Attributes

TypeConverterAttribute

Implements

ICollection<Double> ICollection<T> IEnumerable<Double> IEnumerable<T> IList<Double> ICollection IEnumerable IList IFormattable

Remarks

Members of this class behave exactly as described by the IList<T>, ICollection<T>, and IEnumerable<T> documentation, except that this implementation throws an ArgumentException if you attempt to insert null into the collection.

Freezable Features: Because it inherits from the Freezable class, the DoubleCollection class provides several special features: DoubleCollection objects can be declared as resources, shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. For more information about the different features provided by Freezable objects, see the Freezable Objects Overview.

XAML Attribute Usage

<object property="oneOrMoreDoubleValues"/>  

XAML Values

oneOrMoreDoubleValues
One or more Double values, with each pair delimited by a single comma and/or one or more spaces:

Double[delimiterDouble]*

For example, "0.5 1.0 43" and "0.5,1.0,43" are both valid.

Constructors

DoubleCollection()	Initializes a new instance of the DoubleCollection class.
DoubleCollection(IEnumerable<Double>)	Initializes a new instance of the DoubleCollection class with the specified collection of Double values.
DoubleCollection(Int32)	Initializes a new instance of the DoubleCollection class with the specified capacity, or the number of Double values the collection is initially capable of storing.

Properties

CanFreeze	Gets a value that indicates whether the object can be made unmodifiable. (Inherited from Freezable)
Count	Gets the number of doubles contained in the DoubleCollection.
DependencyObjectType	Gets the DependencyObjectType that wraps the CLR type of this instance. (Inherited from DependencyObject)
Dispatcher	Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject)
IsFrozen	Gets a value that indicates whether the object is currently modifiable. (Inherited from Freezable)
IsSealed	Gets a value that indicates whether this instance is currently sealed (read-only). (Inherited from DependencyObject)
Item[Int32]	Gets or sets the Double at the specified zero-based index.

Methods

Add(Double)	Adds a Double to the end of this DoubleCollection.
CheckAccess()	Determines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject)
Clear()	Removes all the items from this DoubleCollection.
ClearValue(DependencyProperty)	Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject)
ClearValue(DependencyPropertyKey)	Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject)
Clone()	Creates a modifiable clone of this DoubleCollection, making deep copies of this object's values. When copying dependency properties, this method copies resource references and data bindings (but they might no longer resolve) but not animations or their current values.
CloneCore(Freezable)	Makes the instance a clone (deep copy) of the specified Freezable using base (non-animated) property values. (Inherited from Freezable)
CloneCurrentValue()	Creates a modifiable clone of this DoubleCollection object, making deep copies of this object's current values. Resource references, data bindings, and animations are not copied, but their current values are.
CloneCurrentValueCore(Freezable)	Makes the instance a modifiable clone (deep copy) of the specified Freezable using current property values. (Inherited from Freezable)
CoerceValue(DependencyProperty)	Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject. (Inherited from DependencyObject)
Contains(Double)	Determines whether a Double is in this DoubleCollection.
CopyTo(Double[], Int32)	Copies the items of this DoubleCollection, starting with the specified index, into an array of Double values.
CreateInstance()	Initializes a new instance of the Freezable class. (Inherited from Freezable)
CreateInstanceCore()	When implemented in a derived class, creates a new instance of the Freezable derived class. (Inherited from Freezable)
Equals(Object)	Determines whether a provided DependencyObject is equivalent to the current DependencyObject. (Inherited from DependencyObject)
Freeze()	Makes the current object unmodifiable and sets its IsFrozen property to true. (Inherited from Freezable)
FreezeCore(Boolean)	Makes the Freezable object unmodifiable or tests whether it can be made unmodifiable. (Inherited from Freezable)
GetAsFrozen()	Creates a frozen copy of the Freezable, using base (non-animated) property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (Inherited from Freezable)
GetAsFrozenCore(Freezable)	Makes the instance a frozen clone of the specified Freezable using base (non-animated) property values. (Inherited from Freezable)
GetCurrentValueAsFrozen()	Creates a frozen copy of the Freezable using current property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (Inherited from Freezable)
GetCurrentValueAsFrozenCore(Freezable)	Makes the current instance a frozen clone of the specified Freezable. If the object has animated dependency properties, their current animated values are copied. (Inherited from Freezable)
GetEnumerator()	Returns an enumerator that can iterate through the collection.
GetHashCode()	Gets a hash code for this DependencyObject. (Inherited from DependencyObject)
GetLocalValueEnumerator()	Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject)
GetType()	Gets the Type of the current instance. (Inherited from Object)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject)
IndexOf(Double)	Gets the index of the first occurrence of the specified Double.
Insert(Int32, Double)	Inserts a Double into this DoubleCollection at the specified index.
InvalidateProperty(DependencyProperty)	Re-evaluates the effective value for the specified dependency property. (Inherited from DependencyObject)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnChanged()	Called when the current Freezable object is modified. (Inherited from Freezable)
OnFreezablePropertyChanged(DependencyObject, DependencyObject, DependencyProperty)	This member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code. (Inherited from Freezable)
OnFreezablePropertyChanged(DependencyObject, DependencyObject)	Ensures that appropriate context pointers are established for a DependencyObjectType data member that has just been set. (Inherited from Freezable)
OnPropertyChanged(DependencyPropertyChangedEventArgs)	Overrides the DependencyObject implementation of OnPropertyChanged(DependencyPropertyChangedEventArgs) to also invoke any Changed handlers in response to a changing dependency property of type Freezable. (Inherited from Freezable)
Parse(String)	Converts a String representation of a collection of doubles into an equivalent DoubleCollection.
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject)
ReadPreamble()	Ensures that the Freezable is being accessed from a valid thread. Inheritors of Freezable must call this method at the beginning of any API that reads data members that are not dependency properties. (Inherited from Freezable)
Remove(Double)	Removes the first occurrence of the specified Double from this DoubleCollection.
RemoveAt(Int32)	Removes the Double at the specified index from this DoubleCollection.
SetCurrentValue(DependencyProperty, Object)	Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject)
SetValue(DependencyPropertyKey, Object)	Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject)
ShouldSerializeProperty(DependencyProperty)	Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property. (Inherited from DependencyObject)
ToString()	Creates a String representation of this DoubleCollection.
ToString(IFormatProvider)	Creates a String representation of this DoubleCollection.
VerifyAccess()	Enforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject)
WritePostscript()	Raises the Changed event for the Freezable and invokes its OnChanged() method. Classes that derive from Freezable should call this method at the end of any API that modifies class members that are not stored as dependency properties. (Inherited from Freezable)
WritePreamble()	Verifies that the Freezable is not frozen and that it is being accessed from a valid threading context. Freezable inheritors should call this method at the beginning of any API that writes to data members that are not dependency properties. (Inherited from Freezable)

Events

Changed

Occurs when the Freezable or an object it contains is modified. (Inherited from Freezable)
