Windows 窗体：在运行时更改应用程序主窗口

Question

通常我会执行 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 < a href="http://msdn.microsoft.com/en-us/library/system.windows.shutdownmode.aspx" rel="nofollow noreferrer">ShutdownMode.OnLastWindowClose

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

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