Color.Equality(Color, Color) Color.Equality(Color, Color) Color.Equality(Color, Color) Color.Equality(Color, Color) Operator

Definition

Tests whether two specified Color structures are equivalent.

public:
 static bool operator ==(System::Drawing::Color left, System::Drawing::Color right);
public static bool operator == (System.Drawing.Color left, System.Drawing.Color right);
static member ( = ) : System.Drawing.Color * System.Drawing.Color -> bool
Public Shared Operator == (left As Color, right As Color) As Boolean

Parameters

left
Color Color Color Color

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

right
Color Color Color Color

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

Returns

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

Examples

The following code example demonstrates the 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.

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

Remarks

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.
