Adding parameters to an Uri is an example where my NameValueCollectionHelper comes in handy. Although UriTemplate allows us to bind parameters, it doesn’t really support add/remove/fail on duplicate parameters. Here is an example:

[TestMethod]
public void TestAddParametersReplaceWithReplaceOfExistingParameters()
{
 Uri originalUri = new Uri("http://www.example.com/path/?key1=val1&key2=val2#abcd")

 NameValueCollection parameters = new NameValueCollection();
 parameters.Add("key1", "newval");
 parameters.Add("key3", "val3");

 Uri expected = new Uri("http://www.example.com/path/?key1=newval&key2=val2&key3=val3#abcd");

 Uri actual = UriHelper.AddParameters(originalUri, parameters, DuplicateKeyBehavior.Replace);
 Assert.AreEqual(expected, actual);
}
