Full path URL for images for ASP.NET

C# SOLUTION
imgLogo.Src = System.Web.HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) + System.Web.HttpContext.Current.Request.ApplicationPath + "/images/logo.png";

How do I turn a relative URL into a full URL?

public string ConvertRelativeUrlToAbsoluteUrl(string relativeUrl)
{

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

}
