Control.Size 屬性

定義

取得或設定控制項的高度和寬度。Gets or sets the height and width of the control.

public:
 property System::Drawing::Size Size { System::Drawing::Size get(); void set(System::Drawing::Size value); };
public System.Drawing.Size Size { get; set; }
member this.Size : System.Drawing.Size with get, set
Public Property Size As Size

屬性值

表示控制項高度和寬度的 Size (單位為像素)。The Size that represents the height and width of the control in pixels.

範例

下列程式碼範例會將 Button 新增至表單,並設定其一些通用屬性。The following code example adds a Button to a form and sets some of its common properties. 這個範例會將按鈕錨定表單右下角,讓它在調整大小表單時保持相對位置。The example anchors the button to the bottom-right corner of the form so it keeps its relative position as the form is resized. 接下來,它會設定 BackgroundImage,並將按鈕大小調整為與 Image 相同的大小。Next it sets the BackgroundImage and resizes the button to the same size as the Image. 然後,此範例會將 TabStop 設定為 true,並設定 TabIndex 屬性。The example then sets the TabStop to true and sets the TabIndex property. 最後,它會加入事件處理常式來處理按鈕的 Click 事件。Lastly, it adds an event handler to handle the Click event of the button. 這個範例需要您的 ImageList,名為 imageList1This example requires that you have an ImageList named imageList1.

   // Add a button to a form and set some of its common properties.
private:
   void AddMyButton()
   {
      // Create a button and add it to the form.
      Button^ button1 = gcnew Button;

      // Anchor the button to the bottom right corner of the form
      button1->Anchor = static_cast<AnchorStyles>(AnchorStyles::Bottom | AnchorStyles::Right);

      // Assign a background image.
      button1->BackgroundImage = imageList1->Images[ 0 ];

      // Specify the layout style of the background image. Tile is the default.
      button1->BackgroundImageLayout = ImageLayout::Center;

      // Make the button the same size as the image.
      button1->Size = button1->BackgroundImage->Size;

      // Set the button's TabIndex and TabStop properties.
      button1->TabIndex = 1;
      button1->TabStop = true;

      // Add a delegate to handle the Click event.
      button1->Click += gcnew System::EventHandler( this, &Form1::button1_Click );

      // Add the button to the form.
      this->Controls->Add( button1 );
   }
// Add a button to a form and set some of its common properties.
private void AddMyButton()
{
   // Create a button and add it to the form.
   Button button1 = new Button();

   // Anchor the button to the bottom right corner of the form
   button1.Anchor = (AnchorStyles.Bottom | AnchorStyles.Right);

   // Assign a background image.
   button1.BackgroundImage = imageList1.Images[0];

   // Specify the layout style of the background image. Tile is the default.
   button1.BackgroundImageLayout = ImageLayout.Center;
   
   // Make the button the same size as the image.
   button1.Size = button1.BackgroundImage.Size;

   // Set the button's TabIndex and TabStop properties.
   button1.TabIndex = 1;
   button1.TabStop = true;

   // Add a delegate to handle the Click event.
   button1.Click += new System.EventHandler(this.button1_Click);

   // Add the button to the form.
   this.Controls.Add(button1);
}
' Add a button to a form and set some of its common properties.
Private Sub AddMyButton()
   ' Create a button and add it to the form.
   Dim button1 As New Button()
   
   ' Anchor the button to the bottom right corner of the form
   button1.Anchor = AnchorStyles.Bottom Or AnchorStyles.Right
   
   ' Assign a background image.
   button1.BackgroundImage = imageList1.Images(0)

   ' Specify the layout style of the background image. Tile is the default.
   button1.BackgroundImageLayout = ImageLayout.Center
   
   ' Make the button the same size as the image.
   button1.Size = button1.BackgroundImage.Size
   
   ' Set the button's TabIndex and TabStop properties.
   button1.TabIndex = 1
   button1.TabStop = True

   ' Add a delegate to handle the Click event.
   AddHandler button1.Click, AddressOf Me.button1_Click
   
   ' Add the button to the form.
   Me.Controls.Add(button1)
End Sub

備註

因為 Size 類別是實值型別(Visual Basic 中的 Structure,在 Visual C#中則為 struct),它是以傳值方式傳回,這表示存取屬性會傳回控制項大小的複本。Because the Size class is a value type (Structure in Visual Basic, struct in Visual C#), it is returned by value, meaning accessing the property returns a copy of the size of the control. 因此,調整從這個屬性傳回之 SizeWidthHeight 屬性,並不會影響控制項的 WidthHeightSo, adjusting the Width or Height properties of the Size returned from this property will not affect the Width or Height of the control. 若要調整控制項的 WidthHeight,您必須設定控制項的 WidthHeight 屬性,或使用新的 Size 設定 Size 屬性。To adjust the Width or Height of the control, you must set the control's Width or Height property, or set the Size property with a new Size.

注意

若要維持較佳的效能,請不要在其函式中設定控制項的 SizeTo maintain better performance, do not set the Size of a control in its constructor. 慣用的方法是覆寫 DefaultSize 屬性。The preferred method is to override the DefaultSize property.

注意

在 Windows Server 2003 系統上,Form 的大小受限於監視的最大圖元寬度和高度。On Windows Server 2003 systems, the size of a Form is restricted by the maximum pixel width and height of the monitor.
