Answer 1

.NET: Check URL's response status code?

First answer will return “url status”.
Then check the return status with if condition == “400” .. etc.

An example;

List< string > urls = new List< string >
urls.add("www.google.com");
urls.add("www.ggg.com");

foreach(var url in urls)
{
//cast string to HttpResponse will need here...
if( GetHeaders(url).ToString() == "400" )
MessageBox.Show(url + " status code is 400");
}

Something like that...
