Point.X プロパティ

この Point の x 座標を取得または設定します。

名前空間: System.Drawing
アセンブリ: System.Drawing (system.drawing.dll 内)
構文

Visual Basic (宣言)

Public Property X As Integer

Visual Basic (使用法)

Dim instance As Point
Dim value As Integer

value = instance.X

instance.X = value

public int X { get; set;
 }

C++

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

/** @property */
public int get_X ()

/** @property */
public void set_X (int value)

JScript

public function get X ()
 : int

public function set X (value
 : int)

プロパティ値
この Point の x 座標。

使用例

op_Equality 演算子を使用する方法と、Size または 2 つの整数から Point を生成する方法を次のコード例に示します。また、X プロパティと Y プロパティの使用方法も示します。この例は、Windows フォームでの使用を意図してデザインされています。Button1 という名前のボタンが配置されているフォームにコードを貼り付け、Button1_Click メソッドをボタンの Click イベントに関連付けます。

Visual Basic

Private Sub Button1_Click(ByVal
 sender As System.Object, _
    ByVal e As System.EventArgs) Handles
 Button1.Click

    ' Construct a new Point with integers.
    Dim Point1 As New Point(100,
 100)

    ' Create a Graphics object.
    Dim formGraphics As Graphics = Me.CreateGraphics()

    ' Construct another Point, this time using a Size.
    Dim Point2 As New Point(New
 Size(100, 100))

    ' Call the equality operator to see if the points are equal,  
    ' and if so print out their x and y values.
    If (Point.op_Equality(Point1, Point2)) Then
        formGraphics.DrawString(String.Format("Point1.X:
 " & _
            "{0},Point2.X: {1}, Point1.Y: {2}, Point2.Y {3}",
 _
            New Object() {Point1.X, Point2.X,
 Point1.Y, Point2.Y}), _
            Me.Font, Brushes.Black, New PointF(10,
 70))
    End If

End Sub

private void Button1_Click(System.Object sender,
 System.EventArgs e)
{

    // Construct a new Point with integers.
    Point Point1 = new Point(100, 100);

    // Create a Graphics object.
    Graphics formGraphics = this.CreateGraphics();

    // Construct another Point, this time using a Size.
    Point Point2 = new Point(new Size(100,
 100));

    // Call the equality operator to see if the points are equal,  
    // and if so print out their x and y values.
    if (Point1 == Point2)
