Point.X 属性
获取或设置此 Point 的 X 坐标。
**命名空间:**System.Drawing
**程序集:**System.Drawing（在 system.drawing.dll 中）
语法
声明
Public Property X As Integer
用法
Dim instance As Point
Dim value As Integer
value = instance.X
instance.X = value
public int X { get; set; }
public:
property int X {
int get ();
void set (int value);
}
/** @property */
public int get_X ()
/** @property */
public void set_X (int value)
public function get X () : int
public function set X (value : int)
属性值
此 Point 的 X 坐标。
示例
下面的代码示例演示如何使用 op_Equality 运算符以及如何从 Size 或两个整数构造 Point。此示例还演示如何使用 X 和 Y 属性。此示例是针对使用 Windows 窗体而设计的。将代码粘贴到一个窗体中（该窗体包含一个名为 Button1 的按钮），然后将 Button1_Click 方法与该按钮的 Click 事件关联。
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}", _
