UriTemplateEquivalenceComparer Class

// Define two structurally equivalent templates
UriTemplate temp1 = new UriTemplate("weather/{state}/{city}");
UriTemplate temp2 = new UriTemplate("weather/{country}/{village}");

// Notice they are not reference equal, in other words
// they are do not refer to the same object
if (temp1 == temp2)
    Console.WriteLine("{0} and {1} are reference equal", temp1, temp2);
else
    Console.WriteLine("{0} and {1} are NOT reference equal", temp1, temp2);

// Notice they are structrually equal
if (temp1.IsEquivalentTo(temp2))
    Console.WriteLine("{0} and {1} are structurally equal", temp1, temp2);
else
    Console.WriteLine("{0} and {1} are NOT structurally equal", temp1, temp2);

// Create a dictionary and use UriTemplateEquivalenceComparer as the comparer
Dictionary<UriTemplate, object> templates = new Dictionary<UriTemplate, object>(new UriTemplateEquivalenceComparer());

// Add template 1 into the dictionary
templates.Add(temp1, "template1");

// The UriTemplateEquivalenceComparer will be used here to compare the template in the table with template2
// they are structurally equivalent, so ContainsKey will return true.
if (templates.ContainsKey(temp2))
    Console.WriteLine("Both templates hash to the same value");
else
    Console.WriteLine("Both templates do NOT hash to the same value");
