Implements
IList.Insert(Int32, Object)| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | index is less than zero. -or- index is greater than Count. |
| NotSupportedException | The StringCollection is read-only. -or- The StringCollection has a fixed size. |
If Count already equals the capacity, the capacity of the StringCollection is increased by automatically reallocating the internal array, and the existing elements are copied to the new array before the new element is added.
If index is equal to Count, value is added to the end of StringCollection.
In collections of contiguous elements, such as lists, the elements that follow the insertion point move down to accommodate the new element. If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does not apply to collections where elements are conceptually grouped into buckets, such as a hash table.
This method is an O(n) operation, where n is Count.
