Properties

	Name	Description
	Count	Gets the number of elements contained in the ReadOnlyCollectionT instance. (Inherited from ReadOnlyCollectionTValue.)
	IsReadOnly	Returns true.
	ItemInt32	Gets the element at the specified index. (Inherited from ReadOnlyCollectionTValue.)
	ItemTKey	Gets or sets the element with the specified key.
	Items	Returns the IListT that the ReadOnlyCollectionT wraps. (Inherited from ReadOnlyCollectionTValue.)
	Keys	Gets an ICollectionT containing the keys of the IDictionaryTKey, TValue.
	Values	Gets an ICollectionT containing the values in the IDictionaryTKey, TValue.

Methods

	Name	Description
	Add(KeyValuePairTKey, TValue)	This method is not supported, as this is a read-only collection.
	Add(KeyValuePairTValue, TKey)	This method is not supported, as this is a read-only collection.
	Add(TKey, TValue)	This method is not supported, as this is a read-only collection.
	Clear	Not supported.
	Contains(T)	Determines whether an element is in the ReadOnlyCollectionT. (Inherited from ReadOnlyCollectionTValue.)
	Contains(KeyValuePairTKey, TValue)	Determines whether the ICollectionT contains a specific value.
	ContainsKey	Determines whether the IDictionaryTKey, TValue contains an element with the specified key.
	CopyTo(T, Int32)	Copies the entire ReadOnlyCollectionT to a compatible one-dimensional Array, starting at the specified index of the target array. (Inherited from ReadOnlyCollectionTValue.)
	CopyTo(KeyValuePairTKey, TValue, Int32)	Copies the elements of the ICollection to an Array, starting at a particular Array index.
	Equals	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 it is reclaimed by garbage collection. (Inherited from Object.)
	GetEnumerator	Returns an enumerator that iterates through the ReadOnlyCollectionT. (Inherited from ReadOnlyCollectionTValue.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetKeyForItem	When implemented in a derived class, extracts the key from the specified element.
	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 ReadOnlyCollectionT. (Inherited from ReadOnlyCollectionTValue.)
	Insert	This method is not supported, as this is a read-only collection.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Remove(KeyValuePairTKey, TValue)	This method is not supported, as this is a read-only collection.
	Remove(TKey)	This method is not supported, as this is a read-only collection.
	RemoveAt	This method is not supported, as this is a read-only collection.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TryGetValue	Gets the value associated with the specified key.

Extension Methods

	Name	Description
	ApplyTValue, TResult(FuncTValue, TResult)	Overloaded. Applies a function to every element of the array. (Defined by Matrix.)
	ApplyTValue, TResult(FuncTValue, TResult, TResult)	Overloaded. Applies a function to every element of the array. (Defined by Matrix.)
	HasMethod	Checks whether an object implements a method with the given name. (Defined by ExtensionMethods.)
	IsEqual	Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices. (Defined by Matrix.)
	SetEqualsKeyValuePairTKey, TValue(IEnumerableKeyValuePairTKey, TValue)	Overloaded. Compares two enumerables for set equality. Two enumerables are set equal if they contain the same elements, but not necessarily in the same order. (Defined by Matrix.)
	SetEqualsTValue(IEnumerableTValue)	Overloaded. (Defined by Matrix.)
	ShuffleTValue	Shuffles a collection. (Defined by Vector.)
	To(Type)	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
	ToT	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)

Remarks

This collection implements a read-only keyed collection. Read-only collections can not be changed once they are created and are useful for presenting information to the user without allowing alteration. A keyed collection is a collection whose elements can be retrieved by key or by index.
