示例
下面的代码示例演示 G B 了和成员的、、 R 和 A 属性 Color Implicit 。The following code example demonstrates the G, B, R, and A properties of a Color and the Implicit member.
此示例旨在与 Windows 窗体一起使用。This example is designed to be used with a Windows Form. 将代码粘贴到窗体中,并 ShowPropertiesOfSlateBlue
从窗体的事件处理方法中调用方法,并将 Paint e
作为传递 PaintEventArgs 。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");
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));
}
