示例

下面的代码示例添加Button向窗体,并设置它的一些常见属性。The following code example adds a Button to a form and sets some of its common properties. 示例定位到窗体右下角的按钮,以便在调整窗体大小时,它使其相对位置。The example anchors the button to the bottom-right corner of the form so it keeps its relative position as the form is resized. 接下来设置BackgroundImage调整大小的按钮为具有相同的大小和ImageNext it sets the BackgroundImage and resizes the button to the same size as the Image. 该示例然后设置TabStoptrue,并设置TabIndex属性。The example then sets the TabStop to true and sets the TabIndex property. 最后,它将添加一个事件处理程序以处理Click按钮的事件。Lastly, it adds an event handler to handle the Click event of the button. 此示例要求具有ImageList名为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.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.

End Sub

注解

因为Size类是值类型 (Structure在 Visual Basic 中structVisual C# 中),它返回的值,这意味着访问的属性返回的控件大小的副本。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WidthHeight的属性Size返回此属性将不会影响WidthHeight的控件。So, 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WidthHeight控件,必须设置控件的WidthHeight属性或一组Size具有一个新属性SizeTo 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

若要维护更好的性能,不设置Size的其构造函数中的控件。To maintain better performance, do not set the Size of a control in its constructor. 首选的方法是重写DefaultSize属性。The preferred method is to override the DefaultSize property.

备注

在 Windows Server 2003 系统的大小Form受到限制,最大像素宽度和高度的监视器。On Windows Server 2003 systems, the size of a Form is restricted by the maximum pixel width and height of the monitor.
