Point.Y 屬性

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

public double Y { get; set; }

member this.Y : double with get, set

Public Property Y As Double

屬性值

Double

這個 Y 結構的 Point 座標值。The Y-coordinate value of this Point structure. 預設值為 0。The default value is 0.

範例

下列範例顯示如何檢查兩個結構是否 Point 不相等。The following example shows how to check if two Point structures are not equal. 它也會說明如何 Point 在宣告結構時，以及在宣告結構之後，將值指派給結構。It also illustrates how to assign values to a Point structure when the structure is being declared and after the structure has been declared.

// Checks if two Points are equal using the overloaded inequality operator.
private Boolean pointInequalityExample()
{
    // Checks if two Points are not equal using the overloaded inequality operator.

    // Declaring point1 and initializing x,y values
    Point point1 = new Point(10, 5);

    // Declaring point2 without initializing x,y values
    Point point2 = new Point();

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

    // assigning values to point2
    point2.X = 15;
    point2.Y = 40;

    // Compare Point structures for equality.
    // areNotEqual is True
    areNotEqual = (point1 != point2);

    return areNotEqual;
}

' Checks if two Points are equal using the overloaded inequality operator.
Private Function pointInequalityExample() As Boolean
    ' Checks if two Points are not equal using the overloaded inequality operator.

    ' Declaring point1 and initializing x,y values
    Dim point1 As New Point(10, 5)

    ' Declaring point2 without initializing x,y values
    Dim point2 As New Point()

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

    ' assigning values to point2
    point2.X = 15
    point2.Y = 40

    ' Compare Point structures for equality.
    ' areNotEqual is True
    areNotEqual = (point1 <> point2)

    Return areNotEqual

End Function
