StringCollection class is a new addition to the .NET Framework class library that represents a collection of strings. StringCollection class is defined in the System.Collections.Specialized namespace.
StringCollection.Insert(Int32, String) method is used to insert a string into the StringCollection at the specified index.
public void Insert (int index, string value);
- index: The zero-based index at which value is inserted.
- value: The string to insert. The value can be null.
Exception: This method will give ArgumentOutOfRangeException if the index is less than zero Or index is greater than Count.
- Duplicate strings are allowed in StringCollection.
- If index is equal to Count, value is added to the end of StringCollection.
- This method is an O(n) operation, where n is Count.
