DrawingAttributes.Equality(DrawingAttributes, DrawingAttributes) 运算符

定义

命名空间:

System.Windows.Ink

程序集:

PresentationCore.dll

确定指定的 DrawingAttributes 对象是否相等。

public:
 static bool operator ==(System::Windows::Ink::DrawingAttributes ^ first, System::Windows::Ink::DrawingAttributes ^ second);

public static bool operator == (System.Windows.Ink.DrawingAttributes first, System.Windows.Ink.DrawingAttributes second);

static member ( = ) : System.Windows.Ink.DrawingAttributes * System.Windows.Ink.DrawingAttributes -> bool

Public Shared Operator == (first As DrawingAttributes, second As DrawingAttributes) As Boolean

参数

first

DrawingAttributes

要比较的第一个 DrawingAttributes 对象。

second

DrawingAttributes

要比较的第二个 DrawingAttributes 对象。

返回

Boolean

如果对象相同，则为 true；否则为 false。

示例

以下示例比较两 DrawingAttributes 个 对象的相等性。 Color由于 和 attributes2 上的 attributes1 、StylusTip、 Height和 Width 属性设置为相同的值，因此将显示“DrawingAttributes 相等”消息。

DrawingAttributes attributes1 = new DrawingAttributes();
attributes1.Color = Colors.Blue;
attributes1.StylusTip = StylusTip.Rectangle;
attributes1.Height = 5;
attributes1.Width = 5;

DrawingAttributes attributes2 = new DrawingAttributes();
attributes2.Color = Colors.Blue;
attributes2.StylusTip = StylusTip.Rectangle;
attributes2.Height = 5;
attributes2.Width = 5;

Dim attributes1 As New DrawingAttributes()
attributes1.Color = Colors.Blue
attributes1.StylusTip = StylusTip.Rectangle
attributes1.Height = 5
attributes1.Width = 5

Dim attributes2 As New DrawingAttributes()
attributes2.Color = Colors.Blue
attributes2.StylusTip = StylusTip.Rectangle
attributes2.Height = 5
attributes2.Width = 5

if (attributes1 == attributes2)
{
    MessageBox.Show("The DrawingAttributes are equal");
}
else
{
    MessageBox.Show("The DrawingAttributes are not equal");
}

If attributes1 = attributes2 Then
    MessageBox.Show("The DrawingAttributes are equal")
Else
    MessageBox.Show("The DrawingAttributes are not equal")
End If

注解

如果以下属性相等，则两 DrawingAttributes 个 对象相等：

• Color

• FitToCurve

• Height

• IgnorePressure

• IsHighlighter

• StylusTip

• StylusTipTransform

• Width

注意

方法 Equality 不检查自定义属性是否相等。
