CornerRadius Structure

.NET Framework (current version)

Other Versions

Represents the radii of a rectangle's corners.

Namespace: System.Windows
Assembly: PresentationFramework (in PresentationFramework.dll)

Syntax

C++

[TypeConverterAttribute((CornerRadiusConverter^::typeid))]
public value struct CornerRadius : IEquatable<CornerRadius>

Constructors

	Name	Description
	CornerRadius(Double)	Initializes a new instance of the CornerRadius class with a specified uniform radius value for every corner or the rectangle.
	CornerRadius(Double, Double, Double, Double)	Initializes a new instance of the CornerRadius class with the specified radius values for each corner of the rectangle.

Properties

	Name	Description
	BottomLeft	Gets or sets the radius of the bottom-left corner.
	BottomRight	Gets or sets the radius of the bottom-right corner.
	TopLeft	Gets or sets the radius of the top-left corner.
	TopRight	Gets or sets the radius of the top-right corner.

Methods

	Name	Description
	Equals(CornerRadius)	Compares two CornerRadius structures for equality.
	Equals(Object^)	Determines whether the specified Object is a CornerRadius and whether it contains the same corner radius values as this CornerRadius. (Overrides ValueType::Equals(Object^).)
	GetHashCode()	Returns the hash code for this CornerRadius. (Overrides ValueType::GetHashCode().)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	ToString()	Returns the string representation of the CornerRadius. (Overrides ValueType::ToString().)

Operators

	Name	Description
	Equality(CornerRadius, CornerRadius)	Compares two CornerRadius structures for equality.
	Inequality(CornerRadius, CornerRadius)	Compares two CornerRadius structures for inequality.

This class has four properties, TopLeft, TopRight, BottomLeft, and BottomRight, corresponding to the individual corners of the rectangle. Each is a Double structure that can be set independently of the others.

The radii cannot be negative.

XAML Attribute Usage

<object property="TopLeft,TopRight,BottomRight,BottomLeft "/>
- or -
<object property="AllCorners"/>

XAML Values

TopLeft: Double value that specifies the radius of the top left corner.
TopRight: Double value that specifies the top right corner.
BottomRight: Double value that specifies the bottom right corner.
BottomLeft: Double value that specifies the bottom left corner.
AllCorners: If only a single Double value is specified, that measure is applied to ALL of the TopLeft, TopRight, BottomRight, and BottomLeft corners of the CornerRadius.

Note
Values need not include the decimal point explicitly when specified as a string. The string "1" provided in XAML evaluates to a value of 1.0 when referenced in code.

Examples

The following example shows how to set the value of the CornerRadius property by using Extensible Application Markup Language (XAML) and code.

C++

No code example is currently available or this language may not be supported.

XAML

<Border BorderBrush="SlateBlue" BorderThickness="5,10,15,20" Background="AliceBlue" Padding="5" CornerRadius="15">
