NameDescription
System_CAPS_pubmethod RuntimeNamePropertyAttribute

Initializes a new instance of the RuntimeNamePropertyAttribute class.

NameDescription
System_CAPS_pubproperty

Gets the name of the runtime name property that is specified by this RuntimeNamePropertyAttribute.

System_CAPS_pubproperty

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethod Equals

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod GetHashCode

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod IsDefaultAttribute

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethod Match

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The property that is specified in the RuntimeNamePropertyAttribute must be of type String and must be read/write.

Frameworks might attribute a certain property of one its architectural base elements to be the XAML name equivalent. This is done so that the concept of a XAML name in a XAML namescope set at XAML load time is available to a framework's programming model at run time.

A XAML name value must use the XamlName Grammar.

In previous versions of the .NET Framework, this class existed in the WPF-specific assembly WindowsBase. In .NET Framework 4, RuntimeNamePropertyAttribute is in the System.Xaml assembly. For more information, see Types Migrated from WPF to System.Xaml.

An example of an existing class in Windows Presentation Foundation (WPF) where the RuntimeNamePropertyAttribute is applied is FrameworkElement. The  property on FrameworkElement is attributed with RuntimeNamePropertyAttribute, which results in any FrameworkElement derived class also using as its run-time name property.

In general, you do not typically need to apply this attribute in WPF unless you are implementing a new or FrameworkElement-parallel framework-level class. x:Name should take precedence over the run-time name property if both exist as attributes on an element, and a XAML processor implementation generally throws in this case.
