）时。



尝试这个：

- 打开或创建一个带有表单的项目。

- 在设计器中打开表单并在其上放一个按钮。

- 双击按钮。 Visual Studio会自动创建方法存根（如果不重命名按钮，则命名为Button1_Click）并将其添加到该按钮的Click事件的订阅者列表中。只要单击该按钮，就会调用该方法。

- 编写单击按钮进入该方法时应执行的代码。



我强烈建议你找一些书和/或好的在线教程。你显然是一名初学者，在这一点上，你将从一本书或类似的书中学到更快更全面的知识，而不是在论坛上提问。

It doesn't work like that: What you denote as a hypothetical boolean property "clicked" of the class Button (I assume you mean System.Windows.Forms.Button) exists in form of an event named Click. Events aren't being read like a field or a property like in your theoretical code sample. They're being subscribed to and when they "fire" the method(s) that are subscribed to them ("event-handlers") are being called.

Try this:
- Open or create a project with a form.
- Open the form in the designer and place a button onto it.
- Double-click the button. Visual Studio automatically creates a method-stub (named "Button1_Click" if you didn't rename the button) and adds it to the subscriber-list of the Click-event of that button. Whenever the button is clicked that method will be called.
- Write the code that should be executed when the button is clicked into that method.

I strongly recommend you to find some books and/or good online tutorials. You're obviously a beginner and at that point you will learn faster and more thoroughly from a book or similar than asking in forums.
