Convert Predicate<T> to Expression<Func<T, bool>>

Question

Is possible to convert a Predicate<T> to Expression<Func<T, bool>> in some way?

I would like to use the next IQueryable function using the filters of the my ICollectionView:

public static System.Linq.IQueryable<TSource> Where<TSource>(this System.Linq.IQueryable<TSource> source, System.Linq.Expressions.Expression<System.Func<TSource, bool>> predicate)

Thanks

In theory it is possible to convert a delegate 'back' to an expression, because you can request the emitted IL of a delegate, which gives you the information you need to transform it back.

However, it's for a reason that neither LINQ to SQL and Entity Framework do this. It is complex, fragile, and performance intensive to do so.

So the short answer is, you can't transform it to an expression.
