推荐答案

首先推荐的是不要使用任何复杂的逻辑形式的构造，但在窗体的< STRONG> Load事件（在onload方法或重写）。

First recommendation is do not use any complicated logic in the form constructor, but in the form's Load event(or overrides of the OnLoad method).

设计者采用构造的code显示表单，如果你有错误，你的表格会在VS设计师成为不可。

The designer uses the code of constructor to display the form, and if you have errors your form will be "undisplayable" in the VS designer.

其次，每次你在设计问题时，关闭它并重建窗体的项目。验证错误列表窗口中的错误和警告。固定后，在DESIG模式重新打开表单。

Secondly, every time you have problems in the designer, close it and rebuild your form's project. Verify the errors and warnings in the error list Window. After fixing it, reopen your form in desig mode.
