如何打开一个相对URL为完整的URL？ [英] How do I turn a relative URL into a full URL?

问题描述

这是可能与一个例子来解释更容易。我试图找到转向相对URL的方式，例如， /Foo.aspx或〜/ Foo.aspx成一个完整的URL，例如 HTTP：//localhost/Foo.aspx 。当我部署的方式来测试或阶段，在该网站下运行的域是不同的，我会得到的http：//test/Foo.aspx 和 HTTP：//stage/Foo.aspx

This is probably explained more easily with an example. I'm trying to find a way of turning a relative URL, e.g. "/Foo.aspx" or "~/Foo.aspx" into a full URL, e.g. http://localhost/Foo.aspx. That way when I deploy to test or stage, where the domain under which the site runs is different, I will get http://test/Foo.aspx and http://stage/Foo.aspx.

任何想法？

public string ConvertRelativeUrlToAbsoluteUrl(string relativeUrl) {
    return string.Format("http{0}://{1}{2}",
        (Request.IsSecureConnection) ? "s" : "", 
        Request.Url.Host,
        Page.ResolveUrl(relativeUrl)
    );
}
