比較兩個 Point4D 結構是否相等。
public:
static bool operator !=(System::Windows::Media::Media3D::Point4D point1, System::Windows::Media::Media3D::Point4D point2);C#
public static bool operator != (System.Windows.Media.Media3D.Point4D point1, System.Windows.Media.Media3D.Point4D point2);static member op_Inequality : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Point4D -> boolPublic Shared Operator != (point1 As Point4D, point2 As Point4D) As Boolean如果 point4D1 和 point4D2 的 X、Y、Z 和 W 座標不同則為 true，否則為 false。
下列範例示範如何使用多載不等比較運算子來檢查兩 Point4D 個結構是否不相等。
C#
// Checks if two Point4Ds are not equal using the overloaded inequality operator.
Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
Boolean areNotEqual;
areNotEqual = (point1 != point2);
// areNotEqual is True
// Displaying Results
syntaxString = "areNotEqual = (point1 != point2);";
resultType = "Boolean";
operationString = "Checking if two 3D points are not equal";
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString);
' Checks if two Point4Ds are not equal using the overloaded inequality operator.
Dim point1 As New Point4D(10, 5, 1, 4)
Dim point2 As New Point4D(15, 40, 60, 75)
Dim areNotEqual As Boolean
areNotEqual = (point1 <> point2)
' areNotEqual is True
' Displaying Results
syntaxString = "areNotEqual = (point1 != point2)"
resultType = "Boolean"
operationString = "Checking if two 3D points are not equal"
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString)
如果 、 Y 、 Z 和 W 屬性的值不同，則兩 Point4D 個 X 結構不相等。
Double由於在算數運算上執行算數運算時，值可能會失去有效位數，因此邏輯上相等的兩 Point4D 個值之間的比較可能會失敗。
