Vector3D.Inequality(Vector3D, Vector3D) 運算子

定義

比較兩個 Vector3D 結構是否相等。Compares two Vector3D structures for inequality.

public:
 static bool operator !=(System::Windows::Media::Media3D::Vector3D vector1, System::Windows::Media::Media3D::Vector3D vector2);
public static bool operator != (System.Windows.Media.Media3D.Vector3D vector1, System.Windows.Media.Media3D.Vector3D vector2);
static member op_Inequality : System.Windows.Media.Media3D.Vector3D * System.Windows.Media.Media3D.Vector3D -> bool
Public Shared Operator != (vector1 As Vector3D, vector2 As Vector3D) As Boolean

參數

vector1
Vector3D

要比較的第一個 Vector3D 結構。The first Vector3D structure to compare.

vector2
Vector3D

要比較的第二個 Vector3D 結構。The second Vector3D structure to compare.

傳回

如果 vector3D1vector3D2XYZ 元件不同則為 true,否則為 falsetrue if the X, Y, and Z components of vector3D1 and vector3D2 are different; false otherwise.

範例

下列範例顯示如何使用多載不等比較運算子來檢查兩個Vector3D結構是否不相等。The following example shows how to use the overloaded inequality operator to check if two Vector3D structures are not equal.

// Checks if two Vector3D structures are not equal using the overloaded inequality operator.

Vector3D vector1 = new Vector3D(20, 30, 40);
Vector3D vector2 = new Vector3D(45, 70, 80);
Boolean areNotEqual;

areNotEqual = (vector1 != vector2);
// areNotEqual is True
' Checks if two Vector3D structures are not equal using the overloaded inequality operator.

Dim vector1 As New Vector3D(20, 30, 40)
Dim vector2 As New Vector3D(45, 70, 80)
Dim areNotEqual As Boolean

areNotEqual = (vector1 <> vector2)
' areNotEqual is True

備註

如果Vector3DXY和屬性Z的值不同, 則兩個結構不相等。Two Vector3D structures are not equal if the values of their X, Y, and Z properties are different.

Vector3D值會使用Double值來描述。Vector3D values are described using Double values. 當運算時, 的Double值可能會失去有效位數, 因此在邏輯上Vector3D相等的兩個值之間的比較可能會失敗。Because the value of a Double can lose precision when operated upon, a comparison between two Vector3D values that are logically equal might fail.
