Dynamically query an object set in EF using LambdaExpression

I am trying to dynamically query Entity Framework, so I'm using the Expression class to put together a LambdaExpression that will be queried against an object set. If I have a reference to LambdaExpression, where I don't have an explicit function defined, is it possible to query against an objectset this way, or is it required to have a generic expression defined (using Expression.Lambda<..>)?

Thanks.

This is what I was looking to do:

Using this, I was able to build a lambda expression against an object set dynamically. Worked very well.

Check out Dynamic Linq. Basically you can use strings in place of LINQ expressions until you want to use them. Sounds like it might be what you want.
