## 定義

``````public:
static bool operator ==(System::Windows::Media::Media3D::Point4D point1, System::Windows::Media::Media3D::Point4D point2);``````
``public static bool operator == (System.Windows.Media.Media3D.Point4D point1, System.Windows.Media.Media3D.Point4D point2);``
``static member ( = ) : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Point4D -> bool``
``Public Shared Operator == (point1 As Point4D, point2 As Point4D) As Boolean``

point1
Point4D

point2
Point4D

Boolean

## 範例

``````// Checks if two Point4D structures are equal using the overloaded equality operator.

## 備註

Point4D如果其 XY 、和屬性的值相同，則兩個結構相等 Z WTwo Point4D structures are equal if the values of their X, Y, Z, and W properties are the same.
