# Point 建構函式

## 多載

 Point(Size) 從 Point 初始化 Size 類別的新執行個體。Initializes a new instance of the Point class from a Size. Point(Int32) 使用由整數值指定的座標，初始化 Point 類別的新執行個體。Initializes a new instance of the Point class using coordinates specified by an integer value. Point(Int32, Int32) 使用指定的座標，初始化 Point 類別的新執行個體。Initializes a new instance of the Point class with the specified coordinates.

## Point(Size)

Point 初始化 Size 類別的新執行個體。Initializes a new instance of the Point class from a Size.

``````public:
Point(System::Drawing::Size sz);``````
``public Point (System.Drawing.Size sz);``
``new System.Drawing.Point : System.Drawing.Size -> System.Drawing.Point``
``Public Sub New (sz As Size)``

#### 參數

sz
Size

Size，指定新 Point 的座標。A Size that specifies the coordinates for the new Point.

## Point(Int32)

``````public:
Point(int dw);``````
``public Point (int dw);``
``new System.Drawing.Point : int -> System.Drawing.Point``
``Public Sub New (dw As Integer)``

#### 參數

dw
Int32

32 位元整數，指定新 Point 的座標。A 32-bit integer that specifies the coordinates for the new Point.

### 範例

``````void InitializeLabel1()
{
// Set a border.
Label1->BorderStyle = BorderStyle::FixedSingle;

// Set the size, constructing a size from two integers.
Label1->Size = System::Drawing::Size( 100, 50 );

// Set the location, constructing a point from a 32-bit integer
Label1->Location = Point(0x280028);

// Set and align the text on the lower-right side of the label.
Label1->TextAlign = ContentAlignment::BottomRight;
Label1->Text = "Bottom Right Alignment";
}
``````
``````private void InitializeLabel1()

// Set a border.

// Set the size, constructing a size from two integers.
Label1.Size = new Size(100, 50);

// Set the location, constructing a point from a 32-bit integer
Label1.Location = new Point(0x280028);

// Set and align the text on the lower-right side of the label.
Label1.TextAlign = ContentAlignment.BottomRight;
Label1.Text = "Bottom Right Alignment";

``````
``````Private Sub InitializeLabel1()

' Set a border.
Label1.BorderStyle = BorderStyle.FixedSingle

' Set the size, constructing a size from two integers.
Label1.Size = New Size(100, 50)

' Set the location, constructing a point from a 32-bit integer

' Set and align the text on the lower-right side of the label.

Label1.Text = "Bottom Right Alignment"

``````

### 備註

`dw` 參數的低序位16位會指定水準 x 座標，而較高的16個位則指定新 Point的垂直 y 座標。The low-order 16 bits of the `dw` parameter specify the horizontal x-coordinate and the higher 16 bits specify the vertical y-coordinate for the new Point.

## Point(Int32, Int32)

``````public:
Point(int x, int y);``````
``public Point (int x, int y);``
``new System.Drawing.Point : int * int -> System.Drawing.Point``
``Public Sub New (x As Integer, y As Integer)``

x
Int32

y
Int32
