op_Equality Method

Color.op_Equality Method

Tests whether two specified Color structures are equivalent.

Namespace: System.Drawing
Assembly: System.Drawing (in system.drawing.dll)

public static bool operator == (
	Color left,
	Color right
)
Not applicable.

Parameters

left

The Color that is to the left of the equality operator.

right

The Color that is to the right of the equality operator.

Return Value

true if the two Color structures are equal; otherwise, false.

This method compares more than the ARGB values of the Color structures. It also does a comparison of some state flags. If you want to compare just the ARGB values of two Color structures, compare them using the ToArgb method.

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 void Button1_Click(System.Object sender, System.EventArgs e)
{

    if (this.BackColor == SystemColors.ControlDark)
    {
        this.BackColor = SystemColors.Control;
    }
}

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
