Examples

The following example shows how to check if two Point structures are not equal. It also illustrates how to assign values to a Point structure when the structure is being declared and after the structure has been declared.

// Checks if two Points are equal using the overloaded inequality operator.
private Boolean pointInequalityExample()
{
    // Checks if two Points are not equal using the overloaded inequality operator.

    // Declaring point1 and initializing x,y values
    Point point1 = new Point(10, 5);

    // Declaring point2 without initializing x,y values
    Point point2 = new Point();

    // Boolean to hold the result of the comparison
    Boolean areNotEqual;

    // assigning values to point2
    point2.X = 15;
    point2.Y = 40;

    // Compare Point structures for equality.
    // areNotEqual is True
    areNotEqual = (point1 != point2);

    return areNotEqual;
}

' Checks if two Points are equal using the overloaded inequality operator.
Private Function pointInequalityExample() As Boolean
    ' Checks if two Points are not equal using the overloaded inequality operator.

    ' Declaring point1 and initializing x,y values
    Dim point1 As New Point(10, 5)

    ' Declaring point2 without initializing x,y values
    Dim point2 As New Point()

    ' Boolean to hold the result of the comparison
    Dim areNotEqual As Boolean

    ' assigning values to point2
    point2.X = 15
    point2.Y = 40

    ' Compare Point structures for equality.
    ' areNotEqual is True
    areNotEqual = (point1 <> point2)

    Return areNotEqual

End Function

Remarks

In XAML, the delimiter between the X and Y values of a Point can be either a comma or a space.

Some cultures might use the comma character as the decimal delimiter instead of the period character. XAML processing for invariant culture defaults to en-US in most XAML processor implementations, and expects the period to be the decimal delimiter. You should avoid using the comma character as the decimal delimiter if specifying a Point in XAML, because that will clash with the string type conversion of a Point attribute value into the X and Y components.

XAML Attribute Usage

<object property="x,y"/>  
-or-  
<object property="x y"/>

XAML Values

x
The x-coordinate of this Point.

y
The y-coordinate of this Point.

Constructors

Point(Double, Double)

Creates a new Point structure that contains the specified coordinates.

Properties

X	Gets or sets the X-coordinate value of this Point structure.
Y	Gets or sets the Y-coordinate value of this Point.

Methods

Add(Point, Vector)	Adds a Vector to a Point and returns the result as a Point structure.
Equals(Object)	Determines whether the specified Object is a Point and whether it contains the same coordinates as this Point.
Equals(Point)	Compares two Point structures for equality.
Equals(Point, Point)	Compares two Point structures for equality.
GetHashCode()	Returns the hash code for this Point.
Multiply(Point, Matrix)	Transforms the specified Point structure by the specified Matrix structure.
Offset(Double, Double)	Offsets a point's X and Y coordinates by the specified amounts.
Parse(String)	Constructs a Point from the specified String.
Subtract(Point, Point)	Subtracts the specified Point from another specified Point and returns the difference as a Vector.
Subtract(Point, Vector)	Subtracts the specified Vector from the specified Point and returns the resulting Point.
ToString()	Creates a String representation of this Point.
ToString(IFormatProvider)	Creates a String representation of this Point.

Operators

Addition(Point, Vector)	Translates the specified Point by the specified Vector and returns the result.
Equality(Point, Point)	Compares two Point structures for equality.
Explicit(Point to Size)	Creates a Size structure with a Width equal to this point's X value and a Height equal to this point's Y value.
Explicit(Point to Vector)	Creates a Vector structure with an X value equal to the point's X value and a Y value equal to the point's Y value.
Inequality(Point, Point)	Compares two Point structures for inequality.
Multiply(Point, Matrix)	Transforms the specified Point by the specified Matrix.
Subtraction(Point, Point)	Subtracts the specified Point from another specified Point and returns the difference as a Vector.
Subtraction(Point, Vector)	Subtracts the specified Vector from the specified Point and returns the resulting Point.
