Vector.Inequality(Vector, Vector) 運算子

定義

命名空間:
System.Windows
組件:
WindowsBase.dll

比較兩個不平等向量。

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

參數

vector1
Vector

要比較的第一個向量。

vector2
Vector

要比較的第二個向量。

傳回

Boolean

true若X與Y的 vector1 與 vector2 成分不同;否則， false。

範例

以下範例展示了如何使用此運算子（！=）來檢查兩個 Vector 結構是否不相等。

private Boolean overloadedInequalityOperatorExample()
{
    Vector vector1 = new Vector(20, 30);
    Vector vector2 = new Vector(45, 70);
    Boolean areNotEqual;

    // Check whether the two Vectors are not equal, using the overloaded 
    // inequality operator.
    // areNotEqual is True.
    areNotEqual = (vector1 != vector2);

    return areNotEqual;
}

Private Function overloadedInequalityOperatorExample() As Boolean
    Dim vector1 As New Vector(20, 30)
    Dim vector2 As New Vector(45, 70)
    Dim areNotEqual As Boolean

    ' Check whether the two Vectors are not equal, using the overloaded 
    ' inequality operator.
    ' areNotEqual is True.
    areNotEqual = (vector1 <> vector2)

    Return areNotEqual

End Function

備註

向量的XY性質是用Double值來描述的。 由於 的 Double 值在運算時可能會失去精度，因此 Vector 兩個邏輯相等的結構比較可能會失敗。
