Console.WriteLine("Matching {0} to {1}", template.ToString(), fullUri.ToString());

// Match a URI to a template
UriTemplateMatch results = template.Match(baseAddress, fullUri);
if (results != null)
{
    Console.WriteLine("QueryParameters:");
    foreach (string queryName in results.QueryParameters.Keys)
    {
        Console.WriteLine("    {0} : {1}", queryName, results.QueryParameters[queryName]);
    }
    Console.WriteLine();
}
// Code output:
//  QueryParameters:
//  forecast : today

Dim template As New UriTemplate("weather/ state}/ city}?forecast=today")
Dim baseAddress As New Uri("http://localhost")
Dim fullUri As New Uri("http://localhost/weather/WA/Seattle?forecast=today")

Console.WriteLine("Matching  0} to  1}", template.ToString(), fullUri.ToString())

'Match a URI to a template
Dim results As UriTemplateMatch = template.Match(baseAddress, fullUri)
If (results IsNot Nothing) Then

    Console.WriteLine("QueryParameters:")
    For Each queryName As String In results.QueryParameters.Keys
        Console.WriteLine("     0} :  1}", queryName, results.QueryParameters(queryName))
    Next
    Console.WriteLine()
End If
'Code output:
' QueryParameters:
' forecast : today

All query string name/value pairs from the original URI appear in this collection, even if they are not explicitly specified in the template string that was matched. The values in this collection have been had all escape sequences translated into actual characters.
