Color.FromName Method (String)
Creates a Color structure from the specified name of a predefined color.
Assembly: System.Drawing (in System.Drawing.dll)
Parameters
- name
-
Type:
System.String
A string that is the name of a predefined color. Valid names are the same as the names of the elements of the KnownColor enumeration.
A predefined color is also called a known color and is represented by an element of the KnownColor enumeration. If the name parameter is not the valid name of a predefined color, the FromName method creates a Color structure that has an ARGB value of 0 (that is, all ARGB components are 0).
The following code example demonstrates the A, R, G, B, and FromName members of a Color, and the Implicit(Size to SizeF) 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.
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)); }
