StringCollection.Insert Method (Int32, String)


Inserts a string into the StringCollection at the specified index.

Namespace:   System.Collections.Specialized
Assembly:  System (in System.dll)

member Insert : 
        index:int *
        value:string -> unit


Type: System.Int32

The zero-based index at which value is inserted.

Type: System.String

The string to insert. The value can be null.

Exception Condition

index is less than zero.


index greater than Count.

Duplicate strings are allowed in StringCollection.

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.

The following code example adds new elements to the StringCollection.
