NameValueCollection

Synopsis

This class is a collection of keys and associated values composed of strings in which a single key may have multiple values associated with it. A multivalued entry is stored as a comma-separated list of the string values. Use the Add() method to append new values to existing values of a key. Using Set() or setting the value by key name overwrites the existing value. You can use a string containing a comma-separated list to assign multiple values to a key.

The GetValues() method returns a string array containing all the values of the specified key (or index). An example of how this class is used is System.Net.WebHeaderCollection, which derives from it. A WebHeaderCollection contains the collection of various HTTP header names as key strings and their values. HTTP headers such as Accept: often have multiple values (for example, MIME types for Accept).
