SystemColors Class
Assembly: System.Drawing (in system.drawing.dll)
Better performance is achieved by using the properties of the SystemPens or SystemBrushes classes rather than creating a new pen or brush based on a value from SystemColors. For example, if you wanted to get a brush for the face color of a 3-D element, use the SystemBrushes.Control property because it gets a brush that already exists, whereas calling the SolidBrush constructor with a parameter value of SystemColors.Control will create a new brush.
The following code example demonstrates the op_Equality operator and the SystemColors class. This example is designed to be used with a Windows Form that contains a button named Button1. Paste the following code into your form and associate the Button1_Click method with the button's Click event.
Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click If (Color.op_Equality(Me.BackColor, SystemColors.ControlDark)) Then Me.BackColor = SystemColors.Control End If End Sub
private void button1_Click(System.Object sender, System.EventArgs e)
{
if (this.get_BackColor().Equals(SystemColors.get_ControlDark())) {
this.set_BackColor(SystemColors.get_Control());
}
} //button1_Click
