本文介绍了一种处理HTTP请求中404错误的方法，通过捕获WebException并检查HttpWebResponse的状态码来判断是否为404错误，并提供相应的处理逻辑。

Hi, How to let Httpwebresponse ignore the 404 error and continue with it? It's easier than looking for exceptions in input as it is very rare when this happens.

try


    
{


        
HttpWebRequest
 request 
=
 
(
HttpWebRequest
)
HttpWebRequest
.
Create
(
"http://mysite.com"
);


        
HttpWebResponse
 response 
=
 
(
HttpWebResponse
)
request
.
GetResponse
();
          

    
}


    
catch
(
WebException
 ex
)


    
{


        
HttpWebResponse
 webResponse 
=
 
(
HttpWebResponse
)
ex
.
Response
;
          

        
if
 
(
webResponse
.
StatusCode
 
==
 
HttpStatusCode
.
NotFound
)


        
{


            
//Handle 404 Error...


        
}


    
}
