Vector.Equality(Vector, Vector) 運算子

定義

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

比較兩個向量以求相等。

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 ( = ) : 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 和 的Yvector1分vector2量相等;否則 。 false

範例

以下範例說明如何使用此運算子（==）來檢查兩個 Vector 結構是否相等。

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

    // If the two vectors are equal, areEqual is True,
    // otherwise it is False. In this example it is False.
    Boolean areEqual = (vector1 == vector2);

    return areEqual;
}

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

    ' If the two vectors are equal, areEqual is True,
    ' otherwise it is False. In this example it is False.
    Dim areEqual As Boolean = (vector1 = vector2)

    Return areEqual

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。
