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

示例

下面的代码示例将 Button 添加到窗体中,并设置其一些公共属性。The following code example adds a Button to a form and sets some of its common properties. 该示例将按钮锚定在窗体右下角,以便在调整窗体大小时保持其相对位置。The example anchors the button to the bottom-right corner of the form so it keeps its relative position as the form is resized. 接下来,它将 BackgroundImage 并将按钮的大小调整为与 Image 相同的大小。Next it sets the BackgroundImage and resizes the button to the same size as the Image. 然后,该示例将 TabStop 设置为 true 并设置 TabIndex 属性。The example then sets the TabStop to true and sets the TabIndex property. 最后,添加一个事件处理程序来处理按钮的 Click 事件。Lastly, it adds an event handler to handle the Click event of the button. 此示例要求你有一个名为 imageList1ImageListThis 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

   ' Set the button's TabIndex and TabStop properties.
   button1.TabIndex = 1
   button1.TabStop = True

   ' Add a delegate to handle the Click event.

   ' Add the button to the form.
   Me.Controls.Add(button1)
End Sub

注解

由于 Size 类是值类型(在 Visual Basic 中Structurestruct 在视觉对象C#中),因此它按值返回,这意味着访问属性将返回控件大小的副本。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,调整从此属性返回的 SizeWidthHeight 属性将不会影响控件的 WidthHeightSo, adjusting the Width or Height properties of the Size returned from this property will not affect the Width or Height of the control. 若要调整控件的 WidthHeight,必须设置控件的 WidthHeight 属性,或使用新的 Size 设置 Size属性。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.

备注

若要保持更好的性能,请不要在其构造函数中设置控件的 SizeTo maintain better performance, do not set the Size of a control in its constructor. 首选方法是重写 DefaultSize 属性。The preferred method is to override the DefaultSize property.

备注

在 Windows Server 2003 系统上,Form 的大小受监视器的最大像素宽度和高度的限制。On Windows Server 2003 systems, the size of a Form is restricted by the maximum pixel width and height of the monitor.
