Vector.X 属性

定义

命名空间:

System.Windows

程序集:

WindowsBase.dll

获取或设置此向量的 X 分量。

public:
 property double X { double get(); void set(double value); };

public double X { get; set; }

member this.X : double with get, set

Public Property X As Double

属性值

Double

此向量的 X 分量。 默认值为 0。

示例

以下示例演示如何检查两个 Vector 结构是否相等。

// Checks if two Vectors are equal using the overloaded equality operator.
private Boolean vectorEqualityExample()
{

    // Declaring vecto1 and initializing x,y values
    Vector vector1 = new Vector(20, 30);

    // Declaring vector2 without initializing x,y values
    Vector vector2 = new Vector();

    // Boolean to hold the result of the comparison
    Boolean areEqual;

    // assigning values to vector2
    vector2.X = 45;
    vector2.Y = 70;

    // Comparing Vectors for equality
    // areEqual is False
    areEqual = (vector1 == vector2);

    return areEqual;
}

' Checks if two Vectors are equal using the overloaded equality operator.
Private Function vectorEqualityExample() As Boolean

    ' Declaring vecto1 and initializing x,y values
    Dim vector1 As New Vector(20, 30)

    ' Declaring vector2 without initializing x,y values
    Dim vector2 As New Vector()

    ' Boolean to hold the result of the comparison
    Dim areEqual As Boolean

    ' assigning values to vector2
    vector2.X = 45
    vector2.Y = 70

    ' Comparing Vectors for equality
    ' areEqual is False
    areEqual = (vector1 = vector2)

    Return areEqual

End Function
