Now i want to retrieve only Domain name i.e amazon out of these urls.Can any one did this before??

Thanks,

Try this:

using System;

class Test

{

static void Main()

{

string[] urls =

{

@"http://g-ecx.images-amazon.com",

@"http://z-ecx.images-amazon.com",

@"http://ecx.images-amazon.com",

@"http://completion.amazon.com",

@"http://client-log.amazon.com",

@"http://www.amazon.com/184-8984226-0489751",

@"http://www.amazon.com/access",

@"http://www.amazon.com/gp/product/B0083PWAPW/ref=kin_dev_gw_dual_t/184-898422604...",

@"http://www.amazon.com/gp/product/B007OZNZG0/ref=kin_dev_gw_dual_c/184-8984226-04...",

@"http://www.amazon.com/gp/prime/signup/videos/ref=nav_menu_video_redirect_combine...",

@"http://www.amazon.com/gp/prime/signup/videos/ref=nav_menu_video_pic_redirect_com...",

@"http://www.amazon.com/gp/prime/signup/videos/ref=nav_menu_shipping_redirect_comb...",

@"http://www.amazon.com/gp/prime/signup/videos/ref=nav_menu_shipping_pic_redirect_..."

};

foreach(string url in urls)

{

Uri uri = new Uri(url);

string[] items = uri.Host.Split('.');

string domain = "";

if (items.Length == 3)

{

domain = items[1];

}

else if (items.Length == 2)

{

domain = items[0];

}

if (domain.IndexOf('-') > -1)

{

domain = domain.Substring(domain.LastIndexOf('-') + 1);

}

Console.WriteLine(domain);

}

Console.ReadKey();

}
