示例

下面的代码示例向窗体添加一个 Button 值，并设置其一些常见属性。 该示例将按钮定位到窗体的右下角，以便在调整窗体大小时保持其相对位置。 接下来， BackgroundImage 它将按钮的大小设置为与 相同的大小并重设其大小 Image。 然后，该示例设置该 TabStop 属性 true 并设置该 TabIndex 属性。 最后，它会添加事件处理程序来处理 Click 按钮的事件。 此示例要求你有一个命名imageList1项ImageList。

   // 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);
}

注解

Size由于类是值类型（Structure在 Visual Basic 中，struct在 Visual 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。 因此，调整Width从此属性返回的Size或Height属性不会影响Width控件或Height控件。 若要调整Width控件或Height控件，必须设置控件Width或Height属性，或者使用新Size设置属性Size。

注释

若要保持更好的性能，请不要在其构造函数中设置 Size 控件。 首选方法是重写 DefaultSize 属性。

注释

在 Windows Server 2003 系统上，大小 Form 受监视器的最大像素宽度和高度的限制。
