Vector.Inequality(Vector, Vector) 操作员

定义

比较两个向量是否不相等。Compares two vectors for inequality.

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

参数

vector1
Vector

要比较的第一个向量。The first vector to compare.

vector2
Vector

要比较的第二个向量。The second vector to compare.

返回

如果 vector1vector2XY 分量不相等,则为 true;否则为 falsetrue if the X and Y components of vector1 and vector2 are different; otherwise, false.

示例

下面的示例演示如何使用此运算符 (! =) 检查两个Vector结构是否不相等。The following example shows how to use this operator (!=) to check whether two Vector structures are not equal.

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

注解

使用Y XDouble描述矢量的和属性。A vector's X and Y properties are described using Double values. 因为在执行算术运算Double时, 的值可能会丢失精度, 因此, 逻辑上相等的Vector两个结构之间的比较可能会失败。Because the value of a Double can lose precision when arithmetic operations are performed on it, a comparison between two Vector structures that are logically equal might fail.
