public:
void Insert(int index, T item);public void Insert (int index, T item);abstract member Insert : int * 'T -> unitPublic Sub Insert (index As Integer, item As T)Parameters
- index
- Int32
The zero-based index at which item should be inserted.
- item
- T
The object to insert into the IList<T>.
Exceptions
index is not a valid index in the IList<T>.
The IList<T> is read-only.
Remarks
If index equals the number of items in the IList<T>, then item is appended to the list.
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.
