Question

I want to build dynamic linq.

But I want to dynamically set the table (from clause)

Is this possible?

As always, it depends ;-p

If you want to use the LINQ extension methods or query syntax, then no: this is tightly coupled to IQueryable<T>, where T is the source type. Generics might be an option, depending on the scenario:

public IQueryable<T> Get<T>(int id) where T : SomeBaseClass {     return GetData<T>().Where(row=>row.SomeProp == id); } 

The above could be made to work with LINQ-to-SQL, for example, by using GetTable<T>() (and specially hand-crafted data objects). Of course, to get from a string to generics you’d have to use reflection (MakeGenericMethod) – so not trivial!

Can you clarify the exact scenario here?

It sounds like maybe you should just use a regular command here… for example, perhaps with ExecuteQuery, which takes a string command and loads the data into typed objects.
