If you've worked with ASP.NET before then you've almost certainly seen an application-relative URL like ~/SomeFolder/SomePage.aspx. The tilde at the beginning is a stand in for the application path, and it can easily be resolved using the Page object's ResolveUrl method:
string url = Page.ResolveUrl("~/SomeFolder/SomePage.aspx");
There are times, however, when you don't have a page object available and you need to resolve an application relative URL. Assuming you have an HttpContext object available, the following method will accomplish just that:
public static string ResolveAppRelativeUrl(string url)
{
return url.Replace("~", System.Web.HttpContext.Current.Request.ApplicationPath);
}
