範例

下列範例示範如何使用 MdiChildren 屬性逐一 Button 查看 MDI 子表單清單，並將控制項新增至每個表單。

private:
   void AddButtonsToMyChildren()
   {
      // If there are child forms in the parent form, add Button controls to them.
      for ( int x = 0; x < this->MdiChildren->Length; x++ )
      {
         // Create a temporary Button control to add to the child form.
         Button^ tempButton = gcnew Button;

         // Set the location and text of the Button control.
         tempButton->Location = Point(10,10);
         tempButton->Text = "OK";

         // Create a temporary instance of a child form (Form 2 in this case).
         Form^ tempChild = dynamic_cast<Form^>(this->MdiChildren[ x ]);

         // Add the Button control to the control collection of the form.
         tempChild->Controls->Add( tempButton );
      }
   }

private void AddButtonsToMyChildren()
{
   // If there are child forms in the parent form, add Button controls to them.
   for (int x =0; x < this.MdiChildren.Length;x++)
   {
      // Create a temporary Button control to add to the child form.
      Button tempButton = new Button();
      // Set the location and text of the Button control.
      tempButton.Location = new Point(10,10);
      tempButton.Text = "OK";
      // Create a temporary instance of a child form (Form 2 in this case).
      Form tempChild = (Form)this.MdiChildren[x];
      // Add the Button control to the control collection of the form.
      tempChild.Controls.Add(tempButton);
   }
}

Private Sub AddButtonsToMyChildren()
    ' If there are child forms in the parent form, add Button controls to them.
    Dim x As Integer
    For x = 0 To (Me.MdiChildren.Length) - 1
        ' Create a temporary Button control to add to the child form.
        Dim tempButton As New Button()
        ' Set the location and text of the Button control.
        tempButton.Location = New Point(10, 10)
        tempButton.Text = "OK"
        ' Create a temporary instance of a child form (Form 2 in this case).
        Dim tempChild As Form = CType(Me.MdiChildren(x), Form)
        ' Add the Button control to the control collection of the form.
        tempChild.Controls.Add(tempButton)
    Next x
End Sub

備註

此屬性可讓您取得目前在 MDI 父表單中開啟之所有 MDI 子表單的參考。 若要建立 MDI 子表單，請將 MDI 父表單指派 Form 給 MdiParent 子表單的 屬性。

您可以使用此屬性來迴圈查看所有 MDI 子表單，以執行作業，例如在 MDI 父表單關閉時將資料儲存至資料庫，或根據應用程式中執行的動作更新子表單上的欄位。
