: 나는 오류에 대한 몇 가지 연구를 위해 노력했다

for (var i = 0; i< 5000; i++) 
    var page = web.Load(url+Convert.ToString(i+1)+"/"); 

, 그러나 밖에서 형성에 많은 것이 없었다.

Answer 1

1000+ 개 웹 페이지를 다운로드 한 후에도 동일한 오류가 발생했습니다. 루프에서 IOException과 관련된 추가 캐치로 해결했습니다. 내 코드는 다음과 같습니다.

HtmlWeb web = new HtmlWeb(); 
web.PreRequest = delegate(HttpWebRequest webRequest) 
{ 
    webRequest.Timeout = 15000; 
    return true; 
}; 

try { doc = web.Load(yUrl); } 
catch (WebException ex) 
{ 
    reTryCounter++; 
    if (reTryCounter == 19) { MessageBox.Show("Error Program 1121 , Download webpage \n" + ex.ToString()); } 
} 
catch (IOException ex2) 
{ 
    MessageBox.Show("Error Program 1125 , IOException Download webpage \n" + ex2.ToString()); 
    return null; 
}
