I feel kind of dumb posting this when this seems kind of simple and there are tons of questions on strings/characters/regex, but I couldn't find quite what I needed (except in another language: http://stackoverflow.com/questions/2176544/remove-all-text-after-certain-point).

I've got the following code:

[Test]
    public void stringManipulation()
    {
        String filename = "testpage.aspx";
        String currentFullUrl = "http://localhost:2000/somefolder/myrep/test.aspx?q=qvalue";
        String fullUrlWithoutQueryString = currentFullUrl.Replace("?.*", "");
        String urlWithoutPageName = fullUrlWithoutQueryString.Remove(fullUrlWithoutQueryString.Length - filename.Length);

        String expected = "http://localhost:2000/somefolder/myrep/";
        String actual = urlWithoutPageName;
        Assert.AreEqual(expected, actual);
    }

I tried the solution in the question above (hoping the syntax would be the same!) but nope. I want to first remove the queryString which could be any variable length, then remove the page name, which again could be any length.

How can I get the remove the query string from the full URL such that this test passes?
