向此窗体添加附属窗体。
public:
void AddOwnedForm(System::Windows::Forms::Form ^ ownedForm);C#
public void AddOwnedForm (System.Windows.Forms.Form ownedForm);C#
public void AddOwnedForm (System.Windows.Forms.Form? ownedForm);member this.AddOwnedForm : System.Windows.Forms.Form -> unitPublic Sub AddOwnedForm (ownedForm As Form)以下示例演示如何使用 AddOwnedForm 该方法将窗体显示为另一个窗体的自有窗体。 显示拥有的窗体后，可以最小化其所有者表单，拥有的表单将最小化。 该示例要求从窗体的另一个事件或方法调用示例中的代码。
private:
void ShowMyOwnedForm()
{
// Create an instance of the form to be owned.
Form^ ownedForm = gcnew Form;
// Set the text of the form to identify it is an owned form.
ownedForm->Text = "Owned Form";
// Add ownedForm to array of owned forms.
this->AddOwnedForm( ownedForm );
// Show the owned form.
ownedForm->Show();
}
C#
private void ShowMyOwnedForm()
{
// Create an instance of the form to be owned.
Form ownedForm = new Form();
// Set the text of the form to identify it is an owned form.
ownedForm.Text = "Owned Form";
// Add ownedForm to array of owned forms.
this.AddOwnedForm(ownedForm);
// Show the owned form.
ownedForm.Show();
}
Private Sub ShowMyOwnedForm()
' Create an instance of the form to be owned.
Dim ownedForm As New Form()
' Set the text of the form to identify it is an owned form.
ownedForm.Text = "Owned Form"
' Add ownedForm to array of owned forms.
Me.AddOwnedForm(ownedForm)
' Show the owned form.
ownedForm.Show()
End Sub
分配给所有者窗体的表单将保留所有，直到 RemoveOwnedForm 调用该方法。 还可以通过将属性设置为 Owner 对其所有者窗体的引用，使另一个窗体拥有该窗体。
当窗体由另一个窗体拥有时，它将与所有者窗体一起关闭或隐藏。 For example, consider a form named Form2 that is owned by a form named Form1. 如果 Form1 已关闭或最小化， Form2 则也会关闭或隐藏。 拥有的表单也永远不会显示在其所有者窗体后面。 可以将拥有的窗体用于窗口，例如查找和替换窗口，选择所有者窗体时不应显示在所有者窗体后面。
备注
如果窗体是多文档界面 (MDI) 父窗体，则此属性返回除当前打开的任何 MDI 子窗体之外显示的所有窗体。 若要获取在 MDI 父窗体中打开的 MDI 子窗体，请使用 MdiChildren 该属性。
