Converting 2 argument Lambda expression to 1 argument Lambda expression (specifying one argument)

Question

I have expression

Expression<Func<Car, Driver, bool>> CanBeDrivenBy = 
    (car, driver) => car.Category == 'B' && driver.Age > 18;

and I want to get cars which can be driven by some driver

IQueryable<Cars> cars = ...;
Driver driver = ...;
cars.Where(CanBeDrivenBy);   // Fail, expecting Expression<Func<Car, bool>>

So I need to convert Expression<Func<Car, Driver, bool>> to Expression<Func<Car, bool>> (specify driver)

Yes I can use

cars.Where(c => c.Category == 'B' && driver.Age > 18);

but I need solution with expression which can be changed dynamicly. And I need to pass Expression (using entity framework)

Answer 1

This WORKS

I wrote this function to reduce number of arguments from 2 to 1 by specifying the second argument.

public static Expression<Func<T1, TResult>> Bind2nd<T1, T2, TResult>(Expression<Func<T1, T2, TResult>> source, T2 argument)
{
    Expression arg2 = Expression.Constant(argument, typeof(T2));
    var arg1 = Expression.Parameter(typeof(T1));
    return Expression.Lambda<Func<T1, TResult>>(Expression.Invoke(source, arg1, arg2), arg1);
}

Usage:

IQueryable<Car> cars = ...;
Driver driver = ...;
cars.Where(Bind2nd(CanBeDrivenBy, driver));

arg1 is temporary storage between calls.

Is there any system equivalent function?
