IQueryable from runtime type with possibility to apply Where and Select

Question

I have to generate IQueryable from runtime type to feed it to a component. This component dynamically loads the data, so IEnumerable is not an option.

Type genericType = typeof(XPQuery<>).MakeGenericType(myRuntimeType);
IQueryable dataSource = (IQueryable)Activator.CreateInstance(genericType, 
                                                    new[] { NewOrmSession() });

This works just fine, but I can not apply nor Where nor Select because it is not using generic.

Any other approach is possible, since I only need to get IQueryable with Where and Select as output from method that accepts runtime type and, in a way, structured where clause.

Answer 1

I have managed with that code that I posted. Just added Dynamic Linq library and got .Where and .Select with string parameter and params object array.
Then I can do something like:
dataSource.Select("new( FirstName as Name, LastName , Salary)");
and also
dataSource.Where("Salary > @0", 1000)

Also OrderBy is working as well.
So it is solved.
