HttpValueCollection and NameValueCollection

What is the difference between


If possible please explain with example.


Answer Source

NameValueCollection is case sensitive for the keys, HttpValueCollection isn't. Also HttpValueCollection is an internal class that derives from NameValueCollection that you are never supposed to use directly in your code. Another property of HttpValueCollection is that it automatically url encodes values when you add them to this collection.

Here's how to use the HttpValueCollection class:

class Program
    static void Main()
        // returns an implementation of NameValueCollection
        // which in fact is HttpValueCollection
        var values = HttpUtility.ParseQueryString(string.Empty);
        values["param1"] = "v&=+alue1";
        values["param2"] = "value2";*

        // prints "param1=v%26%3d%2balue1&param2=value2"
