Color.Inequality Operator (System.Drawing)

.NET Framework Class Library

Color..::.Inequality Operator

Tests whether two specified Color structures are different.

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

Public Shared Operator <> ( _
	left As Color, _
	right As Color _
) As Boolean

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

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

static let inline (<>)
        left:Color * 
        right:Color  : bool

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.

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, use the ToArgb method.

Examples

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 Sub Button2_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button2.Click

    If (Color.op_Inequality(Me.BackColor, SystemColors.ControlDark)) Then
        Me.BackColor = SystemColors.ControlDark
    End If
    If Not (Me.Font.Bold) Then
        Me.Font = New Font(Me.Font, FontStyle.Bold)
    End If
End Sub


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);
    }
}


void Button2_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   if ( this->BackColor != SystemColors::ControlDark )
   {
      this->BackColor = SystemColors::ControlDark;
   }

   if (  !(this->Font->Bold) )
   {
      this->Font = gcnew System::Drawing::Font( this->Font,FontStyle::Bold );
   }
}
