Class ResourceDictionary

Defines a dictionary that contains resources used by components of the app. This dictionary is oriented toward defining the resources in XAML, and then retrieving them through XAML references via the StaticResource markup extension. Alternatively you can access resources by traversing the dictionary at run time.

Methods

Add(Object, Object)

Adds an item to the ResourceDictionary.

Declaration

public void Add(object key, object value)

Parameters

Type	Name	Description
System.Object	key	The string key of the item to add.
System.Object	value	The item value to add.

Exceptions

Type	Condition
System.NotSupportedException	Attempted to add null as a value.
System.ArgumentException	Attempted to add an item with a key that already exists in this ResourceDictionary.-or-Attempted to use a key that is not a string.

Add(String, Object)

Declaration

public void Add(string key, object value)

Parameters

Type	Name	Description
System.String	key
System.Object	value

BeginInit()

Mark the begining of the Init phase

Declaration

public void BeginInit()

Remarks

BeginInit and EndInit follow a transaction model. BeginInit marks the dictionary uninitialized and EndInit marks it initialized.

Clear()

Removes all items from this ResourceDictionary.

Declaration

public void Clear()

Contains(Object)

Returns a value that indicates whether a specified key exists in the ResourceDictionary.

Declaration

public bool Contains(object key)

Parameters

Type	Name	Description
System.Object	key	The key to check for in the ResourceDictionary.

Returns

Type	Description
System.Boolean	true if an item with that key exists in the ResourceDictionary; otherwise, false.

Exceptions

Type	Condition
System.ArgumentNullException	key is null.

ContainsKey(Object)

Contains(Object)

Declaration

public bool ContainsKey(object key)

Parameters

Type	Name	Description
System.Object	key

Returns

Type	Description
System.Boolean

CopyTo(Array, Int32)

Copies the elements of the ResourceDictionary to an System.Array, starting at a particular System.Array index.

Declaration

public void CopyTo(Array array, int index)

Parameters

Type	Name	Description
System.Array	array	The one-dimensional System.Array that is the destination of the elements copied from ResourceDictionary. The System.Array must have zero-based indexing.

CopyTo(DictionaryEntry[], Int32)

Copies the dictionary's elements to a one-dimensional Array instance at the specified index.

Declaration

public void CopyTo(DictionaryEntry[] array, int arrayIndex)

Parameters
