Represents a strongly typed list of objects that can be accessed by index. Provides methods to search, sort, and manipulate lists. Represents a collection of items that have a value and a priority. On dequeue, the item with the lowest priority value is removed. Represents a variable size last-in-first-out LIFO collection of instances of the same specified type. Provides a thread-safe collection that contains objects of a type specified by the generic parameter as elements.
Provides a thread-safe collection that contains objects of a type specified by a generic parameter and that are grouped by keys. Provides a thread-safe, read-only collection that contains objects of a type specified by the generic parameter as elements.
Many of the generic collection types are direct analogs of nongeneric types. Both versions are hybrids of a dictionary and a list. Enumerates and transforms a sequence, and produces an immutable sorted dictionary of its contents by using the specified key and value comparers.

Casts the elements of an IEnumerable to the specified type. Splits the elements of a sequence into chunks of size at most size. Determines whether a sequence contains a specified element by using the default equality comparer. Returns a number that represents how many elements in the specified sequence satisfy a condition.
Returns the elements of the specified sequence or the type parameter's default value in a singleton collection if the sequence is empty. Returns the elements of the specified sequence or the specified value in a singleton collection if the sequence is empty. Returns distinct elements from a sequence by using the default equality comparer to compare values. Returns distinct elements from a sequence according to a specified key selector function and using a specified comparer to compare keys.
Returns the element at a specified index in a sequence or a default value if the index is out of range. Produces the set difference of two sequences by using the default equality comparer to compare values.
Returns the first element of a sequence, or a default value if the sequence contains no elements. Returns the first element of a sequence, or a specified default value if the sequence contains no elements. Returns the first element of the sequence that satisfies a condition or a default value if no such element is found.
Returns the first element of the sequence that satisfies a condition, or a specified default value if no such element is found. Groups the elements of a sequence according to a specified key selector function and compares the keys by using a specified comparer.
Groups the elements of a sequence according to a specified key selector function and projects the elements for each group by using a specified function. Groups the elements of a sequence according to a key selector function. The keys are compared by using a comparer and each group's elements are projected by using a specified function. Groups the elements of a sequence according to a specified key selector function and creates a result value from each group and its key.
The keys are compared by using a specified comparer. The elements of each group are projected by using a specified function. Key values are compared by using a specified comparer, and the elements of each group are projected by using a specified function. Correlates the elements of two sequences based on equality of keys and groups the results.
The default equality comparer is used to compare keys. Correlates the elements of two sequences based on key equality and groups the results. Produces the set intersection of two sequences by using the default equality comparer to compare values. Correlates the elements of two sequences based on matching keys. Returns the last element of a sequence, or a specified default value if the sequence contains no elements.
Returns the last element of a sequence that satisfies a condition or a default value if no such element is found. Returns the last element of a sequence that satisfies a condition, or a specified default value if no such element is found. Returns an Int64 that represents the total number of elements in a sequence. Returns an Int64 that represents how many elements in a sequence satisfy a condition.
