Type Parameters

  • TSourceCollection
    The type of the source collection that this collection wraps.
  • TSourceElement
    The type of the elements in the source collection.
  • TTargetElement
    The type of the transformed elements in this collection.

The TransformedCollection<TSourceCollection, TSourceElement, TTargetElement> type exposes the following members.

Constructors

  Name Description
Public method TransformedCollection<TSourceCollection, TSourceElement, TTargetElement> Creates a new transformed collection wrapping a source collection.

Properties

  Name Description
Public property Count Gets the number of elements contained in the ReadOnlyCollection<T> instance. (Inherited from ReadOnlyCollection<TTargetElement>.)
Public property Item Gets the element at the specified index. (Inherited from ReadOnlyCollection<TTargetElement>.)
Protected property Items Returns the IList<T> that the ReadOnlyCollection<T> wraps. (Inherited from ReadOnlyCollection<TTargetElement>.)

Methods

  Name Description
Public method Contains Determines whether an element is in the ReadOnlyCollection<T>. (Inherited from ReadOnlyCollection<TTargetElement>.)
Public method CopyTo Copies the entire ReadOnlyCollection<T> to a compatible one-dimensional Array, starting at the specified index of the target array. (Inherited from ReadOnlyCollection<TTargetElement>.)
Public method Dispose() Tears down all elements of the transformed collection, clears the transformed collection, and stops listening to change events on the source collection.
Protected method Dispose(Boolean)
Public method Equals Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetEnumerator Returns an enumerator that iterates through the ReadOnlyCollection<T>. (Inherited from ReadOnlyCollection<TTargetElement>.)
Public method GetHashCode Serves as the default hash function. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method IndexOf Searches for the specified object and returns the zero-based index of the first occurrence within the entire ReadOnlyCollection<T>. (Inherited from ReadOnlyCollection<TTargetElement>.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Protected method OnCollectionChanged
Protected method OnPropertyChanged
Protected method ReceiveWeakEvent
Public method ToString Returns a string that represents the current object. (Inherited from Object.)

Events

  Name Description
Public event CollectionChanged Occurs when the collection changes.
Public event PropertyChanged Occurs when a property changes.
