SyntaxThe CollectionExtensions type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | AddRange(IList, IEnumerable) | Adds the elements of the specified collection to the end of the list. |
| AddRangeT(ICollectionT, IEnumerableT) | Adds the elements of the specified collection to the end of the list. |
| AddRangeT(ICollectionT, T, T, T) | Adds the elements of the specified collection to the end of the list. |
| ContainsAny(String, Char) | Shortcut to test if any of the given characters is contained in the specified string. |
| ContainsAnyT(IEnumerableT, T) | Shortcut to test if any of the given items are contained in the specified object. |
| ContainsAnyT(IEnumerableT, IEqualityComparerT, T) | Shortcut to test if any of the given items are contained in the specified object. |
| FindIndexT | Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the first occurrence within the entire IEnumerableT. |
| ForceValueTKey, TValue(IDictionaryTKey, TValue, TKey, TValue) | Gets the value associated with the specified key from the dictionary, or creates a new entry if the dictionary does not contain a value associated with the key. |
| ForceValueTKey, TValue(IDictionaryTKey, TValue, TKey, FuncTKey, TValue) | Gets the value associated with the specified key from the dictionary, or creates a new entry if the dictionary does not contain a value associated with the key. |
| ForEachT(IEnumerableT, ActionT, Int32) | Performs the specified action on each element of the collection, providing also the index of the item. |
| ForEachT(IEnumerableT, ActionT) | Performs the specified action on each element of the collection. |
| GetValueOrDefaultTKey, TValue(DictionaryTKey, TValue, TKey) | Gets the value from the dictionary, or the default value of TValue if no item with the specified key exists. |
| GetValueOrDefaultTKey, TValue(IDictionaryTKey, TValue, TKey) | Gets the value from the dictionary, or the default value of TValue if no item with the specified key exists. |
| GetValueOrDefaultTKey, TValue(IReadOnlyDictionaryTKey, TValue, TKey) | Gets the value from the dictionary, or the default value of TValue if no item with the specified key exists. |
| GetValueOrDefaultTKey, TValue(DictionaryTKey, TValue, TKey, TValue) | Gets the value from the dictionary, or the default value if no item with the specified key exists. |
| GetValueOrDefaultTKey, TValue(IDictionaryTKey, TValue, TKey, TValue) | Gets the value from the dictionary, or the default value if no item with the specified key exists. |
| GetValueOrDefaultTKey, TValue(IReadOnlyDictionaryTKey, TValue, TKey, TValue) | Gets the value from the dictionary, or the default value if no item with the specified key exists. |
| IndexOfT(IEnumerableT, T) | Searches for the specified object and returns the zero-based index of the first occurrence within all items. |
| IndexOfT(IEnumerableT, T, IEqualityComparerT) | Searches for the specified object and returns the zero-based index of the first occurrence within all items. |
| RemoveRange(IList, IEnumerable) | Removes a range of elements from the list. |
| RemoveRangeT(ICollectionT, IEnumerableT) | Removes a range of elements from the list. |
| RemoveWhereT | Removes the range of elements from the list that fulfill the condition. |
  | RepeatT | Repeats the specified source multiple times. |
| SynchronizeWithT(ICollectionT, ICollectionT) | Synchronizes the items of the source list with the items of the target list. The order of the items is ignored. |
| SynchronizeWithT(ICollectionT, ICollectionT, IEqualityComparerT) | Synchronizes the items of the source list with the items of the target list. The order of the items is ignored. |
| TakeT | Retrieves the specified number of items from the source. If source contains less items than specified, all available items are returned. |
| ToArrayTSource, TTarget | Creates an array from a ICollectionT. This method is faster than using Enumerable.Select(selector).ToArray() because the size of the target array is known in advance. |
| ToDictionaryTKey, TValue(IEnumerableKeyValuePairTKey, TValue) | Creates a Dictionary{TKey, TValue} from an IEnumerable{KeyValuePair{TKey, TValue}}. |
| ToDictionaryTKey, TValue(IEnumerableKeyValuePairTKey, TValue, IEqualityComparerTKey) | Creates a Dictionary{TKey, TValue} from an IEnumerable{KeyValuePair{TKey, TValue}}. |
| TransposeTKey, TValue | Transposes the specified items, i.e. exchanges key and value. |
| TryAddRangeT | Adds the elements of the specified collection to the end of the list, but ignores all ArgumentException, e.g. when trying to add duplicate keys to a dictionary. |
