Properties

	Name	Description
	Count	Gets the number of elements contained in the ReadOnlyCollection<T> instance. (Inherited from ReadOnlyCollection<T>.)

Methods

	Name	Description
	Contains	Determines whether an element is in the ReadOnlyCollection<T>. (Inherited from ReadOnlyCollection<T>.)
	CopyTo	Copies the entire ReadOnlyCollection<T> to a compatible one-dimensional Array, starting at the specified index of the target array. (Inherited from ReadOnlyCollection<T>.)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetEnumerator	Returns an enumerator that iterates through the ReadOnlyCollection<T>. (Inherited from ReadOnlyCollection<T>.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IndexOf	Searches for the specified object and returns the zero-based index of the first occurrence within the entire ReadOnlyCollection<T>. (Inherited from ReadOnlyCollection<T>.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnCollectionChanged	Raises the CollectionChanged event.
	OnPropertyChanged	Raises the PropertyChanged event.

	ICollection::CopyTo	Copies the elements of the ICollection to an Array, starting at a particular Array index. (Inherited from ReadOnlyCollection<T>.)
	ICollection<T>::IsReadOnly	Gets a value indicating whether the ICollection<T> is read-only. (Inherited from ReadOnlyCollection<T>.)
	ICollection::IsSynchronized	Gets a value indicating whether access to the ICollection is synchronized (thread safe). (Inherited from ReadOnlyCollection<T>.)
	ICollection<T>::Remove	Removes the first occurrence of a specific object from the ICollection<T>. This implementation always throws NotSupportedException. (Inherited from ReadOnlyCollection<T>.)
