You are looking for an ownedwindow. It is always on top of the owner and it gets minimized along with the owner. Good examples of owned windows are the various helper windows inside Visual Studio. You can undock them but they'll always stay on top of the VS main window.
您正在寻找拥有的窗户。它始终位于所有者之上，并且与所有者一起最小化。自有窗口的好例子是 Visual Studio 中的各种帮助窗口。您可以取消停靠它们，但它们将始终停留在 VS 主窗口的顶部。
You create an owned window by displaying it with the Show(owner) overload. Or by explicitly assigning its Owner property.
您可以通过使用 Show(owner) 重载来显示它来创建一个拥有的窗口。或者通过显式分配其 Owner 属性。

Set the top level and then set the owner, example below.
设置顶层，然后设置所有者，示例如下。
public Form1()
{
InitializeComponent();
Form2 f2 = new Form2();
//top level not really needed
f2.TopLevel = true;
f2.Show(this);
}
