Return Value
The Color that this method creates.The following code example demonstrates the G, B, R, A, and FromName members of a Color, and the op_Implicit member.
This example is designed to be used with a Windows Form. Paste the code into the form and call the ShowPropertiesOfSlateBlue method from the form's Paint event-handling method, passing e as 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");
ubyte g = slateBlue.get_G();
ubyte b = slateBlue.get_B();
ubyte r = slateBlue.get_R();
ubyte a = slateBlue.get_A();
String text = String.Format(
"Slate Blue has these ARGB values: Alpha:{0}, "
+ "red:{1}, green: {2}, blue {3}",
new Object[] { (UInt16)a, (UInt16)r, (UInt16)g, (UInt16)b });
e.get_Graphics().DrawString(text,
new Font(this.get_Font(), FontStyle.Italic),
new SolidBrush(slateBlue),
new RectangleF(new PointF(0, 0),
Size.op_Implicit(this.get_Size())));
} //ShowPropertiesOfSlateBlue
