Queryable.AsQueryable Method (IEnumerable)
Assembly: System.Core (in System.Core.dll)
If the type of source implements IQueryable<T>, returns it directly. Otherwise, it returns an IQueryable<T> that executes queries by calling the equivalent query operator methods in Enumerable instead of those in Queryable.
This method assumes that source implements IEnumerable<T> for some T. At runtime, the result is of type IQueryable<T> for the same T. This method is useful in dynamic scenarios when you do not statically know the type of T.
