Check if URL is a valid SPWeb in an SPSite

Question

I have a URL and I want to check if it exists as sub-site for a given URL.

• I have a URL = www.go.com
• I want to check if = www.go.com has URL = www.go.com/abx or not

I have +1000 sub webs, do I have to loop them all, no shortcut?

Answer 1

You can go with what Supermode and Unnie have suggested, you may also choose to use the below code as well:

using (SPSite site = new SPSite("http://www.go.com/"))    
{    
        using (SPWeb oWeb= site.OpenWeb())
        {
            SPWeb IsWebExists = oWeb.Webs.FirstOrDefault(x => x.Name == "abx");
            if (IsWebExists == null)
            {
                  //Your Code
            }
        }
}

Answer 2

Try below code:

using (SPSite site = new SPSite("http://www.go.com/"))
{
  using (SPWeb web = site.OpenWeb("abx"))
  {
     if (web.Exists)
         Console.WriteLine("exists");
     else
         Console.WriteLine("not exists");

  }
}

Just make sure inside site.OpenWeb, you provide the site relative url of the web

Answer 3

You can try the following

string serverUrl = "http://myserver";
string siteUrl = "/sites/SiteCollection";
string subSiteUrl = "This Subsite Does Not Exist";
using (SPSite site = new SPSite(serverUrl + siteUrl))
{
    using (SPWeb web = site.OpenWeb(subSiteUrl))
    {
        if (web.Exists)
        {
            // do work with the web...
            Console.WriteLine(site.Url);
            Console.WriteLine(web.Url);
        }
    }
}
