推荐答案

您无需刷新或重新加载表单。如果您关闭了表单，则无法再次打开它，因为它会被丢弃。而是调用 Form1.Hide（）然后调用 Form1.Show（）。



这与 Form1_Load 完全无关;如果你不想拥有它，你甚至不需要这种方法;它必须是事件的处理程序 Form.Load ，但是，正式地说，你的帖子中没有任何内容告诉它;你知道只有当某个事件实例上的运算符'+ ='被显示时，某些方法才被用作处理程序。



永远不要使用自动生成的名称，如 Form1中;它们不是为了永久使用而违反（良好）Microsoft命名约定;更糟糕的是，它们没有语义;你应该以语义合理的方式重命名所有内容： MainForm ， SplashScreenForm 等等。

You don't need to "refresh or reload" a form. If you closed a form, you cannot open it again, because it becomes disposed. Instead call Form1.Hide() and later call Form1.Show().

This is totally unrelated to Form1_Load; you don't even need this method, if you don't want to have it; it must be the handler of the event Form.Load, but, formally speaking, nothing in your post tells as about it; you know that some method is used as a handler only if the operator '+=' on some event instance is shown.

And never use auto-generated names like Form1; they are not intended for permanent use and violate (good) Microsoft naming conventions; worse, they carry no semantics; you should rename everything in semantically sensible way: MainForm, SplashScreenForm and the like.
