Re: Relative URI parsing

Yuan

Ah, it's implementing an earlier version of the RFC for URI than I was
expecting; the latest is 3986, but as I was only published in Jan 2005 I can
see why Net 1.1 wouldn't have it :-) The differences are mainly that the
authority component is optional, and that a relative reference can't
abstract away the authority component only the path, hence the differences
in the test results.

The context of this is developing a library for Topic Maps (which uses URI's
as the identifiers of the referenced topics) so I wanted to make sure that
any URI I found in a topic map was going to be parsed correctly.

The examples I posted are the normative tests from the RFC I mentioned; the
code itself is trivial...

Uri baseUri = new Uri("http://a/b/c/d;p?q";);
for (int i = 0; i < tests.GetUpperBound(0); i++)
{
Uri relUri = new Uri(baseUri, tests[i][0]);
Assert.AreEqual(tests[i][1], loc.Scheme, "Mismatched scheme for " +
tests[i][0]);
Assert.AreEqual(tests[i][2], loc.Authority, "Mismatched authority for "
+ tests[i][0]);
Assert.AreEqual(tests[i][3], loc.PathString, "Mismatched path for " +
tests[i][0]);
Assert.AreEqual(tests[i][4], loc.Query, "Mismatched query for " +
tests[i][0]);
Assert.AreEqual(tests[i][5], loc.Fragment, "Mismatched fragment for " +
tests[i][0]);
}

I'll just have to develop my own Uri class for the time being.
