示例

下面的代码示例演示如何使用 ToBitmap 该方法。 此示例旨在与 Windows 窗体一起使用。 创建窗体并将以下代码粘贴到其中。 IconToBitmap在窗体的Paint事件处理程序中调用该方法，并e传递为 PaintEventArgs.

private:
   void IconToBitmap( PaintEventArgs^ e )
   {
      // Construct an Icon.
      System::Drawing::Icon^ icon1 = gcnew System::Drawing::Icon( SystemIcons::Exclamation,40,40 );

      // Call ToBitmap to convert it.
      Bitmap^ bmp = icon1->ToBitmap();

      // Draw the bitmap.
      e->Graphics->DrawImage( bmp, Point(30,30) );
   }

private void IconToBitmap(PaintEventArgs e)
{
    // Construct an Icon.
    Icon icon1 = new Icon(SystemIcons.Exclamation, 40, 40);

    // Call ToBitmap to convert it.
    Bitmap bmp = icon1.ToBitmap();

    // Draw the bitmap.
    e.Graphics.DrawImage(bmp, new Point(30, 30));
}

Private Sub IconToBitmap(ByVal e As PaintEventArgs)

    ' Construct an Icon.
    Dim icon1 As New Icon(SystemIcons.Exclamation, 40, 40)

    ' Call ToBitmap to convert it.
    Dim bmp As Bitmap = icon1.ToBitmap()

    ' Draw the bitmap.
    e.Graphics.DrawImage(bmp, New Point(30, 30))
End Sub

注解

可以从文件、流或嵌入资源构造 Icon 对象。 有关构造函数的列表，请参阅 Icon。 还可以使用Icon该方法将位ToBitmap图转换为位图。

图标资源可以包含多个图标图像。 一个图标文件可能包含多个大小和颜色深度的图像。 应用程序中使用的映像取决于操作系统和设置。 以下列表详细介绍了图标的典型大小：

• 16 像素 x 16 像素

• 32 像素 x 32 像素

• 48 像素 x 48 像素
