Extension Methods| Name | Description | |
|---|---|---|
 | AddRangeKeyValuePairTKey, TValue |
Adds a range of items to a collection.
(Defined by ListExtensions) |
| FillWithKeyValuePairTKey, TValue |
Clears and fills a collection with the specified items.
(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) |
| GetSameOrDefaultKeyValuePairTKey, TValue, S |
Gets the same element if all elements of the enumeration (after a transformation) are the same. If the elements in the enumeration are different, the return value is null or default.
(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 an enumeration or list.
(Defined by ListExtensions) |
| IndexOfFirstKeyValuePairTKey, TValue |
Gets the index of the first item in list that fulfills the predicate predicate.
(Defined by ListExtensions) |
| IndexOfFirstKeyValuePairTKey, TValue |
Gets the index of the 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) |

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) |
