UrlCombine Build Status

The UrlCombine is a Nuget Package to conveniently combine your base Url and relative url. This library treats the slashes between the base and relative paths to ensure a valid url.

  using UrlCombineLib;

There are 3 ways to use the library:

Static Method

The static method is used with UrlCombine helper class. It doesn't matter if the baseUrl and relativePath end/start with a slash or not, The Combine() method takes care of that:

  var fullUrl = UrlCombine.Combine("www.foo.com.br/", "/bar/zeta");
  // fullUrl = "www.foo.com.br/bar/zeta"

String Extension

The string extesion is used with the CombineUrl method:

  var fullUrl = "www.foo.com.br/".CombineUrl("/bar/zeta");
  // fullUrl = "www.foo.com.br/bar/zeta"

Uri Extension

The Uri extension is used with the Combine method:

  var fullUrl = new Uri("www.foo.com.br/").Combine("/bar/zeta");
  // fullUrl = new Uri("www.foo.com.br/bar/zeta")

Multiple relative paths in runtime

There's also a UrlCombine.Combine overload (alongside Uri and String extension methods) that takes a param string[] as input:

  var fullUrl = new Uri("www.foo.com.br/").Combine("bar", "zeta");
  // fullUrl = new Uri("www.foo.com.br/bar/zeta")

Why not Uri(Uri base, string relative)?

Well, It does more than just validate the slashes. It strips the relative path of the base Uri if it doesn't end with a slash and if the relative path doesn't start with one:

  var uriBase = new Uri("http://www.foo.com/relative");
  var relative = "/other/url";
  
  var uri = new Uri(uriBase, relative);
  // uri.ToString() = "http://www.foo.com/other/url"
