Extension Methods

	Name	Description
	AddRangeKeyValuePairTKey, TValue	Adds a range of items to a collection. (Defined by ListExtensions)
	FillWithKeyValuePairTKey, TValue	(Defined by ListExtensions)
	FirstOrKeyValuePairTKey, TValue	Returns the first value of the enumeration, or, if the enumeration is empty, the other value provided in the arguments. (Defined by EnumerableExtensions)
	FlattenFromRootToLeavesKeyValuePairTKey, TValue	Converts a recursive data structure into a flat list. The root element is enumerated before its corresponding child element(s). (Defined by EnumerableExtensions)
	ForEachDoKeyValuePairTKey, TValue	Executes an action for each element of the sequence. (Defined by EnumerableExtensions)
	HasSingleElementKeyValuePairTKey, TValue	Determines whether the specified enumeration has exactly one element. (Defined by EnumerableExtensions)
	IndexOfKeyValuePairTKey, TValue	Gets the index of an item in a enumeration or list. (Defined by ListExtensions)
	IndexOfFirstKeyValuePairTKey, TValue	Gets the index the of first item in list that fulfills the predicate predicate (Defined by ListExtensions)
	IndexOfFirstKeyValuePairTKey, TValue	Gets the index the of first item in list that fulfills the predicate predicate (Defined by ListExtensions)
	IndexOfMaxKeyValuePairTKey, TValue	Return the index of the element with the maximum value in an enumerable. If multiple elements with the same minimal value exist, the index of the first element in the sequence is returned. (Defined by EnumerableExtensions)
	IndexOfMinKeyValuePairTKey, TValue	Return the index of the element with the minimum value in an enumerable. If multiple elements with the same minimal value exist, the index of the first element in the sequence is returned. (Defined by EnumerableExtensions)
	IndicesInt32AndValuesWhereKeyValuePairTKey, TValue	Returns tuples of index and element of all elements in an enumeration which fullfill a given condition, given by the element's value. (Defined by EnumerableExtensions)
	IndicesInt32AndValuesWhereKeyValuePairTKey, TValue	Returns tuples of index and element of all elements in an enumeration which fullfill a given condition, given by the element's value and its index. (Defined by EnumerableExtensions)
	IndicesInt32WhereKeyValuePairTKey, TValue	Returns the indices of the elements which fullfill a given condition, given by the element's value. (Defined by EnumerableExtensions)
	IndicesInt32WhereKeyValuePairTKey, TValue	Returns the indices of the elements which fullfill a given condition, given by the element's value and its index. (Defined by EnumerableExtensions)
	IndicesOfMinMaxKeyValuePairTKey, TValue	Return the index of the element with the minimum value in an enumerable. If multiple elements with the same minimal value exist, the index of the first element in the sequence is returned. (Defined by EnumerableExtensions)
	IsEmptyKeyValuePairTKey, TValue	Determines whether the specified enumeration is empty. (Defined by EnumerableExtensions)
	JoinConditionalKeyValuePairTKey, TValue, T2	Takes a join of two sequences, but only takes into account those pair, which fulfill a given condition. (Defined by EnumerableExtensions)
	JoinConditionalKeyValuePairTKey, TValue, T2, TResult	Takes a join of two sequences, but only takes into account those pair, which fulfill a given condition. (Defined by EnumerableExtensions)
	LastOrKeyValuePairTKey, TValue	Returns the last value of the enumeration, or, if the enumeration is empty, the other value provided in the arguments. (Defined by EnumerableExtensions)
	MaxElementKeyValuePairTKey, TValue, M	Gets the element of a IEnumerabe that evaluates by means of a conversion function to the maximal value. This is different from Select(x => conversion(x)).Max() insofar as it not returns the maximum value, but the original element x which converts to the maximum value. (Defined by EnumerableExtensions)
	MaxOrDefaultKeyValuePairTKey, TValue, M	Evaluates the maximum of a enumeration of elements, or returns a default value if the series is empty. (Defined by EnumerableExtensions)
	SelectCombinationKeyValuePairTKey, TValue	Select a random combination, without repetition, from a data sequence by selecting k elements in original order. (Defined by Combinatorics)
	SelectCombinationWithRepetitionKeyValuePairTKey, TValue	Select a random combination, with repetition, from a data sequence by selecting k elements in original order. (Defined by Combinatorics)
	SelectPermutationKeyValuePairTKey, TValue	Select a random permutation from a data sequence by returning the provided data in random order. Implemented using Fisher-Yates Shuffling. (Defined by Combinatorics)
	SelectVariationKeyValuePairTKey, TValue	Select a random variation, without repetition, from a data sequence by randomly selecting k elements in random order. Implemented using partial Fisher-Yates Shuffling. (Defined by Combinatorics)
	SelectVariationWithRepetitionKeyValuePairTKey, TValue	Select a random variation, with repetition, from a data sequence by randomly selecting k elements in random order. (Defined by Combinatorics)
	TakeAllButLastKeyValuePairTKey, TValue	Takes all elements of the enumeration except the last element. (Defined by EnumerableExtensions)
	ThisOrEmptyKeyValuePairTKey, TValue	Returns either the provided enumeration, or if it is null, an empty enumeration. (Defined by EnumerableExtensions)
	TryGetFirstAndLastKeyValuePairTKey, TValue	Returns true and the first and last value of the enumeration, or, if the enumeration is empty, returns false. (Defined by EnumerableExtensions)
	TryGetSingleElementKeyValuePairTKey, TValue	Try to get the one and only element of the collection. (Defined by EnumerableExtensions)
