找不到ASP.NET C＃404页面

Question

Can any one help me with the following error.

When I try to type my link like this localhost:1297/Index.aspx , it open properly.

But when I try to open the link like this

http://localhost:1297/Index.aspxabc

it throws 404 error .

I tried to handle this error by add a code in web.config as shown below :

<customErrors mode="On" defaultRedirect="~/Error.aspx">
      <error statusCode="404" redirect="~/404.aspx"/>
</customErrors>

But still it is showing the same error :

Answer 1

Try this i think it will solve the issue

 <configuration>

   <system.web>
      <customErrors mode="On" redirectMode="ResponseRewrite">
         <error statusCode="404" redirect="404.aspx" />
      </customErrors>
   </system.web>

   <system.webServer>
      <httpErrors errorMode="Custom">
         <remove statusCode="404"/>
         <error statusCode="404" path="/404.aspx" responseMode="ExecuteURL"/>
      </httpErrors>
   </system.webServer>

</configuration>
