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
van*2006*dodge*grand caravan*green~
car*2010*toyota*corolla*red~
truck*2005*toyota*tundra*black~
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<IVehicle> inventory = new List<IVehicle>();
//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.
