List<(Of <(T>)>) Members

Represents a strongly typed list of objects that can be accessed by index. Provides methods to search, sort, and manipulate lists.

The List<(Of <(T>)>) type exposes the following members.

Constructors

	Name	Description
	List<(Of <(T>)>)	Overloaded. Initializes a new instance of the List<(Of <(T>)>) class.

	AddRange	Adds the elements of the specified collection to the end of the List<(Of <(T>)>).
	AsReadOnly	Returns a read-only IList<(Of <(T>)>) wrapper for the current collection.
	BinarySearch	Overloaded. Uses a binary search algorithm to locate a specific element in the sorted List<(Of <(T>)>) or a portion of it.

	Contains	Determines whether an element is in the List<(Of <(T>)>).

	CopyTo	Overloaded. Copies the List<(Of <(T>)>) or a portion of it to an array.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Exists	Determines whether the List<(Of <(T>)>) contains elements that match the conditions defined by the specified predicate.
	Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	Find	Searches for an element that matches the conditions defined by the specified predicate, and returns the first occurrence within the entire List<(Of <(T>)>).
	FindAll	Retrieves all the elements that match the conditions defined by the specified predicate.
	FindIndex	Overloaded. Searches for an element that matches the conditions defined by a specified predicate, and returns the zero-based index of the first occurrence within the List<(Of <(T>)>) or a portion of it.
	FindLast	Searches for an element that matches the conditions defined by the specified predicate, and returns the last occurrence within the entire List<(Of <(T>)>).
	FindLastIndex	Overloaded. Searches for an element that matches the conditions defined by a specified predicate, and returns the zero-based index of the last occurrence within the List<(Of <(T>)>) or a portion of it.
	ForEach	Performs the specified action on each element of the List<(Of <(T>)>).
	GetEnumerator	Returns an enumerator that iterates through the List<(Of <(T>)>).
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetRange	Creates a shallow copy of a range of elements in the source List<(Of <(T>)>).
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IndexOf	Overloaded. Returns the zero-based index of the first occurrence of a value in the List<(Of <(T>)>) or in a portion of it.
	Insert	Inserts an element into the List<(Of <(T>)>) at the specified index.
	InsertRange	Inserts the elements of a collection into the List<(Of <(T>)>) at the specified index.
	LastIndexOf	Overloaded. Returns the zero-based index of the last occurrence of a value in the List<(Of <(T>)>) or in a portion of it.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Remove	Removes the first occurrence of a specific object from the List<(Of <(T>)>).
	RemoveAll	Removes the all the elements that match the conditions defined by the specified predicate.
	RemoveAt	Removes the element at the specified index of the List<(Of <(T>)>).
	RemoveRange	Removes a range of elements from the List<(Of <(T>)>).
	Reverse	Overloaded. Reverses the order of the elements in the List<(Of <(T>)>) or a portion of it.
	Sort	Overloaded. Sorts the elements in the List<(Of <(T>)>) or a portion of it.
	ToArray	Copies the elements of the List<(Of <(T>)>) to a new array.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)
	TrimExcess	Sets the capacity to the actual number of elements in the List<(Of <(T>)>), if that number is less than a threshold value.
	TrueForAll	Determines whether every element in the List<(Of <(T>)>) matches the conditions defined by the specified predicate.
