窗体对象，计算机程序术语，是一种文档，可以用来收集信息，包括两部分。
控件是包含在窗体对象内的对象。
Controls are objects that are contained within form objects.
您还可以从工具箱将这些对象拖放到窗体以创建应用程序。
You can also drag and drop these objects from the toolbar onto forms to create applications.
当作了这些修改以后，我使用调试器证实：当执行相同的测试案例时，与被删除的窗体相关联的对象计数减小。
After I made these code changes, I used the debugger to verify that the object count associated with the deleted form decreased when the same test case was executed.
