Question

Can someone guide me on to repairing the error on this query :

       var objApps = from item in xDoc.Descendants("VHost") 
                          where(from x in item.Descendants("Application"))
                          select new clsApplication
                       {
                           ConnectionsTotal = item.Element("ConnectionsTotal").Value
                       };

It displays a compiler error “A query body must end with a select clause or a group clause”. Where am I going wrong?

Would appreciate any help..

Thanks.

Edit : Here is my XML(haven’t closed the tags here)…I need the connectioncount values inside the Application..

    - <Server>
  <ConnectionsCurrent>67</ConnectionsCurrent> 
  <ConnectionsTotal>1424182</ConnectionsTotal> 
  <ConnectionsTotalAccepted>1385091</ConnectionsTotalAccepted> 
  <ConnectionsTotalRejected>39091</ConnectionsTotalRejected> 
  <MessagesInBytesRate>410455.0</MessagesInBytesRate> 
  <MessagesOutBytesRate>540146.0</MessagesOutBytesRate> 
- <VHost>
  <Name>_defaultVHost_</Name> 
  <TimeRunning>5129615.178</TimeRunning> 
  <ConnectionsLimit>0</ConnectionsLimit> 
  <ConnectionsCurrent>67</ConnectionsCurrent> 
  <ConnectionsTotal>1424182</ConnectionsTotal> 
  <ConnectionsTotalAccepted>1385091</ConnectionsTotalAccepted> 
  <ConnectionsTotalRejected>39091</ConnectionsTotalRejected> 
  <MessagesInBytesRate>410455.0</MessagesInBytesRate> 
  <MessagesOutBytesRate>540146.0</MessagesOutBytesRate> 
- <Application>

Answer 1

The compiler is complaining about this part

from x in item.Descendants("Application")

inside your Where clause. You should change it so that

• there is a select clause at the end, and
• it makes up an expression that evaluates to true for item objects that you would like to keep.

Here is my best guess at what you are trying to do (EDIT : attempt number two)

var objApps = from item in xDoc.Descendants("VHost").Descendants("Application") 
              select new clsApplication {
                  ConnectionsTotal = item.Element("ConnectionsTotal").Value
              };
