linq-to-xml

问题 I'm trying to construct a linq query that pulls all nodes that have a particular element. In the case below, you'll notice that the second entry has a few extra elements: DisplayOnSignup, SortOrder, etc. I'd like the linq to give me all entry nodes that have a SortOrder element. The xml doc looks like this: <?xml version="1.0" encoding="UTF-8"?> <feed > <entry> <link href="/ws/customers/testacct/lists/removed" rel="edit"></link> <id>http://api.constantcontact.com/ws/customers/testacct/lists

问题 I am trying to load data from XML string into a structure of some sort so once loaded I can then say Data.PropertyName to read the values. Is the below code the most optimal way of loading the data into the structure? Obviously calling First() has a memory hit so if you have elements with sub elements will calling First() for each one become an issue? Thanks string xml = @"<ROOT> <ID>1</ID> <NAME>RF1</NAME> <STAT>10200</STAT> <TEST> <ID>1</ID> <NAME>BIGUN</NAME> </TEST> </ROOT> "; XElement

问题 I have been playing around with linking XML files to dropdown lists and gridviews.
