通常情况下，我会做Application.Run（myMainForm）。

不过，我想要做的事情是这样的：

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

无效OnOpenOverviewWin（）
{
MyOverViewForm F =新MyOverViewForm（）;
Application.Run（F）; //我想这样做
Application.NewMainWindow = F; // 或类似的东西
}
 

解决方案

设置的 Application.ShutdownMode 财产 ShutdownMode.OnLastWindowClose

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

无效OnOpenOverviewWin（）
{
  MyOverViewForm F =新MyOverViewForm（）;
  f.Show（）;
}
 

Normally I would do Application.Run(myMainForm).

But I want to do something like this:

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
}

Set the Application.ShutdownMode property to ShutdownMode.OnLastWindowClose

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

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