Gets a collection of query string values.
Assembly: Microsoft.Phone (in Microsoft.Phone.dll)
You retrieve values from the query string to generate the desired state of a page for a navigation request. A navigation request with query string values includes the query string key/value pairs after a question mark (?) delimiter. For example, you can store in the query string the identifier of the record you wish to display on a page, such as /Views/Product.xaml?productid=45&format=long. The values from the query string are decoded before being stored in the collection.
