Control.Size 属性

项目
08/17/2007

获取或设置控件的高度和宽度。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
<LocalizableAttribute(True)> _
Public Property Size As Size
用法
Dim instance As Control
Dim value As Size

value = instance.Size

instance.Size = value

[LocalizableAttribute(true)] 
public Size Size { get; set; }

[LocalizableAttribute(true)] 
public:
property Size Size {
    Size get ();
    void set (Size value);
}

/** @property */
public Size get_Size ()

/** @property */
public void set_Size (Size value)

public function get Size () : Size

public function set Size (value : Size)

属性值

Size，表示控件的高度和宽度（以像素为单位）。

备注

由于 Size 类是值类型（在 Visual Basic 中是 Structure，在 Visual C# 中是 struct），它按传值方式返回，意味着访问该属性将返回控件的大小的副本。因此，调整从该属性返回的 Size 的 Width 或 Height 属性将不影响控件的 Width 或 Height。若要调整控件的 Width 或 Height，必须设置控件的 Width 或 Height 属性，或用新的 Size 设置 Size 属性。

提示

若要保持性能更佳，请不要在控件的构造函数中设置控件的 Size。首选方法是重写 DefaultSize 属性。

示例

下面的代码示例将 Button 添加到窗体并设置该控件的一些通用属性。示例将该按钮定位在窗体的右下角，因此调整窗体大小时其相对位置不变。接着，它设置 BackgroundImage 并将该按钮的大小调整为与 Image 同样的大小。然后，该示例将 TabStop 设置为 true，并设置 TabIndex 属性。最后，它添加一个事件处理程序以处理按钮的 Click 事件。此示例要求您有一个名为 imageList1 的 ImageList。

' 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
