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.
