Color.Inequality Operator (Color, Color)

 

Tests whether two specified Color structures are different.

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

public static bool operator !=(
	Color left,
	Color right
)

Parameters

left
Type: System.Drawing.Color

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

right
Type: System.Drawing.Color

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

Return Value

Type: System.Boolean

true if the two Color structures are different; 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, use the ToArgb method.

The following code example demonstrates the Inequality operator and the SystemColors class. This example is designed to be used with a Windows Form that contains a button named Button2. Paste the following code into your form and associate the Button2_Click method with the button's Click event.

private void Button2_Click(System.Object sender, System.EventArgs e)
{

    if (this.BackColor != SystemColors.ControlDark)
    {
        this.BackColor = SystemColors.ControlDark;
    }
    if (!(this.Font.Bold))
    {
        this.Font = new Font(this.Font, FontStyle.Bold);
    }
}
