``````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``

## 例

2つの構造体が等しいかどうかを確認する方法を次の例に示し Vector ます。The following example shows how to check two Vector structures for equality.

``````// 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
