Windows窗体：在运行时更改应用程序主窗口

Question

通常我会做Application.Run（myMainForm）。

但我想做这样的事情：

MyForm1 f = new MyForm1();
f.Close+=OnOpenOverviewWin();
Application.Run(f);

void OnOpenOverviewWin()
{
MyOverViewForm f = new MyOverViewForm ();
Application.Run(f); // i want to do this
Application.NewMainWindow = f; // or something like that
}

Answer 1

将Application.ShutdownMode属性设置为ShutdownMode.OnLastWindowClose

MyForm1 f = new MyForm1();
f.Close += OnOpenOverviewWin();
Application.ShutdownMode = ShutdownMode.OnLastWindowClose;
Application.Run(f);

void OnOpenOverviewWin()
{
  MyOverViewForm f = new MyOverViewForm ();
  f.Show();
}
