傳回
這個運算子轉換成的 SizeF 結構。
範例
下列程式代碼範例示範 G和 成員的 Color 、RB、 和 AImplicit 屬性。
此範例的設計目的是要與 Windows Form 搭配使用。 將程式代碼貼到表單中,並從表單Paint的事件處理方法呼叫 ShowPropertiesOfSlateBlue
方法,並e
傳遞為 PaintEventArgs。
void ShowPropertiesOfSlateBlue( PaintEventArgs^ e )
{
Color slateBlue = Color::FromName( "SlateBlue" );
Byte g = slateBlue.G;
Byte b = slateBlue.B;
Byte r = slateBlue.R;
Byte a = slateBlue.A;
array<Object^>^temp0 = {a,r,g,b};
String^ text = String::Format( "Slate Blue has these ARGB values: Alpha:{0}, "
"red:{1}, green: {2}, blue {3}", temp0 );
e->Graphics->DrawString( text, gcnew System::Drawing::Font( this->Font,FontStyle::Italic ), gcnew SolidBrush( slateBlue ), RectangleF(PointF(0.0F,0.0F),this->Size) );
}
private void ShowPropertiesOfSlateBlue(PaintEventArgs e)
{
Color slateBlue = Color.FromName("SlateBlue");
byte g = slateBlue.G;
byte b = slateBlue.B;
byte r = slateBlue.R;
byte a = slateBlue.A;
string text = String.Format("Slate Blue has these ARGB values: Alpha:{0}, " +
"red:{1}, green: {2}, blue {3}", new object[]{a, r, g, b});
e.Graphics.DrawString(text,
new Font(this.Font, FontStyle.Italic),
new SolidBrush(slateBlue),
new RectangleF(new PointF(0.0F, 0.0F), this.Size));
}
