.NET 4.0: Is it possible to call ConvertAll for IList<>?

Question

'ConvertAll' is not implemented for IList, Am I right? Is there any workaround?

Answer 1

IList<T> does not define a method called ConvertAll(). You can see the definition here: http://msdn.microsoft.com/en-us/library/5y536ey6.aspx

There is a method on the concrete implementation List<T>; http://msdn.microsoft.com/en-us/library/73fe8cwf.aspx

You can replicate this behaviour using the LINQ statement .Select().
