SPContext.Current vs SPContext.GetContext

Question

To get current SP objects (SPWeb, SPSite, SPList etc), I generally use SPContext.Current. In some situations, SPContext.GetContext is preferred because SPContext.Current have many objects null depending on where the code runs (Webpart page, Edit item form etc).

Are you aware of any guidelines (may be from Microsoft) on the usage SPContext.Current and SPContext.GetContext ?

Answer 1

Another reason for using the SPContext.GetContext is to set the context of a control to one that is different than the context of the current page. For example, you can set the ItemFieldIterator.ItemContext proprty to get information from a list on different SPWeb object.

myItemFieldIterator.ItemContext = SPContext.GetContext(Context, 0, ListId, oSPWeb);

Answer 2

SPContext.GetContext tends to be used if there is no current context (console app? timer job? FeatureUninstalling?), whereby in the case where you do, you would use the obviously named SPContext.Current.
