allowed domains/subdomains in Uri

Question

I have some url in Uri. How can i check if this url is part of some domain or subdomain.

Example:

URL:

http://www.example.com/something/index.apsx?lala=ddsadasd&dasdas=dsdas&dsdsd=ikpi&das=asd

allowed:

http://www.example.com/something/

not aloowed:

http://www.example.com/some/

if URL is in allowed domain then code continue executing.

Answer 1

Uri uri = new Uri("http://www.example.com/folder/page.ext?foo=bar");
uri.Segments.Contains("folder"); // true
uri.DnsSafeHost.Split('.').Contains("example"); // true

uri.Segements are:

• "/"
• "something/"
• "index.ext"

and DnsSafeHost.Split('.') are:

• www
• example
• com so you can manipulate with this data as you want.

Edit:

uri.Segments.Any(s => String.Equals(s.Replace("/", String.Empty), "something", StringComparison.OrdinalIgnoreCase));
uri.DnsSafeHost.Split('.').Any(s => String.Equals(s, "example", StringComparison.OrdinalIgnoreCase));
