Create Generic Class instance based on Anonymous Type

I have a class ReportingComponent<T>, which has the constructor:

public ReportingComponent(IQueryable<T> query) {}

I have Linq Query against the Northwind Database,

var query = context.Order_Details.Select(a => new 
{ 
    a.OrderID, 
    a.Product.ProductName,
    a.Order.OrderDate
});

Query is of type IQueryable<a'>, where a' is an anonymous type.

I want to pass query to ReportingComponent to create a new instance.

What is the best way to do this?

Kind regards.
