Point Constructors

Definition

Namespace:

System.Drawing

Assemblies:

netstandard.dll, System.Drawing.Primitives.dll

Initializes a new instance of the Point struct with the specified coordinates.

Overloads

Point(Size)	Initializes a new instance of the Point struct from a Size.
Point(Int32)	Initializes a new instance of the Point struct using coordinates specified by an integer value.
Point(Int32, Int32)	Initializes a new instance of the Point struct with the specified coordinates.

Point(Size)

Source:

Point.cs

Initializes a new instance of the Point struct from a Size.

C#

public Point(System.Drawing.Size sz);

Parameters

sz

Size

A Size that specifies the coordinates for the new Point.

Examples

The following code example demonstrates how to use the Equality operator and how to construct a Point from a Size or two integers. It also demonstrates how to use the X and Y properties. This example is designed to be used with Windows Forms. Paste the code into a form that contains a button named Button1, and associate the Button1_Click method with the button's Click event.

C#

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)
    {
        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}),
            this.Font, Brushes.Black, new PointF(10, 70));
    }
}

Point(Int32)

Source:

Point.cs

Initializes a new instance of the Point struct using coordinates specified by an integer value.

C#

public Point(int dw);

Parameters

dw

Int32

A 32-bit integer that specifies the coordinates for the new Point.

Examples

The following code example demonstrates how to use the Point and Size.Size constructors and the System.Drawing.ContentAlignment enumeration. To run this example, paste this code into a Windows Form that contains a label named Label1, and call the InitializeLabel1 method in the form's constructor.

C#

private void 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
    // (using hexadecimal).
    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";
}

Remarks

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)

Source:

Point.cs

Initializes a new instance of the Point struct with the specified coordinates.

C#

public Point(int x, int y);

Parameters

x

Int32

The horizontal position of the point.

y

Int32

The vertical position of the point.

    {
        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}),
            this.Font, Brushes.Black, new PointF(10, 70));
    }
