Better way to create objects from strings

I'm looking for a better way to create objects based off of a value of a string.

Consider the following:

Input file:

//each Vehicle type has a list of different options
//whose length varies, I provided a simple case
van2006dodgegrand caravangreen~
car2010toyotacorollared~
truck2005toyotatundrablack~


Classes:

abstract class Vehicle: IVehicle{
    public int Year;
    public string Make;
    public string Model;

    ...
}

class Van : Vehicle
{
    ...
}

class Car : Vehicle
{
    ...
}

class Truck : Vehicle
{
    ...
}

Program:

static void Main(string[] args)
{
    char delimiter = '*';
    string fileToRead = "inventory.csv";
    string currentLine = string.Empty;
    List inventory = new List();

    //Open file
    using (StreamReader reader = new StreamReader(fileToRead))
    {
        //while you read each line
        while ((currentLine = reader.ReadLine()) != null)
        {
            IVehicle temp;

            //Tokenize the line 
            string[] parts = currentLine.Split(delimiter);

            switch(parts[0])
            {
                case "van":
                    temp = new Van();
                    ...
                break;
                case "car"
                    temp = new Car();
                    ...
                break;
                case "truck"
                    temp = new Truck();
                    ...
                break;
            }

            inventory.add(temp);
        }
    }

    ...
}

My problem with the code is the switch statement. It feels messy and I'm looking for a better way.

In .Net laguages you can easily instatiate any object given only the full name of the class (=namespace+class name).

Here is a runnable example:

using System;
using System.Reflection;

namespace Test
{

    class MsgPrinter
    {
        public MsgPrinter()
        {
            System.Console.WriteLine("Hello!");
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Assembly assembly = Assembly.GetExecutingAssembly();
            MsgPrinter printer = assembly.CreateInstance("Test.MsgPrinter") as MsgPrinter;
            Console.Read();
        }
    }
}

So in your case it would break down to something like (of course, the names in your parameter file would need to exactly match the class names in your application):

...
string[] parts = currentLine.Split(delimiter);
Vehicle vehicle = Assembly.GetExecutingAssembly().CreateInstance(namespace_name+"."+parts[0]) as Vehicle;
...
