Remarks
Enumerating the collection in C#
A TriggerCollection is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable<EventTrigger> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable with an EventTrigger constraint.

Removes all items from the collection. |
| First() |
Returns the iterator for iteration over the items in the collection. |
| GetAt(UInt32) |
Returns the item located at the specified index. |
| GetMany(UInt32, TriggerBase[]) |
Retrieves multiple elements in a single pass through the iterator. |
| GetView() |
Gets an immutable view into the collection. |
| IndexOf(TriggerBase, UInt32) |
Retrieves the index of the specified item. |
| InsertAt(UInt32, TriggerBase) |
Inserts the specified item at the specified index. |
| RemoveAt(UInt32) |
Removes the item at the specified index. |
| RemoveAtEnd() |
Removes the last item in the collection. |
| ReplaceAll(TriggerBase[]) |
Initially clears the collection, then inserts the provided array as new items. |
| SetAt(UInt32, TriggerBase) |
Sets the value at the specified index to the TriggerBase value specified. |
