Google Search API - Number of Results

问题

Whenever you perform a Google search, it spits out this little snippet of info

"About 8,110,000 results (0.10 seconds)"

I'm using the number of results certain terms return to rank them against each other, so if I could get this integer - 8,110,000 - via the API it would be very helpful. Some Google API's have recently been deprecated, so if you could point me to the right one that isn't deprecated, it would be very helpful.

Any other workarounds would also be much appreciated. I've seen one or two old posts on similar topics, but none seemed to be resolved successfully.

Completed using Bing instead of Google and with the following code:

string baseURL = "http://api.search.live.net/xml.aspx?Appid=<MyAppID>&query=%22" + name + "%22&sources=web";
WebClient c = new WebClient();
c.DownloadStringAsync(new Uri(baseURL));
c.DownloadStringCompleted += new DownloadStringCompletedEventHandler(findTotalResults);

and this calls findTotalResults:

void findTotalResults(object sender, DownloadStringCompletedEventArgs e)
{
    lock (this)
    {
        string s = e.Result;
        XmlReader reader = XmlReader.Create(new MemoryStream(System.Text.UTF8Encoding.UTF8.GetBytes(s)));
        while (reader.Read())
        {
            if (reader.NodeType == XmlNodeType.Element)
            {
                if (reader.Name.Equals("web:Total"))
                {
                    gResults = reader.ReadInnerXml();
                }

            }
        }
    }
}
