At the moment I am trying to make a web crawler and I am stuck with this error:

Exception thrown: 'System.Net.WebException' in System.dll

Additional information: The remote server returned an error: (405) Method Not Allowed.

Here is my code:

Stream receiveStream = null;
url = item1;
HttpWebRequest request1 = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response1 = (HttpWebResponse)request1.GetResponse();
receiveStream = response1.GetResponseStream();
StreamReader readStream = null;
if (response.CharacterSet == null)
{
    readStream = new StreamReader(receiveStream);
}
else
{
    readStream = new StreamReader(receiveStream, Encoding.GetEncoding(response.CharacterSet));
}

html = readStream.ReadToEnd();

response1.Close();
readStream.Close();

How can I skip to the next "item1" if I get this error?

You don't need to skip anything. Can you give us an example of item1? – Aakash Verma Jul 04 '17 at 08:49
item1=https://example.com – Nitescu Lucian Jul 04 '17 at 08:49
if you don't care anymore as soon as you receive a 501, why not just wrap it in a try/catch? – Timothy Groote Jul 04 '17 at 08:49
item1=http://emaple.com/1.js – Nitescu Lucian Jul 04 '17 at 08:50
The Default HttpWebRequest is "Get" and I believe the API you are trying to call does not accept GET. Try with POST – Sujith Jul 04 '17 at 08:50
Yes, that's the problem I guess. The URL requires POST request and not GET or HEAD which you'd be sending. – Aakash Verma Jul 04 '17 at 08:50
@Sujith can I have both GET and POST at the same time? – Nitescu Lucian Jul 04 '17 at 08:50
@Sujith by that logic, PUT and DELETE should also be probed. that makes no sense for a crawler – Timothy Groote Jul 04 '17 at 08:51
No, only one. You cannot have a request of both types. – Aakash Verma Jul 04 '17 at 08:51

can you guys show me a a try {} catch {} in order to switch to post or head? – Nitescu Lucian Jul 04 '17 at 08:52
