I have to refactor some sharepoint 2010 code from my collegue. Everytime he needs to access a list he does this:
SPContext.Current.Web.Site.OpenWeb().Lists["List"];
I used to do this:
SPContext.Current.Web.Lists["List"];
What’s the difference between these two and whats the more efficient way?
The second is much more efficient way.
In the first method, you are creating a new
SPWebobject through theOpenWeb()call which is an expensive call. Note only that, you must also explicitly dispose this object manually when you are done using that.Read here:
